Crushed coral, carib sea geo-marine PH, KH buffer. 150g pack with free media bag.

FOUND SERVICE SLOW,I HAVE ORANDO GOLD FISH SO WATER IN TANK HAS TO BE 7-2 TO 7-6 pH FOR TO HAVE GOOD HEALTHY FISH I FIND CORAL VERY GOOD,THANK YOU

Brilliant, just what I needed to raise the PH in my aquarium, perfect, came with a little bag, put it inside my external filter on top of everything else, and boom, simple as that, now to wait for a while for the PH to rise. See, I have bogwood in my aquarium as well, that's why the PH was dropping as it rots, it lowers the PH, and my water is soft as well, so I just needed to up the PH slighly, so i didn't put all the coral in the bag at once ill keep an eye on the PH over the comming weeks as i have an electric PH tester wich i reccomed you get if you havent got one.

Great for stabilizing pH. Any tanks with an unstable pH most likely have low buffering and kH. This will naturally raise it but use with caution - too much can also raise pH overtime so remove it once you’re happy. I personally only use around 10-20g of it in my tanks filter and it’s a big tank since I don’t want an extreme jump as my tanks pH is around 6.8. It’s been stable the past 3 weeks I’m very happy. Worth it!! Cute bag it comes with too

Does exactly what is expected
