I think it's been just over a month since the end of my "diatom/brown algae "bloom" problem. I still have a bit of diatoms but it's not "blooming". I doing 20%(1gal.) water changes every 3-4 days since then. For the most part the diatom/brown algae seems to be waning a bit, less of it. I think vacuuming the substrate well helped but stirring all that up may have cause bba/bga in which I've rid of so far. I do have a little of green algae, on a couple rocks and glass though.
For my 5gal. tank I've been dosing .5ml Excel daily and dosing at wc's .125ml Thrive/.5ml Jungle StartRight, I've also used Phosguard in which I felt did not help much with the brown algae if at all. I've started to use and dosed twice the past week and a half Seachem Pristine, don't know for sure but it does seem to keep my water cleaner and less brown algae build up on gravel, but idk.
A little history of my diatoms "bloom", light or lack of did not stop it from blooming. As of recently, I've toned down my lighting quite a bit and shortened the hours and directed it to a portion of my substrate. I believe the diatoms grows with light more so than without it. The diatoms/brown algae today grows on my substrate where the light shines the most and not so much where the light is not directed at. oh well.
maybe my prior diligence of cleaning the substrate well getting the majority of the detritus/mulm, now my timely wc's and I believe the start of using Pristine has helped lessen it a bit more.
Maybe Pristine helps some, on the 4th day, the day of a wc the water is clear but the brown algae/diatom is still visible but it's NOT a bloom and just where my lights shines the most.
ammonia/nitrite 0's; Nitrate 10-20ppm; ph 7.8; phosphate ~0-0.5ppm; kh 4 gh 5
Started out, thinking it's a 5gal. tank chore for my grandkid want, now, it's turned into a expensive hobby that I've got only myself to blame fer.
