High tech and walstad questions.
So I have a 5 gallon walstad tank with a few shrimp at school with me, which is holding most of my plants. Back home I have a 20 gallon long that I want to convert into a Walstad and ditch the 5, but the problem is I would only be home for a week to oversee the transition. So I've got lighting all set, I've got about 2.5 watts per gallon of CFL 6700k lighting on the 20. However, that tank only has regular sand as a substrate. I want to switch out the substrate, but I feel like dieting a tank takes lots of time to set up and settle, which would leave the current stock of guppies, cories, otos, and a rubber-lipped pleco in a 5 gallon for far too long while the water settled. So I was wondering about simply switching out the Sand with Eco complete, but people have told me that it's good for plants, but soil is better.
Current plants I have are:
Dwarf hair grass
Green foxtail (I believe)
One amazon sword
And a thin leaf Val, not sure of the exact name.
So what kind of substrate should I use, or should I just keep the regular sand? I have people who would be able to make sure the tank is alright, but they're inexperienced with planted tanks, or aquariums in general.
Also an unrelated question, is it possible to dose CO2 and ferts until the plants have grown out and are nice and full, then lower the lighting and SLOWLY take away the ferts and CO2, transitioning into a walstad tank?
