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?
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?
