it isssssss ... lmao , were gunna try to go for a natural feel , the only form of filtration is the skimmer , but ima see if i can put some bio/mechanical media in the skimmer box as well , but we wanna try letting nature do its job , the skimmer and water fall will serve as more of circulation , live plants and such will be our filters mostly , boyfriend wants to add bluegill sunfish and creek chubs in it , but not until everythings quarantined to make sure they dont get my babies sick xD , but the edges are actually pretty steep , i dont see the turtles actually crawling out of it , but basking areas will be put in place and such . its got a long way to go , but ill keep you updated along the ride !
