Growing your own phytoplankton


Recommended Posts

Has anybody on here ever grown there own phytoplankton before? I just built a phytoplankton growing station and I've got everything all ready except I'm not sure what to use as fertilizer, I keep seeing something named f/2 which is a specific for marine algae fertilizer. I also see people using miracle grow, not something I would do personally as I don't know the exact ingredients, but some reefers on forums say it's bad because of heavy metals, mainly copper. While doing research I found two separate formulas for the f/2 fertilizer that everyone says to use and both contain copper sulfate?!? That to me seems like that last thing I'd want to put in my tank.... with that being said, anyone know of something different to use as the fertilizer? I was almost thinking of trying a mix of potassium nitrate and some other stuff that would be already used to dose tanks with. I'll attach the formula for the fertilizer that everyone seems to be suggesting to use.

I will definitely be selling it for super cheap, I just want to make sure I'm using the right food for the phyto. I ended up just going with the f/2 formula that I was being recommended too use. Still seems weird to me that it contains copper though... I think I'll do some tests and see if there is any copper in the final product before I use it.

Got the phyto fudge light put together. It's just the bare bones at the moment till I can find some sort of case for it. I built it to produce 50w of "full spectrum" light that should get the stuff growing fast.

And for the growing chambers, I'm gunna use 6, depending on how much I end up needing, of these define flip water bottles with rigid air tubing coming off each and will be connected to an air pump to keep oxygen/CO2 gas exchange going + it will keep everything suspended and not settle to the bottom.

      I am planting a new tank for my desk! 1.5 gallons, planted with anubias that has been rooted to a log already. Pearl weed baby tears I believe are planted and wisteria bunched in the background! Still learning and this is my 1st micro tank, so open to suggestions or criticism! I also have a 45 gallon tank meant to be river style tank currently home to tetras and a 5 gallon betta tank supposed to be like a warm creek or pool with light flow. Will post soon!

      Howdy folks,
      In for my first real adventure here, had a false start a couple years ago, but over the last month or two I have gathered gear, some used and some new. I have a 75 Gallon tank used tank (clean) that was already drilled. I have researched for the last month and this is the plumbingI have come up with based on what I have, researched, how it’s already drilled, etc.. Please fact check me and provide any recommendations. Pictures are not for scale, but should give a good idea of fitting type.

      Sump will be a DIY 20 gallon long, or I might splurge and buy a kit.

      2x 1” Drain Lines
      Drain line bulkheads are on the back plate, they are 1” and at the same level as each other Main Drain Line will have a downward facing elbow and a Gate Valve on it Backup Drain Line will have an upward facing elbow and no valve on it 1x ½” Return Line
      Double Pump Setup for redundancy Pump will have a braided vinyl pipe to a barb fitting, from there a check valve to deal with the two-pump system. Will feed into a manifold system, pardon the scale and 3d on drawings. From the Manifold returns to the system with a 90* elbow off the 4-Way straight to the top with loc-line for aiming I put in unions all over the place, I know I’ll have to break down and move this in the next 1-2 years, but did I go overboard? While I want to do it right, I don’t want to waste money either 😃

      Parts List:
      2x 1" 90* Elbow
      3x 1" Unions
      4x 1" 45* Elbow

      2x 1/2" Barb
      2x 1/2" Check Valve
      3x 1/2" 90* Elbow
      3x 1/2" T's
      6x 1/2" Ball Valve's
      11x 1/2" Unions

      I'm not sure if there is already a thread like this but I wanted to put together some builds and repairs I've done using a 3d printer and share the 3d models with others as well as a place for others to share their ideas with one another.

      So the bulb went out on the little cube that I picked up recently, and i'm at a crossroads of where I want to go with this tank lighting wise. I would like to start with high end zoas, and add sps down the line although that's a ways away as the tank was just established, and I'm monitoring fluctuation as I'm going basics with this tank. (carbon, filter floss, water changes) I really like the hood that's on it currently because it reduces evaporation to almost nothing which is a big deal on a 6 gal tank. So if I do switch out the light it would be best case scenario for it to fit in the current enclosure. The new jbj cubes did upgrade the light they came with to an LED but I'm just not convinced that it will put off the par I'm looking for with going through an upgrade. 
      This is the current bulb that is in the tank.
      There are also 2 LED diodes that are blue so its very washed out with whites. 
      If I removed the current lighting components I would be working with a space that is 9.5" wide and 5" tall. The lid has a curve to it so the depth in the middle is 1.75" and tapers down to 1" towards the back of the tank. The tank has a depth of about 11" for the light to penetrate. So I guess what im getting at here is do I replace the current light that I have with a new light? Or do I supplement with more blues, and if this answer whats the best option for that? On of the reasons I am for replacing the light entirely is that I really like the idea of both spectrum being on a controller.   
      Thanks for your input,

      Before I spend a ton on materials for the next build, I want to see if anyone is aware of any large acrylic tanks that are used and/or reasonably priced? Leaks, scratches,  seams, repairs needed etc.. are no problem, my son and I like to restore tanks anyway  
      looking for 8x4 or larger (any size with 48” or more width). No need for a show tank. Cash in hand.
