I wish I could do more to it. Cost about $50 a month just to maintain properly.
However I’m eying this topper which will put his basking area ABOVE the tank allowing me to fill the tank up fully but the topper is $100 itself and I’d like to glue Astro turf to it too to make it easier on his nails.
i've never kept an aquarium myself but $50 a month for that happy turtle seems worth it (#253 last picture

).
you need the extra water height for easier maintenance or to give your turtle more room?
