I really didnt want to like that post but it was thorough so ya know...
Are you still at non detecable N&P levels? Lowering the alk was a good starting point but i gotta believe its the long term zero’s that are killing you....
If you still want to avoid dosing to keep levels up then IMO you gotta try consistent supplemental feedings of some sort. Be it fuel, roids, acropower etc... a couple days a week should suffice.
They gotta have something to eat! Theyll survive a while w/o food but long term is whats starving them out I think.
