My crazy Cleaner Shrimp is hosting in my Rose BTA now. Literally, it stands in the anemone and just hangs out. Amazing.
One of the benefits of selling RO/DI units, I have plenty of filters on hand at any time. So I swapped out the sediment and carbon block prefilters this week, since it is June. I'll change them again in December, as this seems like an easy way to remember.
