planted tank equipment advice

I've had this tank for a year and a half and I've always had plants, but i want to go more serious with my plants.

Im planning to replace some fish and the hornwort and get some new plants and fish.
I need recommendations for best DIY CO2 injector and planted tank substrate. For the CO2, how often to have it on?

If you really want to do DIY, I've used this on my 75G before I got a regulator, etc. and I'm currently using it on my 29G:

Do the citric acid and baking soda method; it's much better than sugar and yeast. I 1.5x the amounts of everything and it lasts me 1 week. There are YouTube videos on how to set it up, the directions seem a bit complicated, but it's not bad at all.

@beckyhiker is right about choosing citric acid over yeast, but if you're really serious, you should go pressurized CO2. It's cheaper in the long run, more stable, easier to control and you set it and forget it until the CO2 tank runs out in 6 months. Then you fill the tank up for $20.

CO2 should come on an hour before lights come on and go off an hour before lights go off. Plants don't use CO2 at night, they use O2 then.

Substrate: there are a million preferences in this regard. Just put "substrate" into the TPT search and you can begin collecting opinions. I've used Flourite and Onyx Sand and my plants are thriving, but there is so much else involved. Plants will thrive with all nutrients being in the water column. Nutrients (from soil type or root tabs) in the substrate will only marginally improve certain plants.

Do you feel comfortable with the light and ferts aspect of high-tech setups?
