That's very nice of you to say mate, i enjoy following your reef and i'm actually keen to one day embrace LED technology once those of you who are braver than i work out the bugs and how to get the bloody things working as well as my radiums lol.
That picture comparison speaks volumes, the prism upgrade is definitely going to see positive results and will be an option on other units soon hopefully. I know exactly what you mean about the harshness of the LED's when at full noon lighting levels, appear much brighter to our eyes i think than halides and definitely T5 lit tanks.
That's interesting about the polyps under blue LED's because i noticed the acros extend about half way to their darkness extension under blue only LED's but under actinic fluoros they stay pretty much closed. A big bonus when you consider how many fluoro polyped acros we keep - i'm definitely having RB LED actinic viewing bars on the 7 footer. :thumbsup: Even flubber looks tolerable under RB's and that's saying something...........
I ordered a couple each of Salifert alk and calcium kits so i can do more regular monitoring and a Potassium kit just cause you did - i hope you realise that if i test and have low levels i'll have to spend yet more bloody money on a Potassium supplement........... your Potassium post is sending financial ripples around the reefing globe :wave: Also ordered another heater as i realised i didn't have a single spare in case of failure - i have been known to remove heaters from the water when running and 'tink' that's usually the end of that lol.
I tend to simulate a tidal pool cut off from the ocean permanently in regards to my water change simulation protocols.........:reading:
