is ro/di needed for sharks, specifically coral cats? ive been running a fowlr setup off of tap/well water with no problems, but i have no idea what the tds are.
I would agree in most FOWLR setups as long as you haven't had major algae or nitrate problems, granted those could be from other sources. However, in your case I would definitely get your water tested and pay close attention to the metals within your water. These metals can/will mess with the sharks sensory system and can bother them quite a bit. That would be my main reason for encouraging you to use RODI water.FLESHY;4738266; said:I would say the opposite of the above.
If you can get away without RO/DI, the better.
The fact of the matter is that we can never make water with better buffering or more complete than what it naturally is.
The less you take out of your h2o, the less you have to put back in.
You also wont have to spend the time or money on RO/DI.
If you dont have to, dont. But I recommend getting your h2o professionally tested first.
I agree with Zoodiver. If your city water is chemical, metal free, then use it. The main use of RO/DI is for the benefit of Corals which are far less tolerant to phosphates, nitrates, chemicals, and metals.Zoodiver;4738841; said:If you use city water, just watch the copper levels in it.
