To use RODI or tap?

[speedjester]

I’m starting a 300gallon (stock tank )pond build for my sharks. Im wondering if I can get away with just tap water. It would be treated with prime and the tank will seeded and cycled. For a few weeks while I get everything setup. ( temp and filtration) as it will be located outside.

Thoughts?

What about combining RODI + RODI waste water? You could run some cuprisorb and gfo in the tank after to take care of metals and phosphate.

Yeah, don’t use tap . I used straight conditioned tap. The TDS crazy high and my tank became green and fuzzy. Got a RODI from a friend and use distilled for top offs when I don’t have RODI water ready. Vast improvement.

i would ask Jay Hemdal

he's a staffer that has shark experience. not sure what kind of sharks you plan to keep but 300 gl is pretty small.

He said the tank will be outside. Don't think he is worried about algae.

If I were you I would sure try to use RODI water, many years ago I can remember using tap water though. I would do your best to stay away from Prime.

I have two bamboos and Coral Cat. Foot print is pretty good. 6ft round it’s actually I believe 365gallons. But I’m keeping it down 3-4” so estimating. When and if the bamboos outgrow it I’ll go for something bigger. Right now there in my reef DT with all the rock work I’m sure there cramped. Should I say the coral cat is cramped. The bamboos hardly move. Lol

It’s in my screened and covered lanai. I kept a 180 out there for 3 yrs. Absolutely no issues. No water changes for the last yr and a half before I took it down

The only good thing on Tap for Marine Aquarist is good Lager.

If you put the waste and rodi water back together isn’t it the same as using tap water that was run through a sediment and carbon filter? Or is there some reasoning that I’m missing?

 

[AydenLincoln]

Can you? Yes! Should you? No! For multiple reasons including various containments/additives in the water that can’t be filtered and the possibility of bad algae issues that a poor water source doesn’t help with.

I kept a fowlr for over a year with tap until i had to break it down. Honestly just depends where in the country you live and how the water is. That said i dont know anything about sharks and how sensitive they are

Yes but 1/3 of the water is RODI, and 2/3 is sediment+carbon water so that if there is something in the water, such as phosphates, it would be a third lower in the filled tank than just using the waste water. Its just an alternative to using 100% tap or 100% RODI, if the OP wants something in-between.

Do you have a link to your city's water report?

Depends on where you live, I usually say get a RODI just to be on the safe side though

I have a Rodi system. It will take me about two days to fill it. Just didn’t want to waste time and RODI if it wasn’t necessary for Fowler tank. I thought I read somewhere that most public aquariums use straight city water and treat to remove chlorine and Chloramines. On the non reef exhibits. Just can’t find it now.
