I'm afraid I don't live out on the hairy edge like a lot of people with my tanks lol
-50% weekly water changes on all tanks whether they need it or not (more on fry/growout tanks)
-strict 4 week minimum quarantine on any and all new fish
-all filters contain lava rock for biomedia and polyfill for mech media which gets changed weekly
-I use a garden hose to empty and drain tanks. I've never owned a python.
-canister filters get cleaned maybe 4 times a year.
-i've used RFUG, canisters, HOB, wet/dry, and sponge/bubble-up box filters...I've found they all have an appropriate use
-I don't use RO water for my reef (although I'm planning on starting as soon as I install a system)
-most of my tanks do not have heaters - heated by ambient room heat (small enclosed space)
-i try to understock my tanks, and usually end up giving minimum tank sizes way larger than most people would
