I've decided on a few hardy species for my 10g dart frog tanks, among these species are pothos plants. I see them all the time at department stores but am afraid to put them in my dart frog tanks since they may have pesticides or something else on them. I can't find any websites that sell guaranteed clean pothos. Is there any way to buy store pothos and rid them of all pesticides? Also, about drainage, I've had problems keeping tanks well drained, probably since I may have overwatered. I've been thinking about a false bottom with a piece of airline tubing going down into the bottom so I could syphon water out if there ever was too much.What do you think about this? Thanks in advance.
