Hi there Tony - REALLY NICE looking tank there mate! How long have the tank been running for?
I have a 2 metre tank, with a total water volume of +-870 litres. I am running 2 x TS2 skimmers on my tank.... You are running your metal halides for quite long - 10 hours....
Interesting that you would have decided to use the T5's as the "White light" with the metal halides supplying the "blue light".... usually people do it the other way around - with the metal halides supplying the "white light" and the T5's the actinic/blue light...

Another thing - you only have a total of +-18500 litres per hour water flow in your display tank. That is quite low for a SPS tank (even though your tank has a lot of softies and LPS in as well).....

Do you have a DSB in the tank? In the sump?
I see you have macro algae in the display tank - at the back.... you do not have problems with these, do you? Overgrowing corals etc?

The tank was runnignfor three years as a four footer till I transfered all to the current six footer. Mikaeel, the skimmer works like mad especially with the vodka, sugar and Prodibio additions.

This is the skimmate after twenty four hours

It is a bit low, but the missus loves those LPS and softies and I'm getting rid of them slowly. Also waiting for the hydor pumps. Those puppies pump 12000lph each.

Do you have a DSB in the tank? In the sump?
Have a DSB but I cant get it to work. The prodibio does the job for me. Tried a plenum but that never worked.
I see you have macro algae in the display tank - at the back.... you do not have problems with these, do you? Overgrowing corals etc?
I think thats the silly background that I have for the tank with all the bleached corals and caulerpa. Looking to change that soon but I don't know to what. I used to have a big problem with hair algae AKA derbesia but that's all gone thank to Prodibio. Sherbet I sound like a rep for them.

Irshaad.

Sugar, vodka or vinegar are all natural forms of carbon which feed the bacteria to break down nitrates and phosphates. A good skimmer is imperative for this to work properly. The thought is to use many different forms of carbon as it is believed that one form feeds only one strain/type of bacteria. Some guys even use all three to really get the max out of their system. Check out reefkeeping.com for an article on vodka dosing.

Ziyaad, good to see you this side.

A stunning healthy looking tank Tony. That has to be the biggest bubble i have ever seen. In pic two on a ledge above bubble and shrimp...looks like a Sunburst :)(Tubastrea) ? If it is ... i would put under ledge and place an sps frag in that spot... Great real estate for a light loving specimen.

Copy JB on the light issue. Running 3 x 20 000k Halides IMO does not generate enough PAR (photosynthetic available radiation) for the sps. But saying that , i could be wrong, as your tank does look the picture of health.

Sunburst. The corals don't grow as fast as I would like them to but I have a monti frag that has doubled in size in just over a month. I'm going to move the sun coral under the pincushion. They don't mind the light but as you said it's wasted on a coral that doesn't need light. The nice thing about the 20000K halides is that they colour up the corals better than lower kelvin bulbs.

Thalion, I'm just following the instructions on reefkeeping.com and haven't had any negative impact on the tank in fact it's looking better than ever. The article doesn't advocate a rush job but one should slowly increse the dosage till the nitrates/phosphates are zero, then slowly drop the dosage till the nitrates/phosphates rise to get a maintenance dose. I only add 1.3ml of vodka a day. Half in the morning and half at night.

Tony, I think Thalion is referring to the newbies not to just head out and start dosing Vodka. Research has to be put into it, and from what i see, you know what you doing :)

Mekaeel is correct, too many people think it is a quick fix. I have tried it on 2 tanks 1 was fine but the other, well lets say is had a bad reaction.:(

Did you get an algal bloom or a reduction in oxygen?
