All the debating aside, I do have a couple more thoughts which I've been pondering about for a while. Let me start by saying again my Ecoxotic panoramas LEDs have been wonderful, not a single complaint regarding any coral so far (1 year point). But maybe someone can weigh in on two questions / thoughts which have been bothering me.
1. My first question is especially for SPS
and corals close to the surface of the water on the reef or in the tank. The sun and MH
both direct ALOT of heat energy along with light into the tissue of the corals. I understand it comes as a package, but with LEDs this heat energy for the most part isn't there. Are there any consequences of that missing heat energy?
2. With LEDs getting so extreme with higher and higher wattage, ( EXAMPLE: wave-point coming out with a new high output 3.5 watt per led
, 336 watt 48" fixture), it's getting to the point where is it really worth it. Other high power LED
fixtures need to be hung way above the tank or spotlighting and coverage can be an issue. The initial costs are extremely expensive, the heat transfer / output is getting really hot (yes they do get very hot too, especially at 3 watts or more), and they're beginning to catch up to MH
I know of others who have purchased high output LEDs, but ended up needing a chiller anyway. With my lower watt ecoxtics, I don't need a chiller at all, but if I needed a chiller anyway, I still would have to choose MH
. I just don't have the money for a nicne chiller.
Of course I still feel light is only a third of the deal. In my opinion, water quality and current (water movement) are 2/3's of the equation. I've had far better success growing sps
and 1 watt LEDs, than others with halides and no experience.
