Any objections, or better ideas?

Ps thanks to all of you for the info.

even just 2 x 20g water changes in one week will be fine. that ol saying never turns ya wrong. the large water changes of 20g wont hurt its what i do weekly on my 90g with 75g sump so if you do 2 say with a few days apart will be plenty.



to me phosphate is the one thing that i absolutely have to keep in check, i wouldnt dare run a tank without gfo although i have many many times but after doing it on the last few tanks it works and if you start it early it works very well.

still though i dont think high phosphates would melt all your softies in one week...... all of a sudden........ it would take something stronger, maybe from the scrubbing of the algae?? stuff tends to build up in the rocks that can get nasty over time, powerheads miss it and flow cant reach it so untill that day the brush hits it its sitting there rotting and waiting to be disturbed. softies and leathers absorb alot of whats in the water, nitrates they can handle in small amounts but larger amounts and not so much.
