You dont need to do water changes every week unless your trying to drive something down.
The c remora was good for it's time. If you change from "Not Sure" to I am getting a skimmer then pass on the remora and get the Aquamaxx. You'll never regret it.a local guy is selling an aqua c remora which i'm thinking of getting. Not sure yet.
Or trying to keep your parameters in check. With no dosing and more corals introduced in the tank alk, calc, and mag will require some form of replenishment.
You could dump the Chemipure and Poly and buy the Purigem 100ml. The 100ml is already in a bag and helps your skimmer with nitrates and polishes water crystal clear.Will I still need to add chemi pure blue and poly filter if I use a skimmer?
