I working up the mental effort to begin the moving of my larger tanks from my parents house to my apartment. I've been neglecting them for around 3 weeks and the largest one will probably be a while longer. Anyway since my 20 gallon has been having issues lately with the plants I am redoing the substrate.
My goal with this tank is to have a soil substrate and it be able to run filterless like my other one. It will be continuing to get pressurized CO2, but not right away since I am doing a juggling of systems. This tank will likely get some EI fertilizers. What exactly is not known yet, though I am expecting nitrates to be needed eventually on all my tanks. There are a lot of unknowns with this tank, such as how many fish are currently in it lol. I do know it has mostly endlers, lima, and ameca. So a true livebearers tank.
I could use suggestions on my capping substrate over top the soil. Currently the tank has flourite as the substrate, which is what I could use. Or I could use sand similar to the last tank I did. Issue with sand is its more work to do lol.
Here is a picture of it before I pruned and did a waterchange the other day. I forgot to take a picture after I was done
