Anyone know best system for auto dry fert dosing?
Saw the Fishmate thread - mentioned Lifeguard auto feeder. But that looks like it works with one large hopper - so how does it dose the same reliable amount of dry ferts every day?
What do you recommend?

Did you check out the link I pm'd you? That's where the Fishmate for Autodosing is discussed.

Has anyone had any success in utilizing this product for auto dosing of dry ferts?
In the product description it states...
Airline hookup will allow use under even the most humid conditions
Would love to know if this has been tried. For $29.99 to buy this, and the fact that I already have an air pump and tubing ($0 more investment) -I would be willing to guinea pig this. Just wondering if anyone has tried this product.

Bill, there is a bit of discussion at the water pump thread.
I tried Excel, but didn't notice a difference. Possible that the concentration needed to be higher. Omitting KH2PO4 from the NPK mix really helped to prevent the smell that otherwise developed.

Excel works also in place of HCL.

Is there a good thread that discusses best ways to make stable solutions for autodosing? I have heard that people add HCl to the micronutrients to keep things from growing in the bottles and/or provide stability to the chelated iron? Is there any need to add a stabilizer to the NPK solution?
Thanks for your help

You are welcome, thanks for the friendly bump.
Last night I set up some auto test-tube fertilizing for my 135gal garage tank. Took two 6ml and one 3ml oral syringe (N & K and the smaller one for P), filled them with the powders, ziptie around them, and through a suction cup to stick them to the glass.
Just need to monitor a few weeks the rate in which the various powders dissolve. This must be the simplest way to automate fert dosing.

Wow! How I didn't see the before...

|Betowess||Congrats on the sticky. I remember reading somethin Sergio said about getting the flow at the rated amount if the peristatic is set for full output. But if you opt for a variable flow unit, the ouput was not as consistent when setting the speeds. So the long and short, don't order a variable output, just use a timer or dilution to get one's desired ferts in the tank and use a one speed (flow) unit.|

Hey, great work WP! It's too late... but I still want to throw in a vote for sticky too! Really!
This is an outstanding starting point for someone considering autodosing. And for those of us that is has been successful for, that can make this hobby a whole lot easier.

Thanx! I haven't received my pumps yet, but I did just pick up some medical grade 02 tubing, bubble counters, tank and a couple of regulators from a landlord that rents the place behind me--all Free. Now I just need a prescription to get the tanks filled. Anyway! the 02 tubing looks like a smaller diameter, so it may work. Don't really like the fact that its clear, but we'll see how it goes.
The solution can be diluted if it pumps too much or too little by adjusting the cycle time. In the end--its all about getting x-amount into the tank. Mine are estimated to run 1.5ml/min. At 0.25ml/min I think You've got a large margin of error!

I had some Norprene-like tubing from a friendly fellow member, as well as the usual air "Mini tubing". It fits alright, since there is no pressure involved it doesn't have to be extremely tight.
Diluting would be necessary if they pump too much, that's correct. I want to dose concentrated solutions, I think they don't degrade as fast as diluted ones.
