Having GHA is a natural thing, it’s like Aipatasia eventually it will come in and we just have to deal with it, as long as you keep calm and a good stable value of residual nutrients (no3 and po4) and some natural predators it will go away. Don’t fall in the temptation of stripping your tank of nutrients (no3 and po4) as that will just make things worst.Not sure -- been getting some GHA pockets on my one pile that was started from dry/white rock some months ago (((added during last tank transfer))).
My PetCo live rock (if I can call it that) structure has ZERO GHA pockets,,, go figure.
Mostly I'm just interested in the topic and if I believed there was strong evidence for reasonable benefits (from adding different bacterial strains), I'd probably just do it, even if not trying to remedy any issues.
