Crushed Coral Problems?

[dougdoug99]

Hi everyone,

I've started cycling my tank and without knowing how bad it is I've used some crushed coral. The tank is 125g 4x2x2. I have about 4 bags of Hagen Geosystem fine substrate and then I added 1 bag that was 20-30 lbs of crushed coral. What sort of problems am I looking at by having this CC? It's ultra fine, I'd think it's sand if I didn't know better. Am I still able to have a cleanup crew and will I have problems with my other fish? The plan is a community FOWLR tank. It will have snails/crabs/starfish/small community fish.

I could scoop some of it out but it's mixed in with my other substrate so I wouldn't be able to get all of it.

Thanks!

IME only the large chunkier if you will crushed coral is a problem. If it is sand sized you should be ok. I hope you know what I am talking about. The bad stuff almost looks like little branchy rocks.

Thanks. Mine is ultra fine. I wouldn't know it from sand.
