I run 4 aqualifter pumps so I can dose Ca & Alk into two separate tanks. Two timers set to run for 1 minute intervals on 1.5 hour intervals. Each dripline ends with an irrigation needle valve for drip control. Think I spent $15 each for the aqualifters. Everything else I already had.
The driprate is way more steady than I ever thought it would be. It's working out well, in fact, I pretty much have the needlewheel valves open all the way. I haven't tested yet this week to see where my Ca is at but I was debating switching the 1 minute durations to 2 minutes.
