Hi all, I currently have a 32 gallon Biocube and it’s been going great so I upgraded my tank to a 90 gallon with a 30 gallon sump. I bought this tank off of someone on Facebook market place and he gave me all of his previously used now dried rock. I was concerned with putting this in because I see it has dried up worms on the sides which are now stuck to the rock. I was wondering if this rock is still good to put into this tank as I really do not want any pests or other unwanted things in my tank. Any advice is much appreciated thank you!
