Yes. But everything alive must be thoroughly dead and washed off/out. And keep in mind the rock is rough and cichlids dart about and accidentally bash into the rocks. So you may have more scrapes and eye-gouges with live rock than you would with river rock.
Yes, KH out of the tap is 2.9-3.2. I was trying to help it a little. I am planning on using my existing sump and not a filter. Do you think I should use a filter?
Thanks, sounds like a good plan for the substrate.
I plan on using my existing 75 gal sump changed into a wet/dry with bioballs in the first section. Would it be a good idea to add some of the existing live rock in the second section to help buffer the water?
Sorry for all the questions but I am trying to use as much as I have for this setup. As long as it's the best way to go.
Unless the live rock is crushed, it won't help much.
