Basically I have a lot of trouble keeping my ph and alk up due to many reasons (mainly not enough time to invest). Anyway I have been using "aquarium systems" seabuffer along with salifert Ca when I notice it is low (all the time). I saw at Target they sell alk booster's along with ph boosters for use in swimming pools. I noticed the alk booster lists the same basic ingrediant as the seabuffer "sodium bicarbonate". Since this stuff is a lot cheaper then seabuffer I thought about using it, but I am worried it may have other chemicals that would damage my reef. What do you think? Have you heard anyone try this stuff. If it is the same stuff and it is a lot cheaper that would be great. Maybe it's too good to be true. Any help in this matter would be appreciated. I know in the near future I plan on going to Kalk drip but that is going to be difficult to setup due to my tank's location and design. Thanks in advance, Scott
