So your 65 G Aqueon tank sprung a leak? And did that happen randomly and without it being side effect of something wrong you did?This tank early last summer sprung a leak well i was at work. Wound up losing 14 fish and a few plants. But i guess the up side is it allowed me to upgrade to my 135 gallon tank with a 40 gallon sump. Currently in the process of getting co2 togther for it.
