I am a little concerned, as my dwarf baby tears are looking a little brownish on some leaves. My CO2 levels are good according to the drop checker, my lights have been on about 15 hours a day and the temp is right on at 76 degrees. I have done 3 water changes since the tank was made on Wednesday, with the first two being 50%, and the last being 30%. I have read that some people get bubbles on the first day but no luck for me I guess.
I use the recommended amount of ADA brighty K, but am not sure if I have too much lighting at about 15hours or if I need to leave it on 24/7 initially? Any suggestions out there?
