I think it depends on your local water. If you have high TDS water, they will run out a bit quicker. I think it also depends on the efficiency you want.

I have had mine about 3-4 years off of city water that comes in about 70 TDS (3-stage). My efficiency from the input/output has gone down over time, but it hasn't reached the 90% advised to exchange them. I think they do 92%.

Which one you looking at?

I call Caesar Salad.

Paid. Sorry about the wait.

Whoo!!! Spectra, you lucky dog.

Kim...Holly...gotta tone it down. This isn't the place for having fun.

Most glass shops. They also sell some pretty decent ones on Amazon.

I know costs add up, but DI is arguably pretty important.   There are ways to save money in the hobby but many would say 'don't skimp on DI'.

 

The chlorine / chloramines need special attention too.  Bulk reef supply sells blocks that help with that.

 

Also noteworthy, there are some cautions about drinking water out of an RODI system, it is worth researching that also.

 

I don't know all the answers but wanted to at least throw some thoughts your way.

 

Good luck!

 

He's right. Deionized water makes the water pH = 7. Reverse Osmosis removes any dissolved solids from the water. In many cities, the TDS runs pretty low and you could probably just get away with just using DI water. I think the DI water in our lab runs at 30 ppm, which really isn't too bad. No RO.

Some cities have extreme copper problems or are using well water and RO might be more important, but I think in most big cities it probably isn't too much of a problem to just run DI.

RODI water is actually bad to drink. Since there are no salts in the water, any salt in your body will try to fill the "space" left from the RODI water, ultimately depleting any salts in you body. That's why most water bottles have Calcium Chloride orPotassiumn Chloride added to them to compensate for this problem.

Save the money and wait to get a full RODI system. You won't regret it. Air, Water and Ice has a lifetime warranty.

Maybe use local fish store water or go and buy a large DI container from the grocery store. Most have very, very low TDS, even though they are not RODI.

Also, the Tanks for Teachers tank was "da bomb." There was a lot of hard work put into that tank and I want to thank everyone that put it together.

Whoo! Glad to hear that the ORE got you on the forum. There is a lot that this club has to offer and I hope to continue seeing you around.

Located in Corvallis.

This was a killer event. Thank you Rudy, and thank you everyone for making this happen.

Now let's see some corals.

Pics?

Closing thread tonight.

I really appreciate the closing thread notice. Thank you for everything you do for the forum and club.

Looking good!

Perfect timing for Finding Dory.

That's pretty cool. I definitely see 3D-printers changing the way we do reefing. I was looking on thingiverse.com the other day and saw that they had a protein skimmer.

You just need to buy the cast acrylic and pump. It would be great for a pico skimmer because it can be scaled to size and an airstone could be used as an alternative to the pump.

Good job on the build. Keep them coming.

I am gladly willing to jump on this. Please put me down for one with the cell phone attachment.

He said it was in the garage with quite a bit of temperature fluxes and I believe the lights overhead were never turned off. I also keep mine outside but not in full sun just morning sun to prevent overheating...Don't forget to top off.

Right now I have mine under a trio of LED spot lights that normally run a 12 hour light period, but I turned them on from the reef keeper about a month ago and and just left them on.

 

Temp swings from low 50's to high 80's in the garage. They will 100% live outside though, just make sure they don't get cooked in direct light or water logged with rain. I'd guess a window or back porch on the south facing side of the house would give the best lighting and coverage from rain. Evap is a PITA, which is why I went with the 2liter bottles for the main grow outs. The tapered neck prevents a lot of the normal condensation.

Okie doke. Right now it is just sitting outside, but it does get direct sunlight for about 4 hours a day. Might be too much for them. Thanks for the help guys.

Anyone looking for tigriopus cultures should most definitely talk to the AquaticEngineer.

I got a couple reasonable frags for donation. Count me in!

I'll bring them the morning of.

Nice pictures!

At the moment, mine seem to love being outside.

What's the light period and temperature you use? I am a little unsure.

Welcome. Share the seahorse love.

Some future marine biologists right there.

Good Job!

The tigers look good. Thanks again.
