Green water..HELP

Our tank has been green for about 2 weeks now. All water parameters are very good:

ammonia - 0
Nitrite - 0
Nitrate - 0
PH - 8.1

Salinity 1.024
Phosphates - undetectable
Silicates - undetectable
Temp: 77-78

These are some things we have recently done to try to fix our problem:

We have added an additional 40 pounds of liverock from liverocks.com to bring our total LR to 75 pounds. We have replaced the gravel in our canister filter with live rock rubble. We are running a carbon bag in the canister filter. We pulled off our recently added Aqua C Remora Pre-Skimmer incase that was the problem. We have done a 20% water change. (We dont use tap water, we mix our own with distilled and test it thoroughly prior to adding). The water we took our was very green but you can even tell we did anything, the tank still looks green. We were told to reduce our lights to 5 hours a day by the LFS. We did that for a week and no change. Now back to our normal 10 hours a day. The tank does not get any natural sunlight.

All livestock seem fine and we feed once daily. We feed brine one day and mysis the next, back and forth.

I know some of you have offered suggestions in another thread but I belive I've done them all and nothing is improving this issue.

We need more ideas, please!

TIA
DJ

If your waters green, then get a UV light. That will clean it up.

I have a 1500gal pond which started to turn green so I bought a UV light and in two days, it was looking clear as day.

I have the 30" Coralife Lunar Aqualights. I don't think we have the UV lights you've mentioned. Here are the specs on my light:

Double Linear Strip with 2-65 watt True Actinic and 2-65 watt 10,000K Compact Fluorescent Lamps Straight Pin Base with Cooling Fans.3-3/4 watt Blue-Moon-Glow LED Lamps 3 On/Off switches

If I don't already have what you are talking about, please tell me where do I get it and how do I add it to my setup? I've seen UV sterilizers, is that the same thing? Do you submerge them in the tank? They seem expensive!

TIA

He is speaking of a UV Sterilizer. This is not a light fixture such as you have.

There are pro's and con's to using one, I'd suggest you read up on them before you run out and purchase one. There is a great introduction artcie written by LoganJ located at http://www.aquariumadvice.com/showqu...q=2&fldAuto=39

Should you decide to purchase on you must understand the minimum and maximum flow rates, else they are useless. And I'd suggest the Coralife TurboTwist should you decide to purchase one.

Algae bloom of some kind.... I would do what the LFS says and keep the lights cut back, stop feeding every day try every other to every 3 days. How old are your test kits?? maybe have someone else test your water.
UV will kill free floating algae..... Do you have acess to a diatom filter? this will clean up the water or usa a magnum filter with diatom powder this will also work .
But you need to figure out why your having the bloom....
Any corals to worry about? Caluerpa in the tank?

I actually just got a new test kit. I was using strips and switched to Seachem. I also had my LFS test water and they said everything was great.

The only reason I went back to my 10 hours of lights is because Mike at Liverocks told me his LR is used to 10 and the 5 hours wouldn't be good for the new rock.

What is a diatom filter? Does it work in conjunction with my canister filter?

I'm not really crazy about buying another expensive addition to the tank (UV ster. or diatom filter) without determining what has gone wrong in the last 2 weeks. I just put $225 of liverock in trying to cure this green water.

We had diatoms a while back, but the water was clear.

Can you get a pic of your tank? It does sound like an algea bloom but you can try cheap fixes first. First course of action...water change. Then try running some GAC and see if it clears the water up. If not, it is an algea problem.

I am at work so I cannot get a picture of it right now.

It is basically green water with some areas of milky white cloudiness.

I am running a carbon bag in the canister filter for about 6 days now. Been doing frequent water changes, with 20% most recently 2 days ago. It doesn't show an ounce of improvement after the water change.

Lando, I do belive it's an algae bloom, but don't know what caused it. Any suggestions on how to fix it? I have read the good and bad about the UV Sterilizers. I wish I could borrow one instead of buy one. What would you do if it were your tank?

I don't understand how the diatom filter works. Is that in conjunction with my canister filter? Does it hang on the tank?

The lights help the algae bloom as well as wter quality issues.

Have you tested the distilled water? Is it possible some bottled spring water was used?

A diatom filter is a special filter that is used with diatom powder, it filters minute particles out of the water and will clear the water. But you need to find the source of the problem or it will just come back.
They run under $100 online.
With that much LR in the tank I would take the rubble out of the canister and run some more carbon and filter floss to help clear up the water. What kind of carbon are you using? Cheap carbon can cause problems.,just a thought!!!

Adding extra LR will not cure the problem only help with filtration. My guess is there is a water quality issue here somewhere. Not all test kits can pickup small traces for silacates and phosphates.
