I bought the pea gravel and tried to add it to the already water-filled tank. Even thought I had rinsed the gravel, it clouded up the tank something awful. So, I went back to square one, and restarted the tank, this time putting the gravel in first after rinsing it a few more times. It looks good now. And no more blue water.
Thanks for that list, fish_4_all. I compiled the info from that site into a "Yes" and "No" list. I presented it to the lady at the fish/aquatic plant place (not PetSmart, it's another place I found) and got a chuckle and funny looks, but they seemed to have true aquatic plants there.
I bought a Cardinal Plant, a Wentii, and another plant which name I cannot remember. I also bought some Java Moss
, but I had to take it out because it became scattered around the tank and started clogging the filter. I'd like to get something less likely to float up and more likely to cover the gravel instead.
Unfortunately, I bouht the plants before redoing the tank and they took a bit of beating while I put them aside to wait for the water to dechlorinate again. But they seem to be rebounding just fine, and I've now got my tank set up with the plants and two African Dwarf Frogs.
