I love this product! Bought 4 bags and the color is consistent between them. There is a few off color pieces in the mix but not many and to me it wasn't a problem to just press them in and bury them. I have never used this. It comes with a tad bit of water in the bag. It claims that it has nutrients. I used it as a surface layer but under that I did dirt mixed with sand, followed by 1 inch of sand and about 3 inches of this stuff. It worked out well and now I have a very deep substrate. This is basically gravel but is not painted and I am sure my plants will love this. Very nice to look at. I didn't bother checking the PH since it is in a new tank and you really should wait a while before adding fish. I expected it to make the water decently cloudy but it didn't hardly change the water color at all. Maybe just a little bit. Nothing to worry about. And I did not rinse it at all. Much better than your standard gravel which for sure you need to rinse. I spent a lot of time searching for the right gravel and I am glad I bought this. Well packaged too. No leaks in the bag. It is kind of pricey though. That is why I used play sand under it and packed it down. It of course needed to be rinsed first. This product sets nicely on top of the sand under it and doesn't sink in much. You can easily save some money by just using this to cap off some sand. If you use lava rock under it then the heavier rocks will eventually work it's way to the surface so you probably don't want to do that.

Not so sure how it grows plants yet, but it was super easy to plant them in this stuff. just to let you know, it is just tiny crushed lava rocks, not soil. its inert substrate. its definitely a cheaper option, but you will have to use root tabs if you don't use a layer of aqua soil. it didn't cloud my water, which is nice, don't rinse it, because it comes with a liquid that's apparently full of beneficial bacteria. the color is nice, i got the black. you can get the 18lb for a 20 gallon long. i have about half an inch to an inch layer in the front and about 4 inches in some places near the back with left over. unless you want evenly 3 inches or something, 18 lb. should be enough. i will mention that i used a sand cap, and some of the sand has sifted through the gravel, but only time will tell how it holds up.

I am new to planted tanks. This is my very first attempt. I had a goldfish (Gunsmoke) as a dorm pet in college and then some guppies. I recently got a betta (Rupert Pad Kee Mao) for my desk at work, but he will need a home in my home when I need to be out of the office for extended periods. So I started research to make him a vaca home that rules. I spotted CaribSea Eco-Complete 20-Pound Planted Aquarium, Black, just because I wanted black/natural substrate and started to read reviews. Honestly, they almost scared me away from this, but so happy I went with my gut. This stuff is amazing. Mind you I have a 5 gallon and it was daunting getting 20 lbs. of substrate. I worried that only using part would be a total mess. But guess what, it is fantastic. You are going to make a mess with any substrate, just head to your tub and work there. Placing into the tank it was NASTY! So nasty that I thought about all the reviews to rinse it, second guessing and extremely worried about double work. No worries though, seriously DO NOT RINSE this substrate and read the directions especially when adding to an established tank. My little tank was almost clear an hour after running the filter. By the next day the tank was crystal clear. Planting day (Red Cabomba, Water Sprite, Banana Plant, Bacopa and Java Moss) it was so clean (with a few floaties). Planting did kick up a bit, but not as much as I would have thought. It is now day four and the plants, even after all the stress I put them through, are thriving. I have not run chemistry on this tank yet, but will in a few days once it balances itself out (I don't want to freak myself into a tizzy looking at readings). I will probably get another tank (do not tell my husband) to use what is left. It looks fantastic, very natural with bits of rose and tan. I'll try to get back and update when Rupert moves into his penthouse in the next month. Update: It has been over a year and I still love this substrate. I did have a large die-off of plants due to being lazy and not caring for my plants as I should. But both Rupert (he never did return to my office) and an Anubias that was added after the original review was posted are thriving. The other plants (micro-sword, Bacopa and Wisteria) after the initial die-off are also doing really well Yeah, I have had a Petco Betta for over a year and he looks great swimming over CaribSea Eco-Complete 20-Pound Planted Aquarium, Black.

I use about two inches of it beneath soil and a cap of sand and have experienced excellent plant growth with this setup. It’s an inert substrate so no nutrients like soil but over time it does absorb nutrients from the water column, which gets redistributed to plant roots as nutrients. Unlike other plants substrates, it doesn’t need to be replaced over time. It retains the ability to feed plants for years, which is a plus, imo. It’s packed in water with vital bacteria in it so it tends to cloud water during the first week or two. It’s a good idea to do several 50% water changes during this time to balance out your tank. After a few weeks, the cloudiness will clear Packaged arrived quickly and in good condition
