My eco is doing okay, but thanks for the comment on stem plants. I do have a bear of a time getting things to stay in the darn substrate. ><

Eco-Complete as a topping in Walstad Tank


I was thinking about using Eco-Complete as the top 1" layer in a new 55 gal Walstad planted tank and was wondering if anyone else had tried this and how well it worked. I'm also going to putting in a bristle nose pleco after it's cycled and roots have established. Will he uproot the plants with this substrate?

  1. Please suggest howmuch do I need for my 55 Gal (48x13x21).
  2. Do I need any Fertilizer underneeth this Substrate?
  3. DO I need to cover this Substrate with any gravel? Do any one know how soft it is? and how it is working out for them when doing gravel cleanups?
I just stumbled upon the sticky at the beginning here, and there is a calculator which helps with how much substrate you need.

Hi! I use this substrate, one bag for a 20 gallon high tank and I mean that I don't have any problem. Here I show you a video about this.

I found that eco complete is high in iron. I measure level of iron in substrate and is about 0.8ppm. More I fertilize water the iron level of substrate increase. Is that because substrate absorb it? When I increase water dosage to 0.07ppm Fe daily after some time Fe in my substrate is over 2ppm. Should I still dose Fe to the water or substrate release Fe into the water?
