Thanks for the suggestions, Doug, but am not going near anything where I have the possibility of a mini or any other kind of flood
Had that happen a few times at our old house which was okay because the tank we had then was on lino. Now that we're in a second storey condo, a flood is simply not an option.
Only one of three tanks, the 37g, will have sps and lps corals in it. The 67g will house my zoo collection and maybe a few other softies so it will not need a high level of circulation. The 120g will is for my mushrooms and xenia so I can keep a dwarf angel of some type. This tank will also not need high water flow.
Once the tanks are set up, I can adjust water flow on the powerheads as well as adjust the direction of the water flow. As long as I get a low flow spot for the detritus to collect, I can direct my basting toward that spot. I will try out the small powerhead on a stick method (PH set on low flow) for moving detritus from behind and from under the rock.
Geez, I think I'm in for a lot of experimentation over the next while
Will post information on my website once the tanks are up and running and we get a new website host.
