My son and I were very excited to get a python since people seem to really love them, but when we tried it this weekend it took a REALLY long time to drain our little 20 gallon tank. It filled it up in a snap, but draining was really slow. Are we doing something wrong? I had to get a 50ft, since the 25ft was going to be a bit short. Is it too long to maintain the suction?
I'd appreciate any suggestions. Thanks.
