Seachem Reef Buffer 250gram

It really raised the PH to 8.3. I used this a couple of times because my PH was 8.0 regardless of what I did. So I gave this a try and it raised it to 8.1, then to 8.2 the second time I used this....I waited a week before using it a second time, just to prevent shock. When I used it a 3rd time, it went up to 8.3....a month later, it is still 8.3. PH Saver!! As noted on the description, using this can lower your calcium level. You may have to dose some calcium supplement the next day after using this. Mine went from 460 to 440....but I recommend you test your waters before and after you use this just to be sure.

Perfect Buffer! I now order the KG size
