QuoteReplyTopic: Recommended Lighting for tank Posted: May 09 2016 at 12:44pm
I have a RSM 130D with mostly softies (ie zoas and mushrooms with a few toadstools) and a few LPS like blastos and frog spawn. I "upgraded" the lighting to a fixture from rapidled.
Since then I've had nothing but issues. Half of the corals are extending like they aren't getting enough light and the other half are bleaching like they are getting to much light. I've already had a few zoas melt away and am seeing if anyone has recommendations on different LED's that they know work that I can switch to before I lose anything else.
Thanks for the quick reply. I have tried to move corals but some are attached to rocks that wouldn't be as easy to move. I don't know what my alk/ca is right now I'll have to take a water sample to a lfs. I can do that tonight.
My only deal was everything was at least fine before on the pc bulbs that it came with and I even had a temporary LED fixture that went over it before I got rid of it for the hood leds.
That's a good point though maybe I shouldn't blame it solely on my leds. I will test my parameters tonight and update my post.
The dimmable dials it came with aren't labeled so I generally have to eyeball it which I know isn't good but not much else I can do. I'm emailing the manufacturer to see about what controllers are compatible with the kit I got. I want to say the lighting is at about 75% I also ordered some test kits tonight so I should be able to test my water in a day or two.
Going from PC to full LED was probably a pretty big shock to the system. I would have started out light acclimating them at about 25% I know you can't be exact seems it's just a dial and then slowly moved them up in percentage over at least a few weeks period. If you started out at about 75% that would explain the bleaching as for the reaching sometimes certain corals will reach in different lighting. I even have a paly that is right at the top of my overflow gets tons of light and still reaches.

Because LED's put out narrower bands of light, one single band can actually be too intense and thereby cause havoc. That's why we start low at no more than 25% and increase by only 5-10% every 10 days or so. Lethal sunburn is real.
Regarding what Marcos brought up, when several conditions/parameters in the tank are teetering right on the edge, all it takes is one more thing to cause issues or even a full blown crash. Every reef aquarist needs to be keeping on top of the 4 most important parameters. I cannot say enough about Alk, Ca, Temp and SG. Have you read the Reefkeeping Tips? Please see the link below. These four parameters are so critical that it's the first thing I talk about after first instructing how to best set up a new tank.
Good to hear the test kits are on the way.
Aloha,
Mark
