So how do we know when to resume water changes? When is the nuisance algae is enough and the dinos in check that its safe to try? I'm dealing with the same as Billybatz it seems. Tons of red/dark growth all over sand. So much I finally sihponed it out last night. And now it seems like getting green hair algae outbreak. Dinos are 99.5% gone, only a few scattered in my overflows and return plumbing.

Is this saying that my nutrients from the dirty method are high enough and dinos no longer able to keep them in check?
