Started this year with a 29 gal. Been making all the mistakes and learning from them. I have good lighting, CO2, nutrients, etc. Bad gravel substrate that i reused from a previous tank, stones from the garden, to much algae, not sure on dialing in the balance of things but still working on it and learning. I've been gathering everything for a new tank, 17 gal rimless, good plant substrate, glass Lily pipes, etc. Want to do it right this time! Haven't put it together yet, still have to write acquire hardscape, a stand, and a plan for the plants, but nearly ready to go with it!
