Planted Substrate Question
I've been slowly assembling all the parts for a high tech planted 29 gallon tank and I'm days away from being able to start picking out the hardscape but first I need some input around substrate. I've done a number of different planted tanks in the past and they were all low tech. My thoughts are to use ADA Amazonia II, to build up the rear of the tank I'll be using lava rocks in mesh bags and using the Amazonia over it. At first I was considering the power sand as the base layer and the ADA additives over that before the Amazonia II but it seems most people are either 100% one way or the other. With the footprint being so small the power sand doesnt seem to be a big deal and the additives I'm still not sure about.
The question I have about the Powersand is the big selling point is water flow through that layer of the substrate. I could use some leftover ecocomplete I can use in place of the powersand that I would think allows for the same time of water flow. I know I'm probably overthinking this but I'd really like to get this right the first time.
Now the additives, is there any sense in them, some or all? The iron seemed to be the one that I thought about the most as I'd really like to add some red plants and it seems like its a great way to make sure the substrate can support their needs in the long term.
Appreciate any input that might help me get over this last hurdle.
