A quick update. I have tested the RO water that I use and it tests between 2 and 3 which I think should be acceptable. I have since changed my salt to Aquavitro Salinity and stopped dosing Fusion 1+2 and have noticed the algae starting to die back. I will let it stabilize and then try the dosing of Fusion 1+2 again. For now I think the kalkwasser in topup water should keep my alk and cal up and water changes replenish the rest. I have also changed my light unit since I think my old one was too strong for my size tank. The new LEDs are total 60w.
