Moss showing signs of browning, need advice
I have a two week old tank and I am experiencing some issues with the moss I have tied off to the stump in the tank browning heavily. The tank is fairly planted, I would say medium. It is soil based Miracle Grow Organic with a sand cap, no heater, filtered, no CO2. The tank receives 10 hours of light from a 13 W PCF 7100k light just above the water level. This is the light that came with the tank so it is not something I bought after market. I know the 7100k is not the best, I ordered replacement bulbs but I was not able to find them local so I have to wait for them to come from overseas. Lord only knows that may take two months. The tank sites on a west exposure and receives diffused light throughout the day as well.
For the most part all of the other plants in the tank seem to be doing okay. The aponogenton got a little ragged but I think that was it just acclimating. All the others, crypt wendtii, bacopa, dwarf baby tears and pigmy chain sword are doing okay. I have an anubias that is starting to get some funky brown on the leaves.. Since the stupid ghost shrimp I initially seeded the tank with all but died except for two there is nothing in there but those two and a lonely small olive nerite snail. I check the water params every day and everything is fine across the board. I am not dosing at the moment but I did order the medium tech + package from Pfertz (plug for forum sponsor).
Being that it is not planted and attached to the stump is it something I am lacking in the water? Since there is no fauna am I not providing enough nutrients and such for the plants to make it?? It is a lot of plants for a small tank and without anything in there making a mess I am not sure if that is causing it. If anyone has suggestions or ideas what might be going on with the moss I would appreciate the advice.
