why are you going to get rid of the rock and sand if you did that the tank will cyicle again
Well when u throw it out I will take it
The sand or the rock?
Bottom line: LEDs can put out the PAR and can grow corals great. But i do think there are alot of slimy forgien companies that are playing up this PUR, while discounting PAR, Because they are using cheap knock off LEDs and charging premium. Also, with good blue LEDs you can probably keep good color on corals for awhile without hitting them with enough PAR to reach photosaturation (thus allowing maxium nutrition via zooanthelle). Stick to quality LEDs, manufacturers, check your PAR, and ensure you acclimate to the LEDs. They can be very focused and you may get more of an average PAR reading while a coral is direcly in the "beam" of an LED and gets friedLight is light, Photons are photons, radiation is radiation.
I agree 100%. Orphek is discrediting PAR mainly because the LEDs they are using are their own, "specially formulated". Building up some Hype over nothing. So they need to find a way to sucker someone into buying their $900 60 led system. Though their system is mainly desined for deep waters. My corals have been happy at 250-300 PAR, when i ramped them up to 350, they werent too happy 3 days later.
Myself and Chromulux, (Andy) both run Orphak and up to my old Led's they are second to none!!. A little pricey but what isnt in this hobby, you get what you pay for!!
