I've been using Randy's 2 part since I started the hobby. I use Dupont Calcium Hardness Increaser for swimming pools from Lowes and Arm & Hammer baking soda. My dosing pumps and an ACJR dose 330ml of each a day.

What kind of pumps are those? How much are the replacement tubes and do you need to replace often? I can attest to the beauty of Bernie's tank. It is a spectacle!

Got the pumps from aptinstruments.com. This is the same manufacturer as the Drew's Doser Peristalic Dosing pump from bulkreefsupply.com. Replacement tubes are about $5. I have'nt had to replace the tubes yet. The manufacturer recommends replacing the tubes every 1 to 2 years depending on use.
