I have been doing brs two part dosing for a while now and wanted to see opinions on getting 2 aqua lifters that were set to timers to come on/off for a set time/dose each day instead of buying something that would cost 100+. Thanks!
+1, or go with a Bubble Magus. While the aqualifter pumps are great little pumps, I'm not sure how accurate you can get with them especially with just an outlet timer. Also, they can't work against any sizable head pressure for an extended period IME. I've tried using them in that capacity before only to check a week later and find that they are no longer working.
