Thank you for your comments and suggestions. I really appreciate it. Before I set up my tank, I have been researching for about six months, and based on the information that I gathered I thought 2x28W T5 (and not T5HO) would be right amount of light for the tank. May be I am wrong. Fortunately, I bought the Solarmax fixture that has independent switches for the two lights, so I can easily turn off one of the 28 watt lights. I will try that for a few days and see what happens. My immediate concern is that the two Swords in the back are getting yellow. Should I try Seachem root tabs?
Also, is this a good time to add a few otto cats to control algae?
As for the photos, one of my other hobbies is photography. Although these photos are nothing special, I have excellent equipments, which explains the quality of the pictures.
Thanks again for taking time to help.
