The natural way to avoid chemicals and baking soda to raise pH

My pH went from a steady 6.0 to 7.0 in a week. I have a 70 gallon/Fluval 406 tank and use this product with a media bag. I just slip the bag into one of the top media compartments and add more as I go. I would take the advice of the reviewers here. - Use a small amount at first, then gradually add more to reach the desired pH level. - Rinse thoroughly before use. to avoid a cloudy tank.

Great addition to live sand for a reef aquarium!

Excellent product. Helps bio-filter your aquarium and keep your reef tank looking natural. Just make sure you rinse it well with a colander before adding it to the aquarium. Some of the crushed coral will crumble into dust during shipping and will fog up your aquarium for days if you don't wash them off first. I added it to my live sand bag to help with cycling in the new aquarium and to provide different particle sizes for my bottom inversions and fish.

  • Very good price
  • Can't remember

Works like magic. I added about 3 5 ounce cups to my 20 gallon tank and overnight my PH went from 6.4 to 7.2! So the product deserves a 5+ rating, but I can't give it the rating it deserves because the resulting color is totally different from the picture. since my gravel is beige/light brown I bought this bag because the color on the picture looks like beige/light brown but it came more like white/grey hence the 2 star deduction.

  • Stylish and modern design
  • Very expensive

Works well well for gravel

I have this to put in media bags in the sump to buffer the pH of my fresh water tank. Before crushed coral my PH was around 6.0 and dropped after every water change. But now my tank PH is holding a solid 6.4/6.5 which is good because I have Revain River Pacu and they like acidic water. A NOTICE. If purchasing this coral for this purpose, start with a small media pack, wait a week or so, check the pH and add a small amount more if needed. This is because if you increase the PH too much or too…

  • Nice packaging

Works great as an alkaline buffer!

This crushed coral is great for balancing water hardness and therefore pH. I sprinkled a very thin layer on my white gravel. Shredded Coral is slightly darker than white (it has a very slight pink tinge depending on the light), but makes no noticeable difference. He buffered my pool by adding calcium carbonate to the water and the kH has been good ever since. The pH was constant at 6.5-7.0. I assume the more you put in the tank the higher the kH and therefore the pH, but for my purposes 6.5-7…

Raised the PH in my tank from 6.0 to 7.5.

We have a 37 gallon aquarium with native fish. mostly mollies. In the three years that we have had an aquarium, the PH has always been on the lower end of the spectrum at 6.0. After a while I read that the ideal pH for most native fish is around 7.0 while mollies are closer to 7.5. After researching this topic (how to raise pH), I found three natural solutions: 1) change water more often, 2) feed less, and 3) coral/shells. When I opened this 15 pound bag I found that most of the crushed coral…

The good news is that it is very nice with all of them.

The good news is that he's very pretty with all those tiny shells. I already mixed it into a bag of sand in my cichlid tank. The bad news is if I had to buy it again I probably wouldn't. I would probably just walk all the sand. Firstly, I'm not entirely sure how much of this is actual crushed coral. There's tons of seashells mixed in and what appears to be small pieces of gravel. There were also small pieces of black material and some dark brown ones that looked like dried shredded leaves that…

  • Awesome to me
  • Hard to say
