So after my last sub-freezing brewing experience with using garden hoses and my IC outside to chill I decided to build a simple system to chill using water recirculated via a pump through the IC into a cooler. Found a cheap aquarium pump on Amazon and not knowing what I was doing bought it. Attached hose fittings to two lengths of 1/2" ID clear tubing and fired it up. No surprise, it didn't have the juice to move the water.
So I went out and got one of these:http://www.homedepot.com/Building-Materials-Plumbing-Pumps-Utility/h_d1/N-5yc1vZ1xr5Zasgg/R-100178274/h_d2/ProductDisplay?langId=-1&storeId=10051&catalogId=10053
Now I'm not sure if I went overboard or not. There's no question this will move the water through the system but I'm worried it's got too much power for the 1/2" tubing and the chiller coil. I don't want to either 1) burn out the pump motor, or 2) rupture something somewhere else.
Anyone have an opinion they'd care to share or experience with this pump?
