Can anyone tell me what this is?!?!?! Are they some sort of pineapple sponges? Their all over my sump, havent seen them in my main display yet. Should I be worried

Got a question for yall!

Noticed this on my zoas today before doing a water change. Any clue what it is or if I should be worried! Currently only on this colony of zoas

Anemone got stuck in the wave maker... the foot still looks good/ puffed up! What yall recommend i should do? Remove it right away or leave it to see if detachable still?

Got the bacteria bloom taken care of!! 😮‍💨 added a air stone for 2 days and cleared right up! Now just hopping my hammers dont die, everything else's looks good tho!

Someone asked for a video to see the flow for my hammer coral issue. Currently both of them are around 90-130 par

Either i have bad luck with hammer coral or something is wrong with my tank cause I cant keep them from staying closed up. This is my first hammer that has died and the one that is on the rock seems to loose heads. Also would there be a reason for my star polyp to not open?
