Very good size arogonite with very little rinsing require in a low flow tank. Higher flow tanks will need to rinse but much less than normal. This is a nice substrate that I have in 3 tanks.

I almost didn’t but this because someone left a bad review saying it made the water cloudy and they couldn’t get the water clear. My water was clear almost immediately. I suspect they didn’t properly follow the directions and rinse the gravel first. I took pics and even a video but I don’t see how to upload them. The tank looks beautiful and our fish look pleased.

Great choice for me. Looks good in my fish tank and should help with keeping the hp levels in check

I'm pleased with this product. It looks good and serves a important part of my fish tank

I brought this product about a month ago for my oscar tank. This crushed coral has helped tremendously with keeping my PH stable!

I purchased this as a more natural alternative to painted gravel. The amount times both I and my husband rinsed it out it’s a headache. My water is still murky and took about a day and a whole filter to clear it up. I’d only regret purchase this again if I had salt water fish (raises ph it’s good for them). But considering the Great Barrier Reef diminishes more every year, and more ocean aquatics and animals die and lose their home because of that. I don’t think this is a purchase I could make again in good faith either way.

I purchased 12 bags of this coral at the pet and when I got home found out 5 of the bags had mold in thew

Good ,clean,consistent, coral gravel. I've always used this product for fresh or marine tanks.
