Sets up PH quickly but requires A LOT of rinsing

Reviewed in the United States 🇺🇸 on November 12, 2022

The first few rinses of this substrate looked like chai tea. I rinsed each bucket full AT LEAST ten times, but it still didn't rinse clean. I finally put it in the tank and set up my canister filters with very fine cotton-wool type filters and let it run several days prior to re-cleaning the canisters. There is STILL leftover residue, but I assume it will settle down over time. I suppose if I was a tweaker, I could scrub every chip of crushed coral, but I'm not so I won't.

Too fine for me

Reviewed in the United States 🇺🇸 on February 14, 2016

I was trying to get a coarser coral that would not plug my pumps and filter and this unfortunately is not it, Chunks are not as large as it looks in the picture, It took several days for my filter to remove the white "cloud" after adding it to my tank. My sand filter still plugs up daily (about a week now). I'm sure I'll eventually get rid of the fines. Recommendation -- Rinse repeatedly before using!

This looks phenomenal in my cichlid tank. You must thoroughly rinse this substrate before putting it in your tank. It will still cloud up but it will dissipate and settle within a few days.

Awesome product if your looking to raise your ph for african cichlids. I was always told crushed coral would only stabilize ph but i tested 2 tanks 1 with sand 1 with crushed coral tank 1 ph was 7.6 tank 2 was 8.0 which is exactly what i wanted. will need a little rinsing but that is to be expected with pretty much and substrate.

Looks so beautiful. My cichlids love the crushed coral. My cichlids dig like crazy and it doesnt seem like the crushed coral is to sharp. Would recommend to stabilize ph and quality of water. Would buy again.

As good as any other brand out there

Does a good job at buffering my soft water and keeping the ph at a steady 7.5. The pieces are big enough that they don't fall through the mesh bag I put them in. Make sure to rinse it well before putting it in your tank. 40lb at this price is a steal and will last me a lifetime.

The media could not be loaded.

Rinse thoroughly like you should do with anything you put in your tank and you will have no issues. Yes there is debris in it but it's a natural material so that's expected. RINSE THOROUGHLY! No issues and my cichlids love it!

Great product

Worked very well to buffer my RO DI water. I rinsed it only slightly with just one bucket of water and put it in my filter. There is only slight cloudiness in the tank right after adding it.

Great coral substrate

Very attractive product, and you do see small shells here and there which is kind of nice. I bought this product to buffer the water in my 10 gallon tank for my guppies and they are very happy.
