    Not a problem. Will come out of the rocks. Phosphate flow out of rocks Many people, when they get their nutrient exports going strong for the first time, get worried when more (not less) algae starts to grow on their rocks. It seems really strange, especially when nitrate and phosphate tests have been lower than before. What is happening is that phosphate is coming out of the rocks. Remember, phosphate is invisible, so you can only see the effects of it, and it always "flows" from higher concentrations to lower concentrations (just like heat does). Example: If your room is warm, and you put a cold object on the floor, heat from the air in the room will "flow" into the object until the object and the air are the same temperature. Example 2: If you put a hot object on the floor, heat will "flow" out of the object and go into the air in the room, again, until the air and the object are the same temperature. Now suppose you open your windows (in the winter). The warm air in your room will go out the windows, and it will get colder in the room. The object on the floor is now warmer than the air, so heat will flow out of the object and into the air, and then out the window. Think of phosphate as the heat, and your rocks as the object, and your windows as your export. As phosphate is exported out of the water, the phosphate level in the water drops. Now, since the phosphate level in the water is lower than the phosphate level in the rocks, phosphate flows from the rocks into the water, and then from the water to the export. This continues until the phosphate levels in the rocks and water are level again. And remember, you can't see this invisible flow. It's like a fast flowing, but shallow, river. And it can be much more phosphate than how much you are feeding each day. This flow causes an interesting thing to happen. As the phosphate comes out of the rocks, it then becomes available to feed algae as soon as the phosphate reaches the surface of the rocks where there is light. So, since the surface of the rocks is rough and has light, it starts growing MORE algae there (not less) as the phosphate comes out of the rocks. This is a pretty amazing thing to see for the first time, because if you did not know what was happening you would probably think that the algae in the scrubber was leaking out and attaching to your rocks. Here are the signs of phosphate coming out of the rocks: 1. The rocks are older, and have slowly developed algae problems in the past year. 2. Your phosphate export is new and strong, maybe only a few months old. 3. Nitrate and phosphate measurements in the water are low, usually the lowest they have been in a long time. 4. Green hair algae (not brown) on the rocks has increased in certain spots, usually on corners and protrusions at the top. 5. The glass has not needed cleaning as much. Most people have never seen the effects of large amounts of phosphate coming out of the rocks quickly. But sure enough, it can. How long does it continue? For 2 months to 6 months, depending on how much phosphate is in the rocks, how strong your export is, and how many other phosphate-removing filters you have (macros, GFO, carbon dosing, etc). But one day you will see patches of white rock that were covered in green hair the day before; this is a sure sign that the algae are losing their phosphate supply from the rocks and can no longer hold on. Now it's just a matter of days before the rocks are clear.

  18. With more people wanting to use natural filtration for their tanks, we are going to look at the two main types of units that you can put on your system: Chaeto reactors (or "algae reactors") and algae turf scrubbers (ATS). We won’t be looking at refugiums however, since those have mostly a different purpose. This will be a multi-part post; the next post will start with the basics, so if you’d like anything in particular to be covered, let us know.

    Chaeto Reactors compared to Algae Scrubbers

    Yes if you compare strands of both with light behind them, you will see. And by "dense" it's meant the density of an individual strand; not a bunch of it. I had said before that this is based on observation of several thousand scrubbers. If someone would like to donate warehouse space in W. Los Angeles, I'll set up the tests to get data. Not thin mats, like scrubbers are designed to be. That's why they are designed to be thin. No, because only one side (and only part of that side) is perpendicular to the light at any given time. The rest of the time the chaeto surfaces are less-than-bright, or dim, or dark. Good to hear; they are fun to watch. Yes this slime and hair is killing and pulling nutrients out of the chaeto. A scrubber is simply designed to have just the slime and hair.

    Chaeto Reactors compared to Algae Scrubbers

    Glad you like it. No you should not really be wondering; algae grows based on conditions, so you can't really tell it what type to grow. But you can look at the growth, and figure out what you can alter in your setup.

