| || | Introduction and question
This is my first time on this forum and I am very happy to be here since a I am new to the hobby and I believe this is a site with plenty of knowledgeable and experience aquarists from whom i can learn a lot. As I introduce myself I would like to take a moment to thanks the Tropical Fish Keeping administrators for allowing me to be part of the community.
Well, I set up my first tank back in September 2012 and I started with 3 harlequin rasboras and 3 cardinal tetras. One of my cardinals die a few weeks after i brought him home and the other two are still in my tank. Also, one of my rasboras jumped out and die. Later on I brought home 1 more rasbora and another cardinal tetra as well as 5 chili rasboras. I also have two small snails. My tank size is 10 gallons. I have a multicolor gravel and some artificial and natural plants. I use an aqueon power filter and a 50 watt heater. In addition I have a hood with a fluorescent light. The tank, the lights and the filter came with the kit I bought initially.
I use API leaf zone weekly and Tetra flora pride monthly to fertilize the plants.
My water parameters as of yesterday are:
PH: bet 6.8 - 7.0
Nitrate: Bet 20 - 40
I have a question for you regarding my plants because I have noticed that some of my plants have dark spots on them and I am not sure what the cause for this would be. I believe there might be something going on with my water or that this is just some type of algae. I would greatly appreciate any advise you can give me about this issue and how to remediate it. Below are some pictures I took from one of the leaves.
