HCA: Hermit Crab Association

Since we are all doing the social distance thing i was thinking about doing a deep clean to the tank. I still have one crab that likes to burry himself on and off. I haven’t done a deep clean maybe in a year. I have added new stuff but, that is about it.

I have a 29gl tank. I was wondering on how much eco earth to put in the tank and how many bricks i needed?? As of right now i have 1 brick. I know that i would need to buy more online. I just don’t know how much i need.

If you don't have an emergency like a bacterial bloom or flood, there really isn't any need to completely change out the sub.

I may be one of the few that use all Eco earth in my tank. I have a 29L tank and i use 6 bricks. That gives you about 6 to 6 1/2 inches of depth around the whole tank. Its best to buy the ones that come in a pack of 3. Just get 2 of those.
