Daily = feeding and dosing some supplements, maybe 5 min?
Weekly = 10% WC, clean the glass, clean out skimmer cup and skimmer, replace filter floss, refill ATO container, testing a bunch of parameters. Breaks down to about 20 min for the water change, 10 min to clean the glass depending on if I do the back wall, 45 min for testing (if I just test the basics, then 20 min) and maybe 20 min for skimmer, floss, and refill of ATO container so call it 1.5 hours tops.
Bi-monthly = 15 min to replace carbon and clean out carbon reactor.
Monthly = 15 min to replace GFO and cleanout GFO reactor.
Quarterly = Vinegar soak and clean MP40 wetsides, make more 2-part and refill dosing containers. Guessing about an hour.
Plus whatever time I need to turn on/off RO/DI, replace RO/DI filters.
Time researching stuff = 15 hours or more a week
Time on the forums here and elsewhere = about 20 hours a week [smilie=lol.gif]
The thing is, there is ALWAYS another project or upgrade I want to do that takes more time . . . but that's the fun of it all.
