Stupid dosing pump questions

[fishytime]

Ok, so Ive been thinking of picking up a profilux 4 pump dosing unit. I have this lingering question in my head that I thought I would run by you all. I was thinking about dosing two part Ca and mg (not sure about the 4th pump?) with the unit. My question is this....every bottle of stuff I manually dose says to "shake well before using"....how do you get around this? Do you have to shake your containers of additives every day or something? Because if thats the case, and I have the bottles of stuff in my hand to shake them then I might as well do the dosing myself....no?

I'm jumping in on this because I'm curious too.

I was thinking or guessing though, that maybe folks either use air pumps and bubblers in the mix, or maybe powerheads to keep it all mixed up?

One could get something like a test-tube rocker... or make stirrers, and have them draw from there? I mean it wouldnt be hard at all to make a rocker. I think this could work? Im going to be making my own stirrers for the phyto/zooplankton/rotifer reactors im going to set up eventually.

i use the Randy's 2 part recipe. There is no need to mix any of the solutions again. Once it is dissolved, it wont percipitate out. I don't know about the commercial mixes, seems like a waste of money when you compare costs to getting the chemicals from chem master or bulkreef and mixing your own.

^ get the the same idea from Aqua-Digitals write ups on the Balling Method, the salts stay in solution. Also as Ephraim says, get your dry chemicals in bulk to make your own DIY solutions.

Not trying to be ignorant or start something but, sodium bicarbonate is sodium bicarbonate....whether I buy it in a bottle or in a bag, it will still settle out and need to be mixed....correct me if I am wrong. I dont get why something I make myself from the same chemicals would behave any differently from something that is pre-made.

I use Randy's 2 part as well. I would guess that the majority of people running dosing pumps do not use commercial prepared CA or ALK products
