• light for the samp

  • Lee425

Hello, please advise what kind of light is best to use in a sump. What spectrum should it be for plants to grow well (like caulerpa and other filtering plants)? Also, please suggest some literature; I came across it on the forum but can't find it now. Someone recommended an author from Mariupol. P.S. If anyone from Donetsk has some plants in the sump, I would gladly accept them in exchange for some treats :-)

You can start from the preferences of chlorophyll A: I used red and royal blue diodes in a ratio of 2:1. I tried to stay within the ranges of 445-450nm and 660-670nm. It seems like they are growing =)
