procyg Posted January 24, 2022 Share Posted January 24, 2022 My 75 gallon is losing the battle against BBA. I have a low-tech tank with 1 48" finnex 24/7 hcl light that is only on from 3 pm - 9pm on the max setting. I have another 6000k LED that i turn on for 1 hour in the morning to feed the tank. My tank is becoming overrun with BBA and its driving me crazy. My well water contains ~10 PPM of nitrates so i am always chasing that dragon with water changes and tried adding lots of fast-growing plants to no avail. I know that adding CO2 would be the #1 option, but my KH is virtually nonexistent and i am terrified that i will crash my tank if i add it. My KH test turns after just 2 drops (the initial drop then immediately changes color after the second drop on the api test kit). I do have some crushed coral in my fluval 407 and some brightwell Nitrat-R resin in my seachem tidal 110. I have started dosing daily Easy Carbon in the hope that it will curb its development, but I am curious what the hive mind thinks about what i can do. Current stocking is 10 Serpae Tetras, 7 Cardinal Tetras, 2 female guppies, 5 black neon tetras, 3 nerite snails, 1 bolivan ram and 1 electric blue acarra. I plan on adding 2 or 3 SAE and 1 bristle nose pleco PH 6.8-7 GH 8 degrees Thanks all Link to comment Share on other sites More sharing options...
