I just added phos-zorb to remove the phosphate if there is any.
I should not trust my test kit.
I do have a bit of algae so from what I can tell I must
have a bit of phosphate. Is that the only thing that
algae need to grow?

Well, algae will use the nitrates too. But not all are measureable, dissolved organics may be breaking down at the same rate as the nutrients are getting used, so even though you measure no NO3 or PO4, doesn't mean it isn't there.

You have a very good point thx

Can anyone suggest a good phosphate removers and where is a good place
to buy it at a reasonable price you should pm me your suggestions.

Thx

The Two Little Fishies reactor and media is a good system, can be found at most shops for a decent price. I don't think there is a big price difference among stores, so it's probably best to support your local shop!

I don't mean to hijack this thread, but I have a quick question... do you think it is a good idea to run a phosphate absorber when starting a new tank so it's phosphate free from the beginning?
