New to Plants and Need a Few Questions Answered
Figured this site would be the best resource for getting answers in regards to aquarium plants and lights.
The Tank: I have a 38 gallon tank measuring 36" x 12" x 20" (LxWxH), with a small rock pile and about 3/4" of fine silica sand . The tank has a small colony of Juliodochromis Marlieri consisting of three adults, fry and a few tiny pond snails. Current lighting consists of a 24" t8 18 watt fixture 12 hrs/day (no other info on light). The current plants in the tank are anubias, java fern, and 2 vallisneria (corkscrew I think). The Anubias is doing good and the java fern is slowly bouncing back from being moved but the vals arent looking so great. The vals were planted about 3 weeks to a month ago and each has one leaf that is melting and one has a couple leaves that are getting a couple spots on them.
Will sand work as a substrate for these vals?
I was considering getting a 36" dual T5 light (78 watts). Would this be a good light or is there a better option for lighting?
Should I be fertilizing? if so should it be root tabs?
My goal is to have the vals actually growing instead of appear to be dying. I do want to avoid getting into C02. I'm new to this and any suggestions as far as light upgrade etc is appreciated.
