Florida Crushed Coral Aquarium Gravel, 15 Lbs

I got this to put in a sump in media bags to buffer my freshwater tank's PH. Before the crushed coral, my PH was reading a flat 6.0 and bottomed out after every water change. But now, my tank's PH is holding at a solid 6.4/6.5 which is good because I have an Amazon River Pacu and they like acidic water. NOTE if you're buying this coral to use for this purpose, start with a small media bag, wait a week or so, test the PH, and add a small amount more if need be. Reason being, if you raise the PH too much or too quickly, ammonia becomes more toxic. AND NEVER use baking soda to manage your PH, it's a shock to the system and can kill your fish as non toxic ammonia becomes toxic free ammonia with the rising PH.

Considering this would be at least a $30 purchase at the closest petstore, first and foremost i loved the price. I am setting up a 125 gallon reef (175 including the sump). For my substrate, I chose 100 lbs Black Diamond sand and sprinkled this crushed coral into it, so it looks peppered. Since it's crushed coral, it will help buffer my water while looking awesome. Great product.

I like it a lot for the aquarium (even though I needed like 1% of what comes in this bag). Be aware that you'll need to rinse this A LOT before putting it in the tank. I probably took 15 minutes to do so before I thought it was sufficient.
