I am having some problems with my corals, they stopped opening and I am trying to figure out what is going on. All water parameters look good. I noticed this on the live rock. It is at the bottom. I am having a sponge explosion. I am starting to find sponges everywhere. What is this on the rock? Is it a start of a sponge?
What is this cobweb looking stuff on my LR

looks like some sort of sponge

on the bottom glass? Looks to be snail eggs.
Just to make sure, the circled area is what I am wondering about.
OK, I just stared at it a bit longer. I can barely see some other structure that looks like the vent or whatever the tubular opening is called.
Anothe question. Would any sponges be hazardous to leather corals? My finger leather appears to be coming apart. My clove polyps are not opening. I new leather was introduced. It did shed and appears to be shedding a bit more. Would that affect my other leathers? Pictures attached.

Could be. My snails have been busy. I guess I am doing something good. I have a huge number of small sponges popping up on my live rock. A bunch look like fuzzy light green balls. I can see the vent structure. (correct my terminology). I have a nice white one that popped up. Can't get a good angle to take a picture. There are a few purple ones too. also can't get a good angle.

Can't tell too well with the picture. If it has individual threads then it's a tube worm. Kinda like a feather duster. But instead of having feather-like arms, it uses web-like arms to collect food. It's arms can retract into it's mouth to eat detritus and plankton and other small organisms.
But my first guess is that it may just be a sponge. If you feed your corals and inverts with some type of phytoplankton, these will consume them too. But they are not without benefits. They help filter and clean your tank and offer habitat for your micorscopic organsims.
As for your corals, it is probably unrelated. Unless they have been growing on or very near to your corals. If you have a problem with your corals and you just recently got a bloom in sponges, if you feed your corals phytoplankton or anything else, you are over feeding and your water quality may be down. Check you water, and ask questions.

I checked my water parameters and all good. 1.026 GS, no phosphates or nitrates. No ammonia. PH is 8.2. Mg 1300, Ca 420. Alk 3.6 ml/l. I just checked the water temp. It's 83F up from 79. I think my heater is stuck on. I'll have to get a replacement and a controller. That was next on my list.
Would that little of a change be enough to cause problems?

That growth is looking like a sponge. If I really stare at it at different angles, I can see more structure. It's very transparent. Cool. I get to watch a sponge come into existence.

the clearish ball things look like pineapple sponges to me. They are usually pretty good, can live in low to no light, and polish the water quite well.
