Hi, i have 3 saltwater thanks in the past. Due to space issue i had to put my hobby on pause. Recebtly i saw at a local fish store the fluval evo 13.5 and ecided that it was small enough for me to be able to fit at my apartment.

the tank has being up and running for about 3 months now and even though water parameters are good, i cant get ris of the brownish algea that has taken over the tank. This is a very simple setup and i only have to dansels on my tank. Any idea what to do here? As i always do, i do not use tap water. I always use spring water to do my water changes.

Normal in a new tank.
Don’t use spring water you want to use reverse osmosis deionized water or distilled water.
