Any recommendations for a peristaltic pump for a calcium reactor? The reactor is a Korallin 1502. I probably need to get roughly 30+/- ml per minute continuous duty. I bought one online that fit the specs, but it is LOUD. It needs to go in my stand in the living room, so LOUD doesn't work. The BRS 50/ml minute dosing pumps are not rated for continuous duty, so they won't work. Just wondering if someone has a specific make/model they can recommend.
