When do you do your WC/ maintenance and what's your levels.

Just did one New Years' Eve. Before that, my last one was in the summer. I would do one every month or month and a half if I could find the time/ambition, but it seems like every few months is the best I can manage over the long-run. Luckily I have big sumps (90g wide) with two skimmers (Deltec AP702 and Deltec SC2060 skimmers (rated for 375 gallons), multiple reactors with Hydroton, lots of different macroalgae in the refugium, etc. to help keep up the water quality between water changes. On the 165g, I do massive (if infrequent) water changes of between 80g and 100g. On my RBTA/Dendro/Pulsing Xenia 93g cube, I usually do 40-45g water changes.

I don't necessarily recommend MY water change schedule for others but that's what I have been doing due to my unusual work schedule and the fact I need to place two 55g water barrels in my living room when its time to do a water change.
