Crushed Coral 1 pound bag

Crushed coral is great for fish tanks that need a more alkaline pH. Crushed coral is known for dramatically increasing the buffering capacity of an aquarium, as well as adding to the alkalinity of the tank, raising the tanks pH. The craggy areas in the coral are an ideal place for beneficial bacteria to flourish.

Amazing difference

I have tried tons of options for fixing my PH issues, and i have to say, the crushed coral was the best thing ive used. Shipping was fast. Support to ensure i added it without shocking my fish was excellent and prompt. Lastly 1lb in my 29g was enough to keep my PH which was constantly dropping below 6.0 to staying at a 6.8-7.0 consistently. I definitely recommend using this.

My order shipped super fast and arrived to me sooner than expected. The crushed coral was packed well and worked perfect at raising the Ph in my tank! The code for free shipping sold me! Thank you so much!

Buffer that water y'all

This stuff works, I try to stick to Corey's recommendation of 1 lbs to 10 gallons. Only thing to say is give it a rinse before you add it.
