| | Need some help with my plants.. leaves turning brown? im new
I have a 55G community aquarium. I use to use sand as a substrate.. this stuff I bought from walmart like you would use in a sandbox. The plants I have are:
Some kind of grass-like plant
and some other unidentified plant. Small round leaves, very thick stem. Has vines/roots coming out of the stems.
Anyways, the Anacharis would grow nicely for a couple of days, then would stop and break apart. The grass would spread quickly, but wouldn't grow very tall and the blades would be limp. The unidenfied plant would grow for a day then fall apart just as quickly.. Often times I found myself having to replant the unidenfied plant, asi t would rot at the base of the stem where I had planted it.
I had assumed that the plants were having trouble because they weren't getting enough nutrients, so I replaced the substrate. I replaced the substrate with 40lbs flourite and 40lb caribsea eco-complete gravel. Now the anacharis is doing the same thing it did before, the grass isn't growing at all and the blade's edges are turning brown. The unidenfied plant doesn't seem to be rotting, but the leaves are also turning brown.
Why is this happening? I haven't had a plant turn brown on me, even when using the sand.. it was always soemthing else. So what's causing the leaves to turn brown?
For lighting I have two 40W NO bulbs and two 15w NO bulbs. No CO2, but occasionally I set up a custom CO2 system with yeast and sugar.. though my plants usually act different then they are now when they're wanting CO2.
Any help would be appreciated.
Also, I remember reading a site a while back that listed symptoms like these and said what the problem was. Would anyone know of which site I'm refering to?
