Review: GOOD WATER - 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
Review: perfect product - 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.

### ⭐⭐⭐⭐⭐ Worth it
*by A***R on 20 April 2025*

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
