View Full Version : Photon V2 Schedule

I was wondering if anyone who has been using these has found a good light schedule and is willing to share? I want a mixed reef tank but don't know how I should set the light schedule to accustom it. Thanks!

Also, this is my 185g tank and I'm getting ready for fish and corals. I see they recommend ramping up the light so you aren't bleaching the corals. Would do have to do this for every new coral I introduce?https://uploads.tapatalk-cdn.com/20171005/28249f760b7e98e4301b8f9c9e0ee242.jpghttps://uploads.tapatalk-cdn.com/20171005/0d7ce19ffb266ee4349ac19a9f40bb47.jpg

I recently made some small adjustments to shorten the ramp up and down. I wanted the lights out a bit sooner in the evening. But the numbers are almost the same.

My reef is a 125g and only 20" deep. It is more sps than anything, but there is a wide mix from zoas, to softies to lps and sps.

It looks like you'll have a lot of light on your system. Do you have access to a PAR meter?

I don't have a par meter. Too much light?

I am doing about 2/3 of what Ron is using (same fixture). I believe he would agree that the key is maintaining the correct ratio of blues to whites. I also have a 5% red for a several hours but I am not sure that is any benefit.

I don't know if that is too much light or not, but the good news is that you can easily tone it down. I am still trying to find the sweet spot.

I don't think you have too much light, just enough fixtures that if you run them at high enough settings, you could have too much light.

If you can't find a PAR meter (friends, club members, LFS, online) you can try this:

The 'canary in a coalmine' approach. Get a small frag of a red cap monti or any other inexpensive plating coral, and set it in your tank as high or higher than all the other corals. Start your acclimatization at a low number and raise it every week. You can raise it a bit faster early on, but get much more careful as you get up to higher power levels. When you raise the light intensity too high, the red cap will start to bleach before any other corals. At that point, dial the power back a bit (5% to 10%) and you should be good to go. :thumbsup:
