Reefing newb
HI, have a silly question to ask
I have a 260 gallon mixed reef tank. We live in Australia and during the summer months particularly lose a lot of water.
I have a 18 gallon ATO container that gets used over a 2-3 day period. I am very aware of the salinity drop with that much RODI water entering the tank over a week. So I alternate the fills on the ATO container between fresh RO and salt mixed water.
If I am using approx 112 gallons of saltwater (roughy) a fortnight and parameters are good do I still have to do the 200 litre water change I normally do every fortnight ?
It seems to me that most of my water is slowly being changed over that fortnight anyway ?
