Tipping point

[ScubaSteve]

I know this might be redundant saying this but make sure you prune the HA outside of the tank. When you cut it in your tank it will just spread and get worse. I had it pretty bad at one point and same deal, nothing would eat it. So I snapped, developed a twitch, pulled the worst rocks out during a water change and scrubbed the sh** out of them with a toothbrush in some of the water I pulled out, then rinsed them with fresh mixed SW and put them back in. The CUC, urchin and top snail took care of the remainder. Been HA free since (except for the nicely groomed little patch that they let grow to snack on... I swear they're farming it).

Sometimes you just gotta show some creatures who's higher in the food chain with a little tough love.
