Time for an update. The tanks are doing well. The anemones are getting very large and space is running out. It's a good thing that BTA are compatible with other types of anemones.
I added the Coralife marine hang on filter/protein skimmer which is loaded with carbon and filter floss. It is rated for up to 30 gallons which doesn't do much on my tanks. But it's a better way to house my carbon (using the ones from RO canisters even though i'm still on tap water). I also upgraded my powerheads to 6 Tunze turbelle 6055 on a wave controller. Just on short pulse mode from A to B.
Water changes are now up to once a week of 4 gallons. I can't keep up with the algae. I have never tested PO4 before, but nitrates always test at 0. Once a week I have to pull it off the egg crate (causing flow issues), and macro grows crazy on the rocks. I can't stick my hand in without gloves on as the anemone stings hurt too much.
I'm debating on upgrading to larger tanks, or just keep them as is. Larger tanks will give the fish more room but they also just stay in their anemones all the time. Also considering moving two pairs out into other systems, but don't really want anemones in the other systems.
Also considered adding some other type of fish to eat algae, but I think that's a death sentence with all the anemones.
