hey I was wondering if this silicone I used to reseal my tank can't be used. My tank has been setup since December. I had a cyano issue because of some pukani I believe were leaching phosphates. Took them out and used chemi clean twice and so far so good. I have a couple of fish (pair of clowns, chromis, yellow tang, sail fin and flame angel) that are doing fine but I'm having trouble keeping snails but crabs are fine. I have recently read that silicone 2 causes crashes etc. and would like to know if maybe it's the silicone. I'm trying to identify the problem. Any input is appreciated, thanks!
