so here's what i reckon. instead of adding an enzyme product, e.g. hygrozyme - add a BB product, e.g. vitalink's bioplus. Avoid the gloopy brown stuff intended for soils. They probably have too much food that a hydro colony cannot metabolise and the slime fuckers will accept your invitation of free food.
In your res, and basically wherever you can, add fibrous matt. I used japanese koi filter matting. The principle is simple, you want something water can flow through and a large surface area so the BB can stick on it. They dont float around in the water, they grow anchored on things. We want them to anchor to the roots, so make sure they start by being anchored to some matting.
You can replace ALL your nutrient mix during changes, since they are anchored to your filter and your roots.
If you look back over my recent posts (excluding the deleted ones where i behaved like a DICK) you can see in more detail. Once you've followed these steps and keep ur water aerated so they dont die, you will never see the slime again or pithium. Put in a heater if your water temps are below 25C and see how much your roots love it. Brave words i hear you say?
