The Protein Skimmer is Necessary (I am looking at you, Nano Reef)

You also have a much larger than nano tank. And you ramp up and down your lighting intensity. I'm not sure what the point of these two posts is? Yes photo period can be longer than 7 hours, but is unnecessary for coral health, and was likely a contributing factor to OP algae issues is HIS NANO tank. Obviously all tanks are different, but when I see algae problems and a 12 hr. Photoperiod, I always decrease it.
I felt this was an important observation since he didn't even mention it in his rant.


My point was that your objection to a 12 hr light period does not apply to all tanks but the way you worded it suggests that a light period longer than 10hrs or your own 7hrs is bad for all tanks.

If you had said, because of your high nutrients, a long light period would not be a good idea since the algae would outcompete everything else, would have limited your observation to his tank.

I. I wasn't telling anyone they shouldn't have more light hours than me. We weren't talking about anybody's tanks but his until I used my tank as an example, it should be pretty obvious I was making suggestions for the op situation.
To use your own logic against you, your post makes it seem like everybody should have a 16hr photoperiod no? Maybe you needed to spell it out that it wouldn't work for everybody? If your point was to have a rebuttal to my post then you could've done that, your post of my photoperiod is 16hr really doesn't help the discussion any imo.
 
Not really because I never said a 16hr light period is bad or good, nor did I recommend it in that post for anyone else nor tell anyone not to run it.

I just stated a fact that I run my lights that long in response to your post about 12hr light periods being bad as fact.

As to if I would run my lights that long if I had algae problem, in fact I did. My light schedule hasn't really changed since I started my 40g AIO. My nutrient export methods have. I had algae problems in that tank as well as the 40b I'm running right now.

But I changed my nutrient export in the 40b and it hasn't had any algae problems since.

Yes absolutely! That's my agenda, shove my way down everyone's throat!

/sarcasm

If I misunderstood your post, could others as well?

Could someone reading thread, read your post and decide to lower their light period because they read that you said 12hrs was too long and you only run 7hrs?

If someone else asks why did they did that, they can quote your post and prove them wrong! Coral Reefer said a 12hr light period is too long!

All I'm saying a little bit more info to clarify what you are saying will go a long way in making sure the info you are giving cannot be misinterpreted any other way other than what you intended.

I don't have anything to say about poop, butt ;)

The length of the lighting period can certainly be a factor in excess algae growth, as can the wavelengths emitted (especially warmer colors like 'red'), the intensity and the DLI (Daily Light Integral). The equatorial daylight length is 12 hrs. and some might think this is optimal. However, during the first and last hour of the daylight period (approximately) the light doesn't penetrate the water surface due the shallow angle of incidence (violet and blue wavelengths start to penetrate after ~15 degrees is achieved). So if one follows a natural equatorial cycle, then 10 hr. lighting cycle with around 2 to 2-1/2 hrs. of gradual ramp up and ramp down would be a decent approximation.

Now having said that, corals are very adaptable organisms and can do very well with a somewhat shorter or even a bit longer daylight periods. I noted this on my last trip to Palau where many of the best concentrations of LPS (Brains, Lobos, etc.) were in lagoons surrounded by the iconic limestone hillocks of the area. Many of these corals didn't receive direct light until 10 or 11 am and they were back in indirect light/shadow again around 2-3 pm. On the flip side, vast fields of acropora in open reef areas were subjected to the full 12 hour daylight period with peak lighting of around 6-7 hours.

Getting back to algae, herbivores are of special importance, both on the reef and in our tanks. Pico and nano tanks have a challenge in this regard due to a much smaller choice of organisms that are suitable for the small sizes. However, various hermit crabs and snails can help contain growth, but not if it becomes excessive due to other factors. Of equal importance is coverage of bare live rock areas with corals and the like. As well as being direct competitors with algae for nutrients, they deny space to would be algae settlers. Another often neglected piece is the productivity of the benthic micro organisms that perform various reduction processes. I use weekly gravel vacuuming as a method to remove some of the bacteria, which then causes the rest to reproduce, which consumes and sequesters nitrates and phosphates (as well as other nutrients). The process also serves the function of removing decaying material that can contribute to increasing in tank nutrients.

Using various 'natural' processes and regular 10% water changes means that GAC, GFO, skimmers, polypads, etc. are not necessary in my old nano and these methods are effective in keeping PO4 consistently undetectable and NO3 at 1 ppm or less (Salifert kits).

Happy reefing! :)

Thanks for the in depth post. Maybe this will satisfy Vincent's requirements for elaboration.

That is my response because this was your post

12 hours is WAY too long imo. Heck, even 10 is pretty long. I'm at 7 total hours lights on and that includes ramp up and down. I believe that is the major factor in your algae issues.

Which I don't agree with.

But you were not talking about in general were you? You were talking about OP's tank specifically. Which was my point.

If you can't see how your statement can be taken out of context and misinterpreted by someone else then I'll leave it at that.

Given light and enough nutrients, algae will grow. They grow faster than (I would imagine) soft coral and definitely faster than hard.

While long light periods will certainly give algae more energy for growth, short light periods will not really get rid of any algae you have. This only treats the symptom and not the cause.

Find out why you have excess nutrients. Figure out why your nutrient export is not up to par.

If you have corals, fiddling around with light periods and changing water parameters rapidly will stress them out more than the algae really affects them. Unless of course if you have algae covering the corals. If you left it that long, drastic measures maybe required.

I don't understand why you purposefully keep misinterpreting it? Just doesn't make sense to me. Someone else possibly could take it out of context, so you do so on purpose? Do you fall down a flight of stairs. Cause the railing isn't in good condition because someone else possible could?
 
My light period is 16hrs long.

And this couldn't be misinterpreted as instruction for other people to leave their lights on 16 hours? I don't think that is good advice for most people. Especially when they are already having algae issues. You can't have your cake and eat it too.
Either bust my balls and make your posts not have the same issue as mine, or keep your overly picky problems with my posts to yourself please.
 
Simple distinction. I wasn't giving advice. If anyone feels like my tank is doing well and want to emulate my settings, be my guest.

Firstly, I did not purposefully misinterpret your post. Meaning I did not single out your post to attack. I did not reply to provide a teaching point or to point out what I thought was wrong with your post. My post was a simple response to yours.

Your second post made me think that maybe you meant it specifically for nano tanks with alage problems.

Then you posted this

Yes photo period can be longer than 7 hours, but is unnecessary for coral health, and was likely a contributing factor to OP algae issues is HIS NANO tank.

Put in bold what I'm responding to.

And this little gem.

My poop doesn't stink. Now we have contributed equally useful posts to this discussion.

All my subsequent posts were to show you WHY I posted what I posted. Not because I wanted to show what could happen but to explain why it DID happen.
 
To add some science to the conversation, Dana Riddle's article references tests done on a Torch coral using prolonged and continuous lighting:

http://www.advancedaquarist.com/2009/5/aafeature

The takeaway here is that 17 hours of lighting caused abnormalities in cell division. 16 hrs. would then appear to be an upper threshold before such issues come into play.

Interesting read. However the photoperiods are in relation to how many Mol photons received. And that is relative to PAR. Most home aquaria cannot achieve the PAR levels recorded. Meaning the number of Mol photons received in the same light period will be lower, much lower.
 
Can one of you be the bigger person and just let it go? You're both well respected in our community and it's like watching parents fight.
