If you've followed the group for any length of time, TomBarr has mentioned
several times that phospate is one element that is usually linked to algae
problems... it was in mine....


Yes, phosphate is associated with algae problems, but I think what Tom Barr
emphasizes is that it's the *lack* of phosphate that's linked to algae
problems. Filtering out the PO4 will most likely not fix the algae problems.
What will do it is adding back all the deficient nutrients other than
phosphate.

Thanks Alex.
Two things: tap water source and very bad test kit.
Other thing: do you add any so called buffers to lower pH?
If so, stop right now.

It's extremely unlikely your tap water has 4ppm. Call and ask for that
matter.
Large 50% water changes should reduce the level down by 50% to
whatever the tap is. If not, the test kit is junk.

If you use CO2, CO2 and NO3 are about 90-95% of the issue.
Work on those.
