Hello ,
I have a 8 month old rsr 250 and currently my tank is consuming 45ml of Bionic 2 part plus im adding baking soda to keep up with the demand It seems like the more I add the more the tank wants . What am I doing wrong ?

I used to dose that much a day to a 29 gallon tank I had,so it does not sound like a lot to me. My tank had SPS, LPS and a very large clam. I think the clam used most of it. It is art relaxant to your corals and other things in your tank.
What size tank do you have?
