Is this still too much light?


I have 2 tanks.

Tank 2: 20L -Tank 11" from top of tank to substrate. 30" aquaticlife 2 tube fixture however the tubes themselves are only 21 or 22 long. again the fixture is approx.3" from the clear lid and I have a screen on top.

Thank you

Too much light for what?

The 45 gallon tank probably has 25-30 micromols of PAR, or low light.

The 20L probably has about 50 micromols of PAR, medium light.
