I originally did the peat moss - sand 50/50 mixture, and although it was great at simulating natural environment, it clogged the crap outta my filter. It was a total nightmare! Everytime I came home my more than powerful enough filter was clogged with peat moss that had been drug into the water and expanded. When I opened the filter it looked like there was no components or media- just mud. Like a bucket of mud sludge. It was months of struggling with water clarity, and PH.
So I've recently switched over my land media to just plain play sand and I can't tell you how much better it is. I'm happy, turtle is happy and the filter is happy. She's been basking more, and her water has been crystal clear- much better in my opinion. Don't make the same mistakes I did.
