Don't dose Excel just once a week. Dose it every day at 2 ml per 10 gallons of water. When you dose once a week that does no good, and may even encourage BBA to grow. If you can't afford Excel,...

If you don't dose Excel, and don't use CO2, you should either just top off the tank water, and maybe change 50+% every couple of months or longer. That is because most tap water has a lot of CO2 in...

Day to day, if you shut off the CO2 when the lights are off. Or 24/7 if you run the CO2 24 hours a day.

All bodies of water, including our aquariums, have CO2 dissolved in the water, from the atmosphere. That is about 3 ppm of CO2. That CO2 plus the carbonates in the water form a buffer for pH. The...
