The bag has been rebranded and now it’s extremely large substrate instead of crushed like in the photo here. What you receive will look entirely different than what is picture including the bag and contents. Highly disappointed in petco for using old photos of old stock when it isn’t the same anymore.

I’ve used this CaribSea for 42 years in different tanks. Yes it is a little gravely, but the crushed coral, snail shells, aragonite and fossils. The combination of this mix is awesome for saltwater and fresh. I’ve used it in both. Keeps ph and alkalinity, magnesium levels ok. Rinse but not to much your water will be cloudy. It’s the crushed aragonite floating it will settle. Actually that milky substance in your tank is natural and healthy for the system. It will help with calcium levels and feed beneficial bacteria through the digestive system. Everything eats something in the water world. Very good product one tank is 17 years old with Caribsea crushed coral still looks good and still breaking down feeding the tank calcium, magnesium, and ph never changes. I’ve gone 4 years and not a single water change, only top off. 33 gal. Show tank. Fish, coral, live rock and this crushed coral make up so many places for beneficial bacteria to grow. I haven’t added anything new to this tank for 4 years just let it keep cycling and keep filtration clean.

I thought this was going to be the size of sand but it’s really the size of gravel. I had to return it wrong stuff

Works like it should, our African Mbuna live it. I rinsed it several times it still clouded up the tank cleared up nice in a day or two.

Helped increase my PH in a Mbuna african cichlid tank. The Nitrates are doing better also. The fish seem to be more active and can move the small granules by mouth for their territorial spots while mating.

I have florida crushed coral is that good for freshwater I have 90 gallon I have african cichlids bala shark and Jack demspey pleo aglea eater clown loaches jewel cichild red blood dragon peacock feather catfish yoyo loaches rainbow shark os that for Florida crushed coral

great product, but it requires alot of washing and will make your water cloudy at first. after a couple of days, a good filter will take care of the cloudy water.

Rinse it even though it says pre rinsed on the bag,it WILL cloud your water and take hours to clear up
