In March of 2014 I was having trouble with the 2 pumps on my Alpha Cone 300 and you were able to sell me 2 new engine blocks that repaired the problems.
I am once again having a problem with one of the replacement pumps. It continuously shuts down. When I pull the electrical plug and re plug it to the electricity it starts up and runs for a few hours and the impeller stops and I have to unplug it and re plug it to get it going again.
I bought your old 75gal aquarium off you a few years back. Its taken a while to be able to install it, but i remember you wanting to see it.
I created a journal website for the build and installation of it, so feel free to take a look.
