Product description

Size:20 Pound | Color:black

New formula for enhanced root development. Why does Eco-Complete planted aquarium substrate outperform other products? For the same reason that Hawaii, Bali and Costa Rica are famous for lush, exuberant plant growth. The secret lies in rich basaltic volcanic soil which contains iron, calcium, magnesium, potassium, sulfur plus over 25 other elements to nourish your aquatic plants. Eco-Complete Planted Aquarium Substrate is mineralogically and biologically complete, giving you luxuriant aquatic plant growth without nuisance algae. Iron rich Eco-Complete eliminates the need for laterite. No artificial dyes, paints, or chemical coatings. Eco-Complete has highly porous spherical grains for optimum diffusion performance and contains live Heterotrophic bacteria to rapidly convert fish waste into natural food for your aquatic plants. It establishes a natural biological balance which makes cycling a new aquarium faster and safer.

Awesome live plant gravel!

ByBiancaon December 1, 2014

Size: 20 PoundColor: blackVerified Purchase

I bought 2 bags for my 25 gallon tank which was a good amount. This was an established fish tank before I put this new gravel in. I changed the gravel completely to this new stuff in one day. My water was cloudy for a few hours and non of my fish died. I did keep as much of my original water as I could. I heard that this gravel was "stinky" but I didn't smell anything at all and the way these were packaged was amazing.

I won't be buying "normal" gravel ever again. Very happy with this aquarium gravel!

ByNick Mnemonicon July 1, 2015

Size: 20 PoundColor: blackVerified Purchase

I got a single bag of this stuff for a 20g tank. It filled it up well enough. I think another half a bag would have been preferred, but it didn't justify buying another full bag, so I used one.

As noted by the product, this is not your "normal" gravel. It comes in a bag partially filled with water. It does not need to be rinsed. Just put it right in your tank.

I got this stuff for 3 reasons, which are:

1) I planned to get, which since then I have, some nerite snails, dwarf shrimp, and some friendly bottom swimmers, and I figured smaller grain would better for those types of fish.

2) Most tanks have the "normal" gravel, and quite frankly I wanted something a little different. And I couldn't be happier. I really like the look of this stuff. Some of the smaller, almost sand size, particles have a nice gloss so there's almost a little bit of a glitter to it. Not crazy or anything, but just enough to give it kind of a cool look.

&

3) I wanted to experiment with live plants. I was sick of the artificial plastic plant décor, and when I was searching for a good substrate I stumbled upon this stuff. And the live plants I've purchased so far seem to be doing pretty good. And they stayed put with relatively little effort.

All said and done I'm very happy with the purchase, and I'm so glad I took a shot. I will never buy "normal" gravel again.

The best substrate I used

ByAnneon November 30, 2014

Size: 20 PoundColor: blackVerified Purchase

I added it straight to my tank without rinsing it. I was worried that the substrate was going to be small and sand-like but its a good size and it doesn't harm my corys or pleco. My plants have been thriving and are very healthy. Its low maintenance and looks great. The gravel stays looking clean. A must buy for planted tanks!

Eco-Complete is awesome

Byrollntideron February 22, 2012

Size: 20 PoundColor: blackVerified Purchase

I like Eco complete for various reasons.

1) Dark almost black appearance. If you want that look this is the substrate for you. It wont fade like the painted gravel.

2) CEC- basically it absorbs nutrients and your plants take the nutrients from the rocks (in a nutshell)

3) no cleaning of the rocks- open the bag, pour it in your tank, no rinsing, no mess....plug and play

4) fish safe- I am a cory cat fish nut, and I hear people say it will cut their barbels... that is an urban legend. this is my 3rd tank I am using this on, all of my cories have long nice healthy barbels.

5) Easy to plant, grab my tongs/tweezers and push plant into place.

6) Cheap- cheaper than Aqua soil or fluval or whatever. 20 pounds of clown puke (colored gravel) is the same price.

7) I can push my plant tabs in the substrate with ease. I do the home made osmocote plus (which I bought from amazon)

8)Stable- it won't break down like aquasoil will, wont raise ph, ammonia etc....

With the money I save I can buy some plants or some fish.

Makes for a Dramatic Tank

ByAdobe Gardeneron October 17, 2015

Size: 20 PoundColor: blackVerified Purchase

I've used both Flourite and Eco-Complete in my planted tanks. I prefer Flourite mainly because I like the red-brown color and the texture. Eco-complete is darker and has rounder grains of various sizes, ranging from sand to pebbles. The Flourite grains also seem heavier and settle firmer; the Eco-Complete is easily disturbed. But I hate all the labor and massive amounts of water involved in cleaning Flourite. Thus, my latest tank has an Eco-complete substrate. Open the bag, pour it in (liquid and all), add water (carefully, to minimize agitating the substrate) and plants. While it's murky at first (although NOTHING like the black mud coming out of that Flourite), it clears by the next day or so. My Amazon plants and crypts established quickly (with the help of adding Excel) and are rooting well, although I had to use plant anchors to keep them in place at first. Despite what the bag says, you still have to cycle your tank (using Stabilize will lessen the cycle length). If I do another tank, what will I use? Although this is a good product and easy to use, I'm thinking I really prefer the Flourite despite it being such a pain to clean.

It works great and doesn't cloud up the water

Bychom choms dadon November 30, 2015

Size: 20 PoundColor: blackVerified Purchase

I have several planted tanks and have been using CaribSea for a while. It works great and doesn't cloud up the water. My discus and angels don't seem to mind it at all. The material is fine and seems to hold the plant roots down pretty well. It's a good item when compared to more expensive planted substrates.

Good stuff

ByEd B.on September 25, 2013

Size: 20 PoundColor: blackVerified Purchase

20 gallon glass tank. Heavily aquascaped. One bag barely cuts it. Two bags is overkill. I'm stuck in the middle. I bought one bag and the difference is amazing. Plants are deeper color, healthier and pearling now. I'll be back for more of this when I need the mid-sized black gravel. Oh, it comes in a surprisingly heavy bag. OPEN WITH CARE! The bag has a lot of liquid in it. This isn't dry, sterile groundcover. It has the bio starter that is desired but it will also cloud your water for a day or two before it settles. I would buy again.

Great substrate

ByJeffon July 22, 2014

Size: 20 PoundColor: blackVerified Purchase

I really like the look of the Eco Complete. I have used it with Fluorite black sand, and they go well together and gave the look I wanted.

Pros:
1. Plants seem to enjoy it.
2. Easy to plant into and holds in place very well.
3. Not jagged unlike other brands that could be harmful to cory's or loaches.
4. Speeds up cycling of tank, and if you are impatient like me, that is a very good thing.
5. Zero rinsing needed. Did not cause any cloudiness in my 90 gallon tank.

Cons
1. SMELLS TERRIBLE OUT OF BAG. I believe "burnt tire mixed with chocolate" is appropriate. Needless to say, it was a bizarre smell that I don't care to whiff again. That said, once in water you don't smell it at all.
