main thing why these shine is the cost factor. it does the same thing for less. he used regular sponges compared to the stringy pot scrubbers that are recommended. i couldnt find any pot scrubbers and used those shower foam things that look like stringy pot scrubbers. its not as pretty but so what.
i would take pictures of mine but i need more light.
I dont think its more efficiant, maybe cost wise but yea its probly not as good as a proffessionally made one. Good build but its not going to be any better than other ones, its a sump they are all effective.
ok, ok... if you built one similar then maybe it wont work as well but mine works better than all my other sumps. watever.. i just wanted to post my sump pics!
