Give it a few weeks, drain it and check every side etc. If no leaks, then your set. BUT imo I would like to see you test it out on a LARGE tank. Im still iffy about that since the guy built a 150gallon and there was alot more pressure going on.
Ah,ok thats what i plan to do.Does it take much material off the hardiboard?canufeelme;1768986; said:i cut hardiboard with a grinder that has a diamond blade on it.
