That doesn't make sense to me - if the phosphate was being used up, it wouldn't be testing high.
I think chasing phosphate to deal with algae is tilting at windmills.
Both that and your salinity could be causing what you are seeing in your mushrooms. Why are you running your salinity that low?
it is too low for corals
Does anyone have or know anyone who sells live rotifers in the East Bay? I have some on the way, but they may not get here till Monday so I’m looking for something to tie me over.
Thanks so much!
