Water Changes..too much,too little or OK?

[Bertie]

Hi,
I have a planted Rio 180 using pressurised co2 and double dosing a complete Fert and wonder whether my water changes are ok or am I overdoing it or not enough?
At the moment I am doing a 50% change once a week and a 10% - 15% daily water change as well. I want to get it right so is that amount ok?

Yes that is very good although you might want to use dry power mix for your ferts as the ei method is guaranteed to work & much cheaper.

Thanks foxfish...I was thinking about EI when my complete fert runs out....
