Hi, Maxtegroom,
I'm pretty new to this community myself - I hope it is as much help to you as it has been to me.
One thing I noticed about your set-up (which is pretty good already, btw) is your filter. I didn't learn about filters until way late in the game, and so I thought I'd pass on some info to you while you're just getting started.
I thought it was a lot to digest myself, so I'll just drop some stuff here to start your reading. Here are some helpful links:
Types of filtrationYour current filter is handling the "chemical" part of the filtration, and is doing an OK-ish job at the "mechanical", but is not helping a lot with the "biological". A canister filter (I have
Eheim 2215s in my tanks, for example) are best for turtle tanks.
Water parametersA quick cheat sheet about the parameters you should be measuring in your water
API Test KitHow to measure said parameters
Pretty sure there are more reading resources on this topic too right here on this forum, if you browse around.
Regards,
