I'm determined to get these plants to stay alive. I want to have a decently heavy planted tank but I'm having issues. What substrates and ferts work well on a budget? I was looking into getting seachem flourite clay substrate with flourish tabs as I only have typical run of the mill gravel in my tank at the moment, not to mention its not very deep. I only have temples right now and they have barely grown since I got them since I bought them a month ago. I have a 20 gal with 4 otos, 2 ADFs and a betta hence why I'm trying to better plant this aquarium. plant suggestions are also very welcome!!
