None at all
And that tank is amazing I don't want to restart wow
Live rock with coralline is gold
Your bounce, my goodness. I'd backflip into a cold lake for that system.
That pic is strategy gold in my opinion.
You've invested enough in that tank that one last go at uv isn't irresponsible. Amazon allows docked returns of items that don't wow.
Try other easier methods if you like before buying, but uv paired with pre hand cleaning is so powerful for large setups.
Buy oversized. It's not necessarily something you run all the time. It can stay plumbed and off, or in the closet, but assured I've used it tons of times for cures in threads I'd personally not be without one in a large tank in my opinion.
Before part cleaning I think you should try uv. You have a fine balance purple rock setup and though rip cleaning won't hurt it, your overall pic doesn't command it in my opinion if you don't want to rip clean so much work first go.
I was expecting way more coverage that's not bad at all.
Incrementally we should work on the tank ending up with a purchase or a rip clean, you've got a nice setup there no particular rush.
I used uv for years on a 75 gallon, it was a pond sterilizer way oversized and was mounted hidden behind the system. Oversized simply means big as you are willing to oversize. To burn something is the goal
pay to play cheat yep
Any number of cheaper natural approaches can work. Not downing other methods it's just what I'd do post backflip if that was my tank.
