There seems to cobwebs growing on my sand and crushed coral bottom wondering should Ijust vacuum it up or is it some kinda good for my tank. I know Ishould get rid of the crushed coral I've been doing it slowly. Wanna get a daggonet gobie should Ileave half of crushed coral in there for coipods to reproduce?

If you want to get rid of the crushed coral, don't do it slowly, you will only stir up detris that has settled. How long has your tank been running and how deep is the crushed coral? Could cause some serious issues depending on how deep it is.

I would pull all the LR out, catch all the fish, drain the tank, remove the crushed coral all at once, replace with sand you want, replace LR and fish with at least 50% of the water that was in the tank when you drained it and leave it be after that.

As for the cob webs, most likely red slime algae or diatoms.

i would just dump the sand you want on top of the crushed coral win win

Hoping to come across a bow front drilled tank for a swap somehow. Then Iwill add and take out sand Iwant.

a picture says a thousand words..... these cobwebs could be from a number of creatures living in the sand/crushed coral. Likely a spaghetti worm spewing goo around in the sand. Reef grade sand would be best for a dragonette in a very established tank with a refugeum and a lot of pourous liverock.

Can you find a start point for the "cobwebs"? Every time I have heard that description used, it has been a vermetid snail. Google them and see if that's what it looks like.. They LITERALLY look like cobweb strings lol.

Gonna google it now. Just had a out break of tthe slug finger nail snail been sucking them off glass and tthrowing in pond

It was. A vermetid snail. Thanks for the info kinda neat creature might just let tank run and maybe hermit will take care of it.
