Really the only long term solution as your turtle grows is having a larger volume of water (bigger tank, large plastic tub, etc). If your turtle is 7 inches the minimum tank should be around 70 gallons and that's using it filled to the top with an above tank basking area. Go bigger to accommodate for growth. Get a 100 gallon or more. I found great deals on Craigslist when I purchased my tanks. On Craigslist you just need to be patient, check often, and respond to the great deals really quickly.
