Good Day everybody !

I have really good news. I found the problem why Kick-Ich medication didn't work in my tank. I had to remove chemi-pure from the filtr and after that add this madication. So I did and I've got result next morning: my Flame Angale feel much better, he doesn't have any white spots at all!

I still have to learn a lot... I wonder for how long I have to keep light on in my tahk and when is the best time: morining, day, evening... Any advices ?
And why ? Please?

Thank you!
And have Great Day!

If you have a fish-only aquarium, you have a lot of flexibility in the lighting department. I would recommend a minimum of 10 hours/day and a maximum of 14 hours/day. Suit yourself.

If your system is isolated, like in a basement, you can choose any time at all for "daytime" and have it suit your available viewing time. This is a bit trickier if the tank is in a room that is lived in because of ambient light. Some folks start their lights as early as 6 a.m. or as late as 11 a.m. I wouldn't recommend starting any later than 11 a.m. unless your tank is in a room where you can control the ambient light.

Most people want to emulate natural conditions and that means a "day" that is approximately 12 hours long. The closer you get to the equator, the more even the length of night and day. Modifying that one or two hours in either direction is OK. If you ever decide to keep any photosynthetic animals (zooxanthellate corals, clams, anemones, etc.), you will need to provide a minimum of 10 hours of darkness daily for their good health. I think it's a good idea to provide fish with a minimum of 10 hours/day of darkness, too.
