So the test kit arrived this morning, and it would appear my phos is quite high, reading 5mg/l, the next and final reading on the kit is 10 so I reckon I need to take action soon.
I firstly measured the aquarium water, then straight from the tap, both gave the same reading of 5, which is something I suppose, just means its nothing i'm doing wrong as such.
Anyway what do people recommend I add to the aquarium to remove the phos?
