Eco Complete Planted Black Aquarium Substrate | Petco
I originally had one tank with only Eco-complete as a substrate and it did ok. I then read Diana Walstad's book and decided to try a soil layer in a different tank with small gravel as a cap which worked great (except that its hard to plant through the gravel). So, I changed out the Eco-complete only tank to Eco-complete over soil and the plants did start growing better. I've stayed with the Eco-complete because I like the way it looks and I find it quite easy to plant in it.
Mineralogical complete, contains Iron, Calcium, Magnesium, Potassium, Sulfur plus over 25 other elements to nourish your aquatic plants. Eco-Complete Planted Aquarium Substrate contains all the mineral nutrients needed for luxuriant aquatic plant growth without nuisance algae, Iron rich Eco-Complete eliminates the need for laterite, is nitrate and carbonate free, will not increase pH or carbonate hardness, no artificial dyes, paints, or chemical coatings.
Natural black substrate encourages the most vibrant coloration in fishes and reduces fish stress, spherical grains for optimum diffusion performance, supplies Calcium without raising pH, contains live Heterotrophic bacteria to rapidly convert fish waste into natural food for your aquatic plants.
Creates a natural biological balance which makes cycling a new aquarium faster and safer, its packed in Liquid Amazon buffered “Black Water” solution for immediate organic water conditioning, unsurpassed Macro Porosity for healthy roots and bacterial efficiency.
What does it mean Eco-Complete Planted Aquarium Substrate employs clever bi-modal grading, which naturally separates into 2 distinct layers: 1) Fine layer on the bottom for best root development, and 2) Coarse layer on top which conveys oxygen and nutrients to the roots.This plant substrate is named appropriately. It is the planted aquarium substrate. It's mineralogically and biologically complete. This substrate contains all the mineral nutrients needed for luxuriant aquatic plant growth without nuisance algae: Iron, Calcium, Magnesium, Potassium, Sulfur and over 25 other elements. It's spherical grains are designed for optimum diffusion performance. Iron rich Eco-Complete™ eliminates the need for laterite. It's carbonate free, meaning it will not raise pH or carbonate hardness. Furthermore, it supplies calcium without raising the pH. It's nitrate free and contains no artificial dyes, paints, lead, or chemical coatings.I am just speculating here and cannot speak directly to how well Eco-Complete would grow plants vs Seachem fluorite as Eco is on my list of substrates to test. When I grew plants in Fluorite, I found that the fluorite sucked when it came to growing rooting stem plants like ludwiga repens, ambulia, and rotala indica.For the record, NPTs don't have artificial CO2 injection. Therefore, plants in an NPT won't do well in a substrate that is pure Eco-Complete. Of course, one can put a little soil underneathe the Eco-Complete, and then its just fine for NPTs.My Answer: Eco-Complete looks like nice (attractive) gravel with some humic acids included. By itself, I don't believe it will support good plant growth (you'll need CO2 injection and regular plant fertilization). Therefore, I would put a 1 inch layer of soil on tank bottom. (I use Miracle Grow Organic Choice Potting Mix, which doesn't have added chemical fertilizers.) You can put the Eco-Complete (or some other gravel) on the top. Be careful to not make substrate too deep; it could go anaerobic and kill plant roots.At the time, I had just bought Diana's book and had two 10 Gal NPTs set up and was sold on the low-tech methodology. Instead of fighting the BBA any longer, I decided to take the 30 gal down and set it back up with a soil substrate. The Eco-complete was used for the substrate topper after I sifted all the sand out of it. I noticed the sand while cleaning the EC and since the soil I was using already had some sand in it, the EC sand got tossed. I suspect this sand is one of the keys for success with EC, providing much more surface area and a more soil-like interface with plant roots.
