switching to sand, nutrient Q
as we speak, i'm switching to play sand in my established tank to aid the growth of carpeting plants like hair grass and glosso. i know i need nutrient rich substrate for those plants, but adding a layer of laterite or eco-complete seems like a chore and is out of my budget at the moment*. would it be sufficient to shove some root tabs into the sand before i plant? if so, how long do root tabs usually last?
* (i know root tabs cost money, too, as will my plant order. but i want to get the substrate complete now so that i can get parameters back in check. by then i can afford the plants and extra items to complete my co2 rig)
