i have a 29 gal set up with play sand and some hornwort plants. The bottom always collects up dirty dead plant particles and with my common pleco in there, theres always junk on the bottom even after i siphon most the junk out, it gets all dirty again after 24 hrs. any ideas on how to keep it clean. i've seen pictures of other tanks using sand and it always seems soo much cleaner then mine. PLEASE HELP!!!
