Gravel w/laterite-good enough?
I have 55 gallon with fish and plants. I converted my fish only tank to plants and fish about 2 months ago. I tore down the whole tank and put down a layer of laterite then small gravel on top. Now after doing more reserach, I see most people are going with flourite or sand. I hate to tear down my tank again! Will I do OK with the substrate that I have? I'd like to have a moderate light setup with CO2.
