What should I do with the lighting in my sump? Leave it on all the time, or put it on 12/12. Since I've had the sump(bout a month)the light has been on 24/7. I've experimented recently by turning it off during the day. The tips of all the plant alge got white. Is there something I should be putting in the water or doing special, cause the plant alge don't seem to grow. I got a T5 24" on a 12 gal
sump, it's mounted pretty high due to the PVC
intakes and returns. Is this my problem, not enough or the wrong light?
