Will's algae issue:

Try 12 inches/10 hrs.

Too much lighting. Reduce the input of MH.

Did it occur to you that not using the amquel caused the GW(The Cl- killed
or hindered the bacteria that helps control NH4 enough to let it creep in)?
You ran a normal and very predictable sequence of events and attempts.

Filtration(Micron/diatom) or UV. It will work and is very predictable:). I
wish I could offer better advice but at this point. The haze can hang out
for a long time and GW can reappear again. Starvation will not beat this
