RO/DI

[Pierce09]

Is it necessary to use ro/di water for a Fish only?

 

[Desolas]

No, but I would anyway, or at bare minimum us DI water. Adding more chemicals will remove chlorine from your tap water if it is present, but you still may end up with trace phosphate, nitrate, or silica which will fuel diatom blooms.

I tried FO with local tap water and ended up with alot of nuisance algae problems.

Ditto for same reasons. Healthier for the fish, and less algae problems.

hi.
Let start with just RO, and most of the time, it is sufficient to make everything happen. If it does not do it, it is about the same to get RO/DI in the first place compare to getting RO and DI later.

IMO,,,,RO/DI isent all its cracked up to be but it is a good place to start for your fish only just get a large uv sterilizer and leave it on 24/7,,,,,,,,alot of alage blooms can be due to phosphates introduced wile feeding,,,,or lighting shifts...

If you can do it now you might as well. You will eventually say like everyone else here has said before, that you want to keep corals. For smaller tanks you could probably get away with a tap water purifier but If plan on a lager tank ro/di unit is the way to go. Your fish and eventually your corals will love you for it. Also you will want to kill yourself if all you are dealing with is algae.
