The rock is starting to look cleaner on a plus side. How high are po4 levels

Ya, the rock isn't bad, just not as clean as it could be. PO4, last hanna check was 0.21. Probably a bit lower now, I've been using fozdown. With a Elos test, it's blue :) I can never tell where exactly it sits with those kits.

I used cerith snails for the diatom bloom, they mowed through it pretty fast.
Don't have a hanna checker nut found salifert pretty good. I'm willing to bet buy the end of your 3 months it will look supreme.

I have some conches, and a bunch of large sand burrowing snails, they move stuff around pretty good. It's getting better, so not worried. Just need the rock to build enough internal bacteria to denitrify the NO3. And stop feeding green algae :)

The good - NO3 down to below 1ppm. PO4 down to about 0.1ppm. Algae vanishing. Corals coloring up well, mostly.

The bad - FFS, looking at a frag last night thinking it's looking pretty rough. Almost like the mother colony did when it was infested with AEFW.....well ya, there ya go. Took it out and dipped it, and infested. FRACK!

Oh well, sh1t happens, right?

Plan A. Do nothing. See what happens.
Plan B. Natural control, add a wrasse or 4 and some peppermint shrimp.
Plan C. Create a full SPS system with no acropora. This has potential, and I've never seen it before. Could be cool.

Omg how can that possibly happen? I would get a wrasse yes :sad:

No idea. All frags were bare tissue and well dipped. Nothing wet transferred over except the clam. Maybe that was it. A couple frags from a shop added, but dipped and some FW removed. No other anythings from any tank added. Weird, eh?
Oh well....

Man that sucks. All that work.
I vote for plan B and C

I have four yellow coris if you want to try one :idea:

Japarto has one waiting for me, but thanks.
