Simple method of dosing alk?

[mseepman]

It's interesting to see where your CAL is at. Biosea is an excellent salt (my favorite behind their Marine Environment version) but I recently decided to try Reefer's best and my CAL has just dropped through the bottom while my ALK has stayed fairly high.

I believe salt does make a big difference on your dosing regime so make sure you watch both numbers carefully so one doesn't get out of wack more quickly than you realize.

If you go to Walmart, they sell TDS meters for $15 in the Auto/RV section so that you can regularly check your RO water.
