How many gallons I have to change for my 125 tank. Please I need ideas!!!

I would recommend 10-20% weekly for a healthy system. Is it a reef or fish only? How much livestock?

Is Reef and i hace 130lbs live rock. Also I have 11 fish and 30 gallons of sump.

Yup then I would do 20% weekly (that's what I do on my 55g) if it was me...

20% or 25 gals.

Every week?

10% is the normally accepted min weekly change. If nitrates climb you might need to do bigger changes.

I'd say every couple of weeks would be fine. It also depends on your bioload, parameters, feeding etc.

May I ask why you have a reef tank with 11 fish (assuming its established) and don't know how much water to change? Did you buy it established or had it a while and just started having problems? Or never change the water before? Just curious!
