output of fertilizer auto doser. How do you guys do it?

[JackBlasto]

So any of you guys using an autodoser for your ferts. How do you place your output tubing? Do you dangle it into the water or let the output tube hang above the water so it drips in from above? I've had two thoughts about this... above the water seems to allow the liquid to crust up a little as it dries a little and awaits it's next day dosing.. Allowing the tube to physically be underwater I'm concerned as the water rises, falls, it actually takes more of the fert dose out of the tubing so it's not a precise amount being dispensed. Right now I just have them dangled into the water but I was wondering what anyone else does? Thanks.

Well, for starters, how are you autodosing? Large volumes or small volumes?

 

[JackBlasto]

I would assume 10 ml daily is considered small dosing. I do PPS pro method and am dosing a 100 gallon tank.

Are you using a DIY autodoser or a peristaltic pump?
