It is very new. The tank has been set up since January, however I only started the plants/co2/fertilizer in June. So probably only a month or so with plants. Here are some photos:

For a new tank, this could be a max of two hours a day for a few months.

Secondly, make sure you are actually doing your water changes and siphoning up detritus regularly.

I have not considered this. I have my light on for 6 hours per day as I have read that is the minimum for plant health. I have been leaving it at 6 hours but decreasing intensity to try to find the balance. I did not realize I could potentially try stronger light for more robust growth for only two hours per day. I guess I would do this mainly until I was able to increase plant mass and then slowly increase it?

That brings up another thing I have thought about: how long should I wait between making changes? Should I change something then wait two weeks to see if there are effects? Is that too long/too quick? Thanks again for your help!
