My tank is about 2yrs old and I start to get this diatom problem back.
I think i was quite stupid to clean up my DSB
and break down my DSB
system after that.because I got cloudy tank for 2 days. I did that cuz i was removing all fish for ich treatment and try to improve my water flow by adding some pvc
with drilled holes under my LR
I put some active carbon in the tank for 2 hrs and my phosphate jumped from 0 to 3(so much of a promise for phosphate free, PS:blak diamon is the brand name). And I start to get this diatom problem going. I try to clean my glass and do water change right after but they come back and cover my glass after 3 days. I baught a phosphate reactor and drop my phosphate back to 0.2 and same thing came back after 3 days. I try to limit my lights down to 6-7 hrs and no help at all. My nitrate is around 5 and I only feed my fish about once every 3 days.
Now, I really need some solutions. Anyone had any exp wioth this? cuz from wat i know diatom should just burn out on themself but those i got just won't go away. I tried to get rid of them for 2 months now. But things just don't change much doesn't matter wat i do.
PS: I even drip Kalk
my water is about the following
silicate i didn't check but the phosban reactor should take care of it with the media removing both phosphate and silicate
