I hope that I am not intruding on this forum. I have not actually started on my 90 gallon tank but I am on of those people that like to plan everything out a head of time. I am set up my tank as a reef tank so I am looking into everything that I am needing. I would possibly like to dose with limewater (pickling powder) and don't know if I even need one. I also do not want to spend all of the money they want for a reactor. I aslo do not mind using vinegar, instead of CO2. I just don't have the room except under my tank. Anything that can help me I would appreciate it. Thanks.
