Hello - new to the site! I'm moving soon and thinking about upgrading my 20g high planted tank in the process. Although I've had tanks my whole life, I just started getting into the planted tank scene. I've been doing research and I'm thinking about going with soil under gravel for substrate and a DIY CO2 generator (good idea?). The thing I'm having the most issues deciding on is lighting as I think I want to be around the medium light range (again I'm new to this, good idea?) because I like more colorful plants and love the way planet carpets look on the aquarium floor. I read a few other posts and it looks like the Finnex Planted+ 24/7 is a good option. My problem is the whole WPG thing is a little confusing so I'm wondering if anyone has advice on the best light for what I'm planning here. Any thoughts would go along way here! thank you.
