Hello again r/aquaponics!
Firstly, i’d like to thank you all for your input regarding my bell siphon questions. I think i’ve got enough info now to figure that out to a working state.
Secondly, I’d like to ask if any of you have ever tried using “Hydro Ban” for water sealing a DWC bed?
The idea is to replace the pond liner with this stuff as a good friend of mine has quite a bit of it to spare and he swears by it for sealing wood from water. Now, I’d imagine if the stuff is safe to drink from once set, I could trust it with fish but i’m hoping someone smarter than me will tell me if i’m totally out to lunch on this?
