I'm preparing to set up a new 20 gallon tank. I have a 20 lbs bag of Carib Sea eco-complete for my plants. I’d like to put a layer of sand on it. People mention using pool sand. I’ve found quickcrete all purpose sand at Home Depot that is labeled pool sand. I’m not sure if they would suffice? I’ve attached a photo of the two sand choices that I’ve narrowed it down to for my new tank. I also plan on transferring my current 10 plants from my existing 20 gallon tank that only has aquarium gravel. I would like to add more advanced plants now that I have my Fluval 3.0. Thank you for any assistance that you can provide.
