Weve had a biocube 29gal since 2014 or 15. We also within the last year bought a used established tank that was 6 years old. About a month after moving it and setting it back up I believe it either. 1. Stirred up too many toxins, 2. Re-cycled. Anyhow I lost everything but 2 clowns. And I battled nitrates like crazy. Anyhow it also got cyanobacteria (probably had it when we bought it). And I stupidly used the same syphon for both tanks on cleaning day and it went into my biocube. So I treated both tanks and of course nitrates are now crazy high in both tanks. And I've lost all but one clown in the large 90gal tank including snails and crabs. And all but an urchin, pistol shrimp, peppermint shrimp, and a couple snails and a crabs in my biocube. I've neglected the big tank because I just want to take it all down and start over. The biocube I plan to just probably remove half the sand and 75% of water to help with nitrates, add some new sand, and change chemipure more often. Anyhow. My question is more for the big tank. I want to remove all the sand first. Then Can I treat the tank again for cyanobacteria before breaking it all down? I see theres some red growth on the glass below the sand. Once I treat for that and it's gone I plan to completely drain the tank, and completely empty our 2 eheim canister filters and start with all fresh media and filter pads. But what should I do with all the live rock in the tank? Does it need some kind of dipping process, or could it be left in to recycle the tank? Thanks
