Hey guys, so I have a 75 gallon tank, fairly new setup, about 3 months, almost 1 month since cycle has finished, so far, all I have in the tank is one juvenile Yellow tang and one Gsp coral frag. But lately I've been having some green film Algae issues all over my rock, it's not hair algae, it's similar to coralline in the sense that it's just basically a coating or film I guess on the rock, my ph is 8.2, ammonia 0, nitrites 0, nitrates 5. Also I have 4 54w t5 bulbs, 3 ati blue plus, and one coral plus bulb which are only on from 10am to 2pm. My rodi water comes out at 0tds (tested with an in line tds meter). The only thing I can think of is my ATO reservoir (food grade 5 gal bucket) is the cause of the algae. I don't believe I can test for tds in my ATO reservoir because I add a few drops of Seachem Prime to ensure the water is completely dechlorinated if any chlorine got past my rodi system. Any insight would be great! Also the tank is barebottom with about 100lbs of dry rock that used to be in my old saltwatertank but I let it sit outside for a few months and then just reused it. Thanks in advance.
*Also tang police, the juvenile Yellow tang will be the only fish in my tank for the rest of its life in there, no other fish will be added so that way he can always be stress free and have plenty of space to swim
