I know you can get cement tinted. Would you coat the thing in silicone, or just let it be? I’ve heard they raise the ph awfully when you don’t clear coat them! Great stuff is spray foam right? Sounds like an awesome project!

so both drylok/cement and a clear coat of drylok? and yeah great stuff is spray foam, i just don’t know if i’d have to use the kind i already have or the pond kind

If it dries inert there isn’t so much need for a clear coat. I am not familiar with DryLok and can’t find online if it dries inert. If the foam dries inert and is non toxic you should be able to use it! We used the pond foam to seal some rocks in our koi pond, so I know that one should be fish safe!

Glad I could help! You also don't want the concrete you choose to have any additives, such as mold prevention and such.
