Help with alkalinity

[sumant19]

Okay, I will be honest. Last time I tested my water parameters was month and half back. Now when I tested it last weekend, all other parameters except alkalinity were fine. My parameters are -

Salinity ---- 1.025
Temperature (F) ---- 75
PH ---- 8.2
Alkalinity (meg/l) ---- 2.1
Ammonia (NH3) ---- 0
Nitrate (NO3) ---- 0
Nitrite (NO2) ---- 0.05
Mg (ppm) ---- 1300
Ca (ppm) ---- 425


As per my test kit, the recommended alkalinity for reef aquariums is between 3-4.8 meg/L.

Any idea how to increase alkalinity without increasing PH too much? Would Kent Pro Buffer work?

Baking soda is the most cost effective way to raise alk. Read through this. http://www.advancedaquarist.com/2004/4/chemistry Use recipe #2 for alkalinity if your pH is ok. This won't effect pH much at all but can drop it a little initially.
