I'm using this pump: http://www.reefdosingpumps.com/products/sentry.html
Can the BRS or Cole pump work with an autotopoff?
Even though the Reef Dosing Pump claims "silent" operation, I can still hear it from about 6-8 ft away. And when the power goes out, I have to reset the dosing rate in order for it to work again (no backup battery). Looks like the BRS will work when the power is restored since it doesn't have a cpu built-in.
Also, is a 2 roller (BRS) really better than a 4 roller setup?
