Ps, everything is made out to be cheap but added up even the simplest setup can cost alot. You will be glad you spent out tho once you have big a healthy turtle and fish. You will love watching the turtle explore, great to watch them discovering how big their shell is when they are trying to squeeze through gaps, many times mine has got stuck and has had to go wild to get free, exp when they are small it's funny.
I'd spend out again on mine, he's so worth it.
