Hey Doug

I agree Bicarbonate will settle out unless you keep it warm. I use Randys 2 part and make 2 gallons at a time i put a small 25 watt heater in my mixxing container and just keep it warm and it does not settle out. Before i added the heater i would have to stir it up to keep it from settling. I use a profilux doser and have for the past year. I love the fact that its so easy to adjust. And that it never needs to be upgraded when you get a bigger system just dose more. Feel free to send me a PM if you have any other questions.

I think you just sold me on a dosing pump... (plus what you said in the PM helped me out too) :mrgreen:

Works well and saves lots of money. Check out the ChemMaster aka littlesilvermax who is a vendor sponsor on here if you are looking for calcium or magnesium.

I use Randys 2 part and I mix 4 litres at a time, then use it till its all done ( I manually dose) and have not had any settling out.

You will be very happy with it Josh. Its an awesome investment.

You can also spread your dosing out with it. I dose about 300 ml of 2 part each day but its done 8 times in 24 hours so there are no spikes.

Like i said before if you have any questions just let me know.
