First frog tank ever. Probably need help

[deranged chipmunk]

I like your idea of the island tank idea. More a peninsula but something to run with. :-) I'll look into the "weed blocker" stuff.

The filter under the false bottom sounds good to me out of sight out of mind BUT how to get it out to clean it without destroying everything I built every week. Idk lol.

i build a maintenance tunnel into every tank i build so i can access equipment for maintenance or failure. some people design in trap doors for this.

why would you clean your filter every week??
