I have a high tech 180 and a high tech 75 been running with injected CO2 for 15 years and now fully LED these last 5 years. Been mixing my own ferts 15 years also. Happy to answer questions.
I converted from CFL to LED and found that with my chosen lights WPG was cut in half for the same amount of PAR. Every LED unit will be different though I think.
There is a wide variety of things that you can use. I've used John Innes number 3 recipe garden soil capped with 2-3mm sand for most of my tanks, I've also used fine grain moler clay. These are some of the more diy options, there are plenty of commercially available options out there.what substrate do plant people recommend? other than ada?
What plants are you growing in an AC tank with a high alkali substrate? Very nice tanks!View attachment 329463
