Just saw both of my snails alive :) So I am guessing its not for any die off

I was wondering.....does melting of corals cause spike?

Just to put an image of my overfeeding in the last few days : Sandbed had chucks of mysis lying around :lol:

Um.. ya, if you've got more food laying around than your clean up crew can clean up then I'd say you have an issue :-) Or rather, had an issue :-)

Melting of coral tissue can cause a spike if there's enough of it. NOrmally if it's just one or two then it's not a huge deal as you'll likely skim it out, but then again it also depends on your total volume and how well it can dilute the effect of coral die off. Coral die off is simply more organic waste decomposing in your tank.

I don't have any official CUC other than the two astreas (they only like algae), cleaner (who doesn't like leftovers, he just loves fresh meals from corals mouth!). The bristles do wonderful job but they just have enough to eat already. All the corals always have their tentacles out during day and night (I spoiled them).

The elegance melted so I am guessing that might have a play in this too. And I don't have any skimmer.

Funny thing is, the brownaporas are not affected yet. I can see the bonsai's polyps. Weird stuffs!

Wow, you've got quite the challenging setup there don't you :-)

Like what? Because of no skimmer? :P

I've run skimmer less before. It's not impossible. I would just consider it more of a challenge. Especially without a clean up crew LOL.

Hihi. Denny told me not to add clean up crews. I had hermits and they did awesome job but was buggy for my zoas.

Thanks for the appreciation btw :D

Ya clean up crews are one of those matters of opinion. Some people don't bother, some people swear by them. I personally love watching hermit crabs scavenge.

I loved them too. They keep every nooks clean; particularly the zebra hermits. They were so cool! But my zoas didn't love them and I loved my zoas more so had to take side with the zoas :P

This hobby is full if no win scenarios :-(
