So I've had both Eco-Complete and ActivFlora in a multitude of tanks. Lately I've been leaning more towards Activ-Flora and really want to put both to the test. Here we go:
Both substrates I took straight out of the bag (huray for left overs). Pulled a run of glosso from one of my tanks. Cut off 4 identical pieces in line off the same "run" and placed 2 in each jar and filled with water. No ferts or dosing of any kind. Both under the same 3W Deep Blue 6,7k Solar Max. I'll keep track every few days or so.
The Eco-Complete grew the first new plant followed by ActivFlora growing the next two and finally Eco-Complete with the last one. Both have 4 plants in each glass so plant wise it's a tie. Just in the past day or two I have noticed the Eco-Complete plants starting to show signs of nutrient deficiency. I haven't added any nutrients to the containers so next week should be interesting. I did do 2 water changes thus far by simply running both containers under the faucet on a slow trickle. I wasn't planning of doing water changes but the Eco-Complete developed a slime coat almost and felt it was needed. The ActivFlora did have a little bit of settlement when I rinsed so both benefited I feel. I have noticed the Eco-Complete's substrate has really separated with the fine grain moving towards the bottom.
Haha, Justin we are in the great fortune of having it available for $25 in RI. If you pull the trigger on the 20 high I don't mind picking up 2 bags for you and can drop them off when I'm in the area. I got to North Kingstown and Fatima Hospital almost weekly. Plus I might be able to get my discount and get it a little cheaper yet.
