phosphates

[jhp]

Hi all

I'm currently having a problem with phosphates, they read at 2.0 mg/l
using a sera PO4 test kit.

I'm am trying find out more about phoshates where do they come from
eg. tap water, food, drift wood ?? etc and how
to effectively lower the phosphate levels.

I have discovered that our tap water contains small amouts.
Any comments on pre-filtering ?

thanks
James

Hi James,

My latest test was also 2.0 and my tap water registered .5
I normally wouldn't worry about this since I do 25% water changes each
week along with vacuuming the gravel but with lots of plants I do
worry about algae growing all over them.

This site seems to answer lots of questions.
