How much Amazonia did you add? It should be lowering pH, but i think it's competing with your other soils. ADA is going to release humic and fluvic acids to lower pH and absorb kH and other things in the water as it has a high CEC. Eco-complete has a very high CEC and may be absorbing the things the ADA is releasing and not allowing it the drop the pH. I've seen Eco complete raise or change parameters and I know some people say it's inert and doesn't but I've seen too many people on here to say it has messed with their param's as well.
I think you have two competing substrates and I'm not sure how it's going to work out in the long run. It's hard though that you layered your substrates, in a 150 gal tank no less, so you probably spent a tonne of money on substrate that you can never really remove in an easy fashion without either mixing it all up or scrapping it all.
What are you using to test your pH with?
Lastly, do the substrate in a cup test. I was getting massive algae in a few of my tanks after them running perfect with nothing changing for so long. Checked nitrates, 40ppm. changed water, back to 40ppm, changed more water, more, more, still 40ppm. Took out a cup full of aquasoil, in a cup, fresh water, 24 hours later, 40ppm nitrates. Bought a new nitrate test, 40ppm. My soil had absorbed all the nitrates from the water, then had enough and started releasing it.
