I need some help with my 5.5 gallon planted tank. I've been in the hobby for 11 years but just got into plants. I have Cryps, amazon swords, and anubias. I want to add more plants like ludwigia and maybe some more cryps. However I want to upgrade my substrate first. I'm running it low tech. I have a Finnex Stingray Clip on light, I put H20 root tabs in every 2 months, and I'm dosing half ML of Flourish once a week. My cryps are growing well, my amazon sword has shot out 6 new stems and I already trimmed some. Alge is barely growing. I feel like I have pretty good balance. Again though I want more plants but feel like root tabs won't be enough. I want to know if Fluval Stratum or dirt substrate is better. Even another substrate, but I can't find good answers on the internet because everyone has success and failures with both. I'm just trying to find what is right for me.
