Re: Mega dosing the day before a water change - or - Inviting the beast to dinner

Thomas Barr presented an interesting additional tactic for
keeping algae at bay -- maybe you could call it the

Then, right after the water change, no more KNO3 or KH2PO4
is added, since the levels will be about 10ppm and 1ppm
respectively?  But K2SO4 and traces are added right after
the water change and then a maintenance dose of whatever's
needed during the week, yes?
