So the Tom AL is working good for you? Good, I have 4 of them waiting to autodose on two tanks. Did you have any problems with them so far? I know they arent as precise as a fancy peristaltic pump but at about 1/10th the price they seemed to be a good alternative
. And I thought the whole idea behind EI is that you dont have to be precise, as long as you dosing enough.
Let me see, the AL is rated 3.5G/hr. I'll have to measure the actual flow rate since head loss will reduce this I assume. But my setup will be next to a sump so assuming I get 3g/hr that would translate into a .189L dose (1 minute run time). Would a half EI dose (since will be doing daily) for a 250G tank be to concentrated in about .2L or is this concentration ok? With that concentration and a couple gallon tank I could get several weeks worth of ferts before needing to refill. Is there a recomended concentration? Sorry, I've always dosed dry.
