It's not what we'd call a positive displacement pump. Back pressure in the lines would definitely affect the output. If the pressure in the lines could be deemed constant then some experimentation could reveal if this would work consistently.

Obviously a peristaltic pump is much better on all fronts except for cost.

I constantly think of getting a dosing system for my ferts. But my issue with using a dosing system is that everytime I do dose I find the need to shake up my solutions due to settling. By use of a dosing system the solution will not be shaken which will lead me to believe that the dose will not be consistant in concentration.

hmm, if you find any settlement in your solution, that means you tried to dissolve too much in the amount of water.

Not knowing anything about IV drips, where would you put it? Don't IV drips need to be higher than the destination of the drip?

you can keep it agitated by keeping an airstone going in the resevoir.

Sure.....

The pump wasn't suitable for my needs because of where I wanted to locate the pump under the stand. Locating the pump under the stand created too much head pressure rendering the pump ineffective. If the pump and reservoir could be located somewhere equal to the tank height (+ or -) this would have worked out great. 20" of head pressure is about all this little pump can take.

Marcel, so something like into a sump under the stand would have worked?

Actually No, not really. Ideally the resevoir should be set next to or behind the tank because the flow rate drops off dramatically as it drops down. That's why I scrapped the idea ,because I didn't want to see the resevoir.

Maybe one of those hang on the back refugiums would work perfectly for this pump.

Sean, if you wanna borrow the pump to experiment with it, I can send it over to ya. I'm so swamped at work, that I don't have time to mess with it right now. Send me a PM.

Marcel

Wouldn't this oxidize the nutrients?

My thought would be to have the peristaltic pump and an air pump come on at the same time (via timer). The air stone will mix up the solution in a few seconds and the peristaltic pump would get homogenous solution after the first few seconds. If it's on for more than a few minutes, the first little bit sucked up wouldn't be a big deal.

Is there a problem with N, P, K and micro nutrients doing funny things together and oxidizing? I am planning on using Greg Watson style nutrients (basic PMDD stuff).

P reacts with iron and possibly other micro nutrients. As far as I know, P seems to be the only nutrient that should be dosed seperately.

But why does everyone recommend using an airstone in their dosing container. Wouldn't that lead to oxidizing?

Thanks. I'll try and track down some multi-headed peristaltic pumps to get the N, P, K and micros in different bottles. My stand is going to be full.
