direct sunlight verses LED/lamps

I'd like to know the difference between the two and how they affect plant life differently. also does direct sunlight make algae grow faster than artificial lighting? i always remembered my friends tanks that he left out in the open, they were all super alage'd up, not sure if he just didnt clean it often or if it was sunlight? like the warmth er something? post your experiences plz kbye.

This is like asking for the difference between a 2012 Dodge Charger and a racing car. In other words, there are LED lights that can light up a tank so bright the fish go blind, and there are LED lights that are barely more than moonlights.

If you use open shade, no direct sunlight, and match the PAR that you get with that, with a LED light, using cool white and or neutral white colors, I doubt that there would be much difference in how the plants do.

That would help if the algae you had was free floating in the water, however the majority of the algae would grow on surfaces which I do not believe would be affected by a sterilizer.

I just know my old citizen solar powered watch said you could charge it by leaving it under regular indoor lights for 2-4 hours, or 7 minutes in full bright sun. Pretty huge difference.

I would be more concerned with heat than algae... who cares about algae when all your plants and fish are dead.

I second that opinion.
