I use Two Part. Very easy to use. I bought their complete kit for $60. It came with the containers, dosing pumps and enough calcium, alkalinity and 2 types of mag to makes 7-8 gallons each.
Sweet thanks I knew a few people use that here and I figured that I would order that because of bulk. How long does the 8g of mix last you on your tanks?
b-ionic is a great product if you dont need the large quantities of the bulk stuff. I also use a 2-part but its from a local company called Natureef. I used to use b-ionic, but this stuff is cheaper and as good or better than b-ionic.
You cant go wrong with any of them.
I've been too lazy to get hubby to install our reactor. I now have 2 other tanks that will need the supplements anyways. That same company sells other stuff too. We did another group order 2 weeks ago and I got enough carbon to last for a while