    Chaeto Reactors compared to Algae Scrubbers

    Chaeto Reactors compared to Algae Scrubbers, part 3 By Santa Monica Filtration Now for nutrients. Nutrients are defined as inorganics, not organics. The word "nutrient" is sometimes confused with "nutrition", and maybe in restaurants the words might mean the same thing, but for aquarists they are totally different. Nutrition food particles are mostly visible, but nutrients are invisible, and for aquariums the nutrients are: Ammonia/ammonium Urea (pee) Nitrite Nitrate Phosphate Iron CO2 Organics: These are food particles, and most of them big enough to see. They can be apples, pellets, nori, baby brine shrimp, flakes, peanut butter, poop, mucus, leaves, twigs, fish eggs, and other types of detritus, all of which are eaten/consumed by some type of organism. Organics are usually very visible when concentrated, and only after the organics get digested by a long chain of animals and bacteria do organics become invisible inorganics (this is called “remineralisation”, because they are now basic minerals once again). Organic food particles (which include waste) can be large, small, or dissolved, and if dissolved in water then the water may be cloudy or clear. For example, if you take mucus and blend it in water, the resulting dissolved organics would be invisible. Natural reefs are very highly loaded with organics, especially at night (sometimes a night diver cannot see his own hand because of the camera light reflecting off of the mass of particles). Lakes even more so, so much that sometimes you cannot see more than a meter underwater in full daylight. Aquarium keepers however tend to want ultra “clear” water, where all the natural food particles are removed from the water. Algal Structure: The structure of algal cells make the algae thick or thin; solid or soft. The thinner the algae is, the more surface area it has, just like small particles of sand have more surface area than larger pebbles do. This increased surface area has more contact with water around it and thus can pull in nutrients faster. And the softer the algae is, the less structural cellulose-like material (like celery) it has. Hard structural cells, like celery, are great for holding a shape but bad for photosynthesis because there are less photosynthetic cells like there are in a leaf; so harder/stiffer algae absorb nutrients slower. Therefore for faster nutrient absorption, you want thin and soft algae. Chaeto: Has a firm structure that holds it's shape, and is about 1 mm in thickness. Nutrient absorption is slow. Green Hair: Has a soft structure that does not hold its shape, and is about 0.1 mm in thickness. Nutrient absorption is fast. Slime: A different category altogether. Light: Photosynthesis does all the nutrient filtering, and it requires light; if the light is reduced, then filtering is reduced. Two facets of algal cells can alter the light: Translucency and self-shading. Translucency is the ability of light to go through a strand of algae; if light can do this, the light can reach cells further inside or on the other side of the strand and do more filtering there. Self-shading is when one strand of algae shades another strand; when this happen to a large degree, the growth of inner portions of a clump of algae slows down or dies, as outer growth is added over it. Thus the clump may appear to be increasing is size but the inner portions will actually be dying and putting nutrients back into the water, sometimes faster than the newer outer layers are taking the nutrients out of the water. And the larger the clump is, the more the inside starts dying. Only the outside portion grows. Chaeto: Non-translucent (opaque), with high shading of other strands. Green Hair: Medium to high translucency, with medium shading. Slime: Low translucency when thick, and high shading. The graphs of the following study show the light-blocking characteristics of chaeto: "Production within dense mats of the filamentous macroalga Chaetomorpha linum in relation to light and nutrient availability" http://www.int-res.com/articles/meps/134/m134p207.pdf Fig 5B shows how, under bright light, chaeto productivity (filtering) drops 72 percent with just 2 cm of chaeto thickness. And this does not take into account any dying chaeto underneath. With green hair algae however, the green hair filaments are very thin, and translucent, so light and water flow spread throughout the algae, thus maximizing filtering. No part of the algae is "on the dark side of the growth" like it is on almost all parts of chaeto.

    Hello from Hillsboro

    Sleek black, looks better than the mfg pics.

    can i use some 9m old unused sand?

    Should still be ok, if you let is aerate and settle.
  24. Using Seaweed to get rid of nuisance algae in your aquarium or pond, part 3 Thinking back now to the oven, and to the heat concentrated inside it, it becomes clear that if that same heat were let out of the oven, your house temperature would get hot, but not near as hot as the oven was. Why? Because the oven concentrated the heat into a small area. And, if you let that same heat outside your house, it would not warm up the outside air at all, for the same reason. If someone did open up all the windows and doors and let the heat out, you would need to stand right next to the oven to get any heat at all. So even though the same process and amount of heat exists, the area that you concentrate it in makes the difference. So going back to photosynthesis, which is the filter we want to use, the amount of filtering it does is based on the concentration of certain things: The first is chlorophyll. This is the filtering engine that pulls the nutrients out of the water, and the more of it there is (higher concentration of algae), the more nutrient can be pulled out per hour. The second thing needed in concentration (and to keep the chlorophyll alive) is: Light. Any part of the algae that has reduced light cannot pull nutrients out as fast. This is only up to a point however: If the light gets too strong, then the photosynthesis completely stops and the algae die. So the trick is to keep a strong, even, constant level of light concentrated on all the algae at all times, with the exception of the "off" time for the algae to rest. And let's not forget about the concentration of what we want to filter: Nutrients. This is like the heat in the house. If you keep the windows and doors shut, you will feel more heat. But if they are open, especially if cold wind is blowing through the house, you will need to be right on top of the oven to warm up. Algae, too, need to "feel" and be near the nutrients, which are stronger near air/water interfaces that supply more CO2. Once you are warmed up by the oven, it's time to let the next person stand next to it. Then the next, etc. You can even go into high rotation of letting many new "cold" people stand by the oven for a brief instant, while the others move through the room waiting for their turn. This is how nutrients are supplied in high amounts to the algae; a new group of air/water interfaces is brought in every second, so that the algae see and feel a high concentration of nutrients right next to them, even though a few millimeters away the nutrients are low. So let's see how we can build such a filter that let's us concentrate these things.
  25. Part 1 One of the neat things about nature is that it's had a long time to figure things out. Especially under water. Here, nature has figured out how to reduce all the "nutrients" to very low values, and also how to feed every aquatic animal (as well as consume half the world's CO2, and produce half the world's oxygen), by just using sunlight. Not bad. Maybe this concept can be used to help your water pets. Well of course it can. And it is already doing so, sort of. It's just not being used enough, or even on purpose. It's sort of the difference between a bicycle and a motorcycle, or a snack and a big dinner. Or even knowing you have a dinner in the first place. It's called photosynthesis. You have all heard about photosynthesis; it reminds you of trees and science experiments. But how can it help? Well the basics are this: Photosynthesis takes carbon out of carbon dioxide, and uses it to build living things, and it releases oxygen in the process. You've probably also heard that all living things contain carbon; well, that's where the carbon comes from, and photosynthesis is how it got there. The living things that photosynthesis builds generally are plants (on land) and algae (seaweed and phytoplankton) in the water. Then, anything (like you) that eats these plants or seaweeds will get the carbon you need to grow. Oops, there is one more neat thing that photosynthesis does when building these living things: It uses Ammonia, Nitrite, Nitrate, Phosphate, and many metals like Copper and Iron too. Sounds like an ideal filter, right? Removes Ammonia, Nitrite, Nitrate, Phosphate, CO2 and metals, and put oxygen into the water. Also sounds like an ecosystem, like the ocean, or lakes, or rivers. Because it is! That's how the oceans, lakes and rivers are naturally filtered! So we will be showing you how to build your own DIY versions of these neat filters (for fresh or salt) in the coming posts.
