Well, thank you for all the information, I mean I can't even begin to describe the huge amount of help you guys have been. So once again thank you for the support and the patience you guys been having with me. I guess there is only one way to learn in this hobby, and that's by failing and making so many mistakes. It sucks that it costs the lives of the very animals we enjoy so much, our fault. Nothing else we could say. I just purchased a TMC Fluidized Sand Bed Filter rated for 500 gallons, along with a SunSun HQB - 3500 rated 800 gallons to add a good bio filtration, instead of purchasing another eheim or fluval, I think this would be a good permanent and easy solution for maintaining my tank healthy. Along with proper application of conditioner/ water changes etc. I only paid 150 with shipping for everything, so I didn't break the bank either. What you guys think?
