Tank maintenance? What is that? LOL....
I actually like doing tank maintenance. I can almost hear the corals and fish saying "thank you"
I like to keep a clean tank..or as clean as possible given that I feed my fish several times per day and also spot feed all LPS and anemones on a regular basis.
Here is my routine for my 90 gal and 30 gal:
Daily:
Check temp & PH monitors
Check sump's water level
Check auto top off reservoir
Twice weekly:
Clean skimmer riser tube and collection cup
Clean overflow's prefilter sponge
Clean front glass IF necessary with magfloat
Weekly:
Replace carbon IF in use
Blow off rocks in 90 gal
30% water change on my 30 gal cube, blow off rocks, scrape coralline algae from all sides
Test both tanks for alk, ca, mg, and nitrAtes (more often if needed)
Biweekly:
20% water change on my 90 gal Reef, blow off rocks, scrape coralline algae from all sides
Monthly:
Nothing
Every three months:
Change phosban media
Clean out sump & overflow during water change
Every 8 months:
Replace all PC bulbs
Every year:
Replace all MH bulbs
To clean out the overflow and sump area, every 3 months or so, I siphon out all the detritus during a water change.
