I quickly drew up my idea of a cheap sump layout on microsoft paint. I simply want to move my skimmer and heater off the back of my tank and add more volume to increase my safty margin . I have a 20 gallon high tank that fits nicely in the bottom of my stand, I figure if i put a siphon tube down from my tank to the 20 gallon, put my skimmer heater and some rock and sand down there also , then use a strong powerhead to pump the water back up to the main tank it would meet all my needs . Does anyone see any problems with this ? or any better ideas? i cant spend alot of money if any .
