I'm new to this site but I am on the sister sight for bettas. The tank i have the problem with is a 15 gallon tank, using dirt and gravel. I switched to T5HO 48 watt light (one light is 6500 and the other is 5000k) a couple months ago. Plants range from swords (getting rid of them though), rotala, ludwigia, wisteria, hygro corymbosa, dwarf sag, frogbit, water lettuce, and some duckweed.
All my parameters for ammonia, nitrite, and nitrate are zero (Will test if anything changed). My water is a bit soft but high pH, not sure on the kH though.
I recently switched to the siesta method as I don't inject CO2, but do dose Excel. That is where the algae outbreak came from is my guess. The schedule is 7-12 on, then off till 4 turned off at 8. It is done by a timer btw.
Should I go back to a normal schedule or let the plants adjust to the siesta? I could also go back and do DIY co2 as well.
