Added some marineland 21" hidden led's. There in the 6500k range also. Boy did they brighten up the tank! Here's a before and after pic. The photo's are with my phone so they may not be the best.
I don't run them but for 6 to 7 hours.
6-7hours should be fine, algae normally grows from excess nutrients in a planted tank. So just make sure your ferts are balanced and you should be fine.
This is not true at all. This is very old school.
The entire EI Fertilization method developed by Tom Barr focuses on adding mass amounts of nutrients into the water column, so no nutrient can limit growth. Light/Co2 imbalances and a lack of nutrients are what cause algae blooms. I run my tanks 80+ ppm of nitrate and 10+ppm Phosphate. No algae.
That's not true. The nutrients are still in excess. You even said your self, a deficiency causes algae. Those excess nutrients do, but only because of a limiting nutrient. Excess nutrients without deficiencies do not cause algae.Before you jump to conclusions and say I'm wrong. It's actually is true the ei routine involves dosing to make sure no nutrient ever bottoms out. Meaning everything is in balance and there are no excess nutrients. If you bottom out in a certain trace element your plant doesn't use the rest become Excess nutrients and allow algae to feed..
You just said the same thing.That's not true. The nutrients are still in excess. You even said your self, a deficiency causes algae. Those excess nutrients do, but only because of a limiting nutrient. Excess nutrients without deficiencies do not cause algae.
