Sluuuder Oh okay! Hmm, well guess ill have to hold off on getting an automated one then. Thanks for the help!!!

shift I have seen cheap ones that use a motor to squeeze down the pump on bottles but that isn't very consistent.
Dousing pumps are 15-20 on the interwebs and is really the most expensive part. It will prob cost 50-80 for a 1-3 pump system in the end

Sluuuder Okay so its alot more than just the $15 for the water pump? Supposedly on the front page it says soemthing about just needing a water pump.

Sluuuder Where do you buy the water pump for $15? I'm looking on ebay and none of them have outlet hookups. Will I have to rig it with some positive and negative wire or something? Could someone send me a link of where to buy the pump for it? thanks!!!

calihawker The funny thing is, it would be more expensive if I had to buy a couple pumps. I have corny kegs, gas cylinders and regulators up the wazoo from years of brewing.
I did read your posts on leaving out the KH2P04 and I figured worst case I mix them seperate and dose from 2 containers.
I don't recall reading anywhere that the chemicals seperate and require constant mixing. That would be an issue with the setup I'm planning.

Thanks a lot for these awesome threads.

Wasserpest Looks like you are going to set up a very expensive system, when you can do the same with a cheap pump and a regular 5gal bucket. Unless you have those parts laying around anyway. The pump also mixes up the solution each time it doses.

I can't answer your question wrt the oxygen, but I noticed that when I only mix KNO3, K2SO4 and maybe MgSO4 I can go for 4 weeks without mold growing or strange smells developing.

calihawker I can see this threads been inactive for a while but after reading it several times I'm ready to build my autodosing system and I have an idea that has not been discussed. I have a large tank (300 gallons) and I want to mix enough for at least 4 weeks. My idea is to use a 5 gallon cornelius keg (soda keg we use for brewing) and hook up a regulator with a solenoid controlled by a timer. The advantage of having a completely sealed container is that I can push the liquid out with an inert gas (nitrogen). The question is, when mixing and storing the solution, what effect does oxygen have on the degradation/mold growth and can that be countered by purging the container of oxygen?

I'll be using the keg idea regardless as I have a large tank to dose.

vidiots I think reguardless of the form of concentrated Iron in liquid form you use you are probably going to get atleast a yellowish staining of your reservoir or bottle over time, and possibly a buildup of of some sediment overtime in your reservior and plumbing.

I think the only way to completely avoid that would be dry dosing your FE & traces.

Even the bottles of flourish get crusty around the rim eventally.

Martin An aquaintance of mine uses a bit of Nitric acid(HNO3) to prevent P & Iron messing with eachother.

Dosing full strength Flourish works better for me.
Just curious, did you ever try HCL? Because I've heard it stops mold in CSM+B?

Wasserpest Yes, that's it. In this post I made a little drawing of how I have it set up. Only drawback is that P would need to be done separately.

And that is with the timer/liquid doser setup in your other thread? I'm curious because Donald Byrd and Rosie Hawks said they didn't have a problem, but that was a while ago?
