I will be opening a thread in the filtration section to show my Undergravel-Overflow-Input with jet-return-push Flushing system, which I believe is the way to go for fish tanks with arowanas and discus, if you're tired of looking at bare bottom tanks and don't want to do massive WC and lazy to vacuum/clean your fish tank.
Thanks a lot guys!! Took me almost 6 months to finish my fish tank, I only work on them on weekends and sometimes not even. If it were just a fishtank and stand with out the background and my filtration system I would have been done in maybe 8 weekends. The background and filter system took the bulk of the "build". This fish tank cost me about $3,500 including everything - pumps, heaters, walls around it......... The only expensive part of this fish tank is the front glass $500. The rest are cheap but they all add up preety quick. TAnk dimension is 8'L 4'W 3'H (outside dimensions).
