I'm using a Genesis Renew system which is fantastic.I do daily water changes, but I take the easy way out. I have a DOS that sucks out 4 liters and sticks 4 new liters in every day at 1pm. I only make salt water every 10 days.
its possible to make a system with an Apex controller, pumps, float switches and a few water tanks. Or I bought a Renew system from Genesis Reef Systems. It helps that my display tank is on an exterior wall so I could put everything outside and I live in LA so it's always warm.Do you have a thread that details how you do this?
I have it change through my refugium, which empties into my sump. No one has any idea anything happens inside the tank!
The system is a bit pricey for what it is, but all I do now is make 30G in my mixing tank every Sunday afternoon and I don't lift an ounce of water.
