• the browns are coming

  • Stephen5857

I installed a new 4*20W T-8 light for a 100L aquarium. The aquarium is six months old and there were no algae at all before, but now it's getting covered with a brown film at a crazy pace. The light has been on for a month. Should I not turn on the light for a couple of days or wait for the aquarium to re-establish itself under the new light? I'm afraid that an excess of algae might harm the aquarium. P.S. They say you can never have too much light.

There is a lot of white, red, and things that don't suit Riff, the invertebrates. So what did they put?

2 pcs of marine, 1 pc of power, 1 pc of sun-glow

As far as I know, white to blue (overall) is 1/3.

Here is your problem! Who recommended such lamps to you? Now, let's go in order. The T8 lamp, Hagen Sun-Glo, should not be used in a marine setup at all! You can use Power-Glo if you have a total of 8 pieces, but not when you have 4 pieces. This lamp stimulates the growth of aquarium plants and enhances the coloration of fish. These two lamps have given you a lot of red spectrum, with resulting consequences. Urgently remove Sun-Glo, and Power-Glo is at your discretion.

Thanks, I'll try. Should I just put a white one in place of San-Glo or remove it altogether? Right now, 1 Marina and 1 Power are on, and that's clearly not enough since even Ksyusha hasn't opened up.

And who knows what the optimal combination of T-8 for 100 liters and which lamps?

1 - Power, 3 - Marina.

A simple white one cannot be used; if a white one is to be used, the color temperature should be at least 10,000 K, preferably 15,000 K. For now, remove it. In your option, I would set it up like this. I note that among the T8 lamps, it is difficult to find Hagen 20W, as there is no necessary selection in the white spectrum. 1. ine-Glo 2. ine-Glo 3. Power-Glo 4. ine-Glo or try Aqua-Glo, 20W, with a temperature of 18,000 K, but be careful as it is very bright.

Okay, let's do it that way, thanks everyone for the info.
