Tank Help

LEOreefer · Feb 20, 2020

Hello All,
Ive been having some issues with my tank, through ICP testing and regular testing I ruled out all obvious issues. Literally the only thing I havnt done was change out my RODO filters and membrane. I have a 6 stage RODI filter system 150 GPD from BRS. My TDS meter reads 0 and ill post the ICP test from my RO water below. My question is, is it possible my RODO water is bad even though TDS meter and ICP says its ok? The RO membrane is over 2 years old. Im at a loss as to whats going on with my system.

What's your issue with the tank? Corals not dosing well? If your DTS said 0 then your rodi water is good. It could be nutrients, water parameters, light and flow.

Corals are closed and not healthy. My nutrients are in check and ICP of tank water does not show any real flags. I’ve had many successful tanks in the past so this is new to me. I will be changing out all filters and membranes. That’s why I asked if RODI water can be bad even though it’s reading 0 tds
