When I switched from my 30 gallon to my 125 I stopped doing normal water changes. I actually set up an auto water change system because I didn’t want to deal with the maintenance. After having it run a couple months I shut it off and monitored it. The refugium has been able to keep up with the nutrient export; enough so that I even turned off my skimmer. The chaeto is now my sole means of nutrient export. I do add the Red Sea trace elements but that’s much easier than doing water changes.Sduvall81,
How much water change do you do monthly?
I am in market for a bigger tank but scared if having to do tons of water change.
As long as you are taking care of the fam and not spending money you shouldn't be on it then all good really. Just make it look awesome and you're golden.
