Light and salinity

[jeharrisonjr]

I was wondering how many hours everyone keeps there light on for. I've been turning it on between 7-8am and shutting it off between 10-11pm. Also what is everyone running for a salt level, mine is around 1.025. Thanks

I run my lights 8 hrs a day from 9am to 5pm. I have mine on a timer. I used to run mine longer but it seemed the corals didn't benefit but the algae sure did. :sad:

Your salinity looks good.

Ok I'm planning on picking up a timer today and I've had a lot of algae I was going to try 12 hours

How are your water parameters? Ammonia, nitrite, nitrate, and phosphate? These can contribute to algae problems, especially when combined with a long photoperiod.

Ammonia=.25, nitrate=0,kh=14,cacium=440,phospate=.25,ph=8.5

Ammonia is .25?! I hope that was a typo or you've got some issues...

You may want to scale back a couple hours.

[jeharrisonjr]

So 8 hours?

Yep, 8 hours would be good.

 

[jeharrisonjr]

Should I keep my saltinity at 1.025?

That's a good level for sps. Don't really know if salinity has anything to do with algae growth.

Might want to take it down even under 8 hours a day for a while depending on what kind of lighting your using and whats in the tank till you get the algae under control. I had a bad algae and dino outbreak a while back and went from almost 10 hours a day down to 2 hours a day just to keep my coral alive but to kill the bad stuff, for about a 3day peroid and slowly brought it back up over about two weeks. Now my actinic are on 6 hrs a day and halides are on 4 of that 6 and things are going good. Also make sure to do frequent water changes using RO/Di water. Tap water can do funny things to a tank i learned that the hard way.

It looks like just the regular brown algae that builds up on your glass if the lights are on to long. Dino usually is a long stringy brown gooey looking stuff that takes over your live rock and corals.

+1 on what Bjledbetter said about lighting and RO/DI water.

There is some stringy purple stuff off the sand and rocks. Its not much but I'm going to try and keep it low.

If I have ammonia ur tank is still cycling. I hope u don't have any corals in there. How long the tank been up? Also ur kh is way to high I run mine around 9. NSW is like 7dkh. Def don't run your lights so long 12 hours max even less since your having algae problems.
