man, ikr! That basking pad is so annoying! I hope to someday build a pond for the turtles outside so i won't have to deal with them in a tank anymore. I can never make the turtle tank look nice (except right after cleaning day) because he loves to "re-decorate" his living space. He's not a good decorator.
Making a pond can be involved but I will say it is well worth it. The reason it was tricky for me was I needed to clear out the pond site(3 boxwood bushes and ALOT of mulch), and I hit a couple pipes on the way down that needed to be moved. If it weren't for the initial clearing of the bushes and the pipes, the pond would've been a breeze to build. Only 150 gallons so it wasn't tough to dig at all. Threw a liner in there with some play sand from home depot, used a couple rocks to weigh it down, the filled it with a garden hose. I planted hornwort and anarchis, although the hornwort didn't do too well. The anarchis did a little too well and ended up dominating the pond, lol. I wish it had been a balance of the two but I dont really care. I also introduced a couple giant trapdoor snails to the pond. They helped control the algae and bred nicely. Then I put a couple catfish and Sunfish in there. I didn't filter it at all, or aerate it for that matter. Never fed the fish, the pond created its own food for the fish. Insect larvae and other stuff. 1 year later i disassemble the pond to move. I caught 2 catfish and a sunfish. Oh, and I also had this bullfrog in there. He used to sit on a log floating in the pond. I saw him from the kitchen window every day. It was fun. So yes, having a pond is very rewarding. My next pond is probably going to be a little bigger, and have some turtles too.
