I'm currently having a 3D Galaxy WC kit I by Gigabyte. Anyway, the water tank started to break a parts and the pump is made a lot of loud noises, also it seems to be doesn't pump enough to make the water flow smooth. I took it a part and tried to open the pump to see what's happened, but I couldn't open the whole thing. Anway, I bought the Eheim 1250 from the WC guide. I tried to buy a relay kit from cooltechnica, but they don't have it right now. So should I return the Eheim and get DD 12vdc pump or just run Eheim with 120v and wait until the relay kit is available?
