Ok this isn't really a "monster" project, but because i'm a poor college student i'm sticking with my ten gallon dwarf puffer tank. I have more than enough filtration, but i really like the concept of a sump. ANYWAYS, I've checked around online, and the cheapest pump i can get is 20 bucks without shipping, and i spotted a $15 power head at walmart that gets 170gph, which is way more than i really need for a ten gallon with a dp and a couple shrimp. Does anyone know if the head height would be large enough to make a diy sump? I'd love to make a mini one before i get my tank i'm planning for in the future.
