General Discussion : What is the right amount of light?

Further thoughts on this subject. The length of exposure is as important to coral as is the intensity. This fact has been well known in the hobby for years. Since we want to look at our tanks from sunup to way past sundown, it's useful to set the intensity at a moderate level yet have it shine from morning until we go to bed. This delivers the same useful "quantity" of light energy, spread out over a longer photoperiod.
Taking between 1/2 to 1 hour to ramp up (rather than 4 hours as in the schedule pictured above, is also more useful to the coral. 
There is another reason to run the channels at less than 50% intensity. LED's lose intensity about 5%/year before they either burn out or just glow. This means after 5 years they are only 75% as bright as when we bought them. Having the ability to increase the power can keep them shining bright enough on our tanks for, hopefully, 10 years or more. 
Just my 2 cents. 
Aloha,Mark

I'm currently looking for a large clean up crew for my tank and am wondering if anyone knows where I can find one locally, not interested in buying online.

The WMAS was formed to help us learn from each others experiences in reefkeeping. This is why I began to compile a list of Reefkeeping Tips and how to do a reef aquarium without spending your life savings.  It's not just my 25 years of experience but the experience of hundreds of other hobbyists that have come and gone on this forum. It is a topical guide; many discussions of problems and solutions and even how to avoid problems before they start by setting up the reef tank the best way possible, with live stuff from our tanks. **
Aloha,Mark  808-345-1049 (call/text to get immediate help or simply to discuss options)

P.S.When I started my first tank I was much younger. Now I'm a sometimes grouchy old man, but I hope I am still young at heart when it comes to this hobby.  I highly recommend perusing the Reefkeeping Tips thread linked below in my signature line.
** Twice in the last month or so I have driven from Murray to Ogden to share with new hobbyists; to share live stuff from my mature reef systems and information from my old brain. And I'm not the only one here that is willing to share.

General Discussion : Testing Reagents

Good advice.
Checking/verifying numbers is good practice.

An LFS and/or tank maintenance service burns through reagent fairly quickly with multiple tank water samples. They usually notice right away, by referring back to the testing history, when a bottle of faulty reagent has been received/used.

Along this same line, not too long ago I was checking salinity of the water in the bag holding a fish from Rusty's Reefs. It was way high, like 1.030.   

But it wasn't what I thought. The problem was with me. My refractometer was off. Turns out that Rusty had compared three separate salinty standard solutions from three separate manufacturers. They each agreed.

Since then I have compared refractometers and hydrometers that I come across, finding all of them to be reading wrong, mostly too high. Even when calibrated with pure water, they are wrong, as was mine!

But so what. It doesn't really matter much. Fish and coral can live just fine in salinity(specific gravity) anywhere between 1.018 and 1.030 and they tolerate modest variations that come quickly. Currents can bring water of varying specific gravity and heavy storms can dump so much fresh water that there can be a significant drop in salinity in a very short amount of time.

It's not a bad idea to always check the salinity of the water surrounding a newly acquired animal and adjust accordingly. I do not suggest drip acclimation as that causes more problems than it solves. I just take a few more minutes to acclimate an animal to higher salinity.

Aloha,
Mark

General Discussion : What is the right amount of light?

Maybe I wasn't clear. That schedule is one that I believe to be inappropriate. I do not use it. It was sent to me by a friend, new to the hobby that recently sunburned all his coral and the Coralline Algae on the tops of LR. Many of the coral received a fatal dose of bright light (mostly blues set at close to 100%) in just a few days. His coral started dieing a week after the overexposure and kept dieing for two weeks.

There is very serious trouble with this blue light, formerly referred to as Actinic blue, that hobbyists may not realize. It is the fact that our eyes do not recognize the intensity of this bright blue light. It is burning our coral but we can't see it. We only see the effect after the sunburn.

Copied below for your benefit, is what I said in the OP about the problem I see with that pictured schedule. I was wondering if anyone else sees the same problems that I see:
1. the intensity of the blues is set too high;
2. the effective photoperiod is set too short (with sunrise and sunset ramping set way too long);
3. the spectrum of light may actually be inadequate

Aloha,
Mark

P.S. It's very difficult to get an accurate PAR reading of LED lights, because they emit such a narrow band of the complete spectrum. On!y the newest, high price, top-of-the-line PAR meters can give an accurate reading.
Red, green and white, are not just for our eyes. The white LED's in these Hydra and Prime fixtures probably emit some red and green too. In shallow water, where many SPS coral live, coral are exposed to a fuller spectrum, including UV. These days we don't bring coral directly from the ocean to our tanks. Coral we see today has been grown under artificial lighting, typically less intense than in the wild.

Having been exposed to all the different types of lighting this hobby has used, and finding MH lighting to be a standard to which we often compare, I found my recent installation of a 150 W 14000 K MH and a Hydra 26 on either side of a tank to be quite revealing. To make the LED light match the MH, the violet, blues and white were set in the high 30% intensity with UV, red and green about half that.

I have to move, the tank can't come with me.  :(  Make me an offer, I'll take just about anything if you can pick it up soon.
150g "squat" tank with rear overflow.  The tank is 48" long, 30" deep, and 24" tall, lots of floor space.  :)  It's 1/2" starfire glass with beveled corners.  The back is painted black.  It has three holes in the bottom of the overflow, 1.75" diameter.  It was purchased in 2002.
The tank is dirty, it was used as a planted fresh water aquarium for the last two years and has algae on the inside and a bit of sand in the bottom still  I just emptied it yesterday.  It has one scratch on the inside left panel, about four inches long and not really noticeable when the glass is clean.
I also have two ATI SunPower 36" T5 light fixtures with dimmers.  Two cords per fixture, four bulbs in each, so two bulbs per power cord.  They are a bit dusty but otherwise in great shape.
The tank stand was made by Dion 7 or 8 years ago.  It's in pretty bad shape but you can have it if you want it.  The tank is very heavy, so bring lots of muscle.
I live in Murray off 54th south.  I am moving out on Saturday, so any offers that include picking up on Friday or Saturday will be considered first.  Make an offer, I'll consider anything.
