Well guys, my PH doesn't really seem to be improving yet, but I only have two small baggies of the crushed oyster shells in there. Perhaps I need to add more. I will give it a few weeks.
Anyway, my Pond Matrix came today and I put all 4 liters in. The water went cloudy, but that will clear up. Anyway, I think the scrubbies worked though! Yesterday my ammonia was at .5ppm and I did a 75% water change. Today it is reading zero! Woohoo. I think I am good to go. Now I will use up the rest of my Pond Stability with my Matrix in there and the bacteria growth will just get better.
Or do you think I should dose it for a week or two and save some?
