Put too much sugar in tank

Another poster advised that I could put 2 spoons of sugar to get nitrates down. I thought he meant table spoons.

Anyway I put in half of what I thought was his recommended dosage. 1 table spoon (3 teaspoons). I also mixed 2 small capfulls of vinegar.

I have 90 net gallons, a bullet 1 precision marine skimmer with a magdrive 12 pushing it. Also open top.

I did this about 10 hours ago. There is no visible change atm. None. Even the skimmer is working totaly normal.

When does the big bloom usualy occur? Am I in the safe zone now?

What 'big bloom' or 'safe zone' are you talking about?

I doubt that you'd get a huge response from dosing a couple tablespoons of sugar in 90g of saltwater... I've never heard of using vinegar in a reef tank.

If your nitrates are high, try more frequent water changes & improving water circulation (i.e. adding some Koralias or powerheads).

You DO NOT want a bloom. You will deplete all oxygen out of your tank killing everything inside of it. Here is the way you want to dose

Also you can read this post about the bacteria bloom

take it slow.

I've never heard of using vinegar in a reef tank.

Vinegar is widely used along with limewater (to limit the pH rise and to help dissolve more lime), and it will drive bacteria in a similar fashion to other organic carbon sources. I discuss it here in the limewater context:

What Your Grandmother Never Told You About Lime
http://reefkeeping.com/issues/2005-01/rhf/index.htm

from it:

http://www.reefkeeping.com/issues/20...hf/index.php#6

Vinegar And Limewater To Reduce pH

The reason that limewater raises the pH of aquarium water so considerably is because of the hydroxide that it adds. As described above, the hydroxide can combine with carbon dioxide to form bicarbonate and bring the pH back down. In many aquaria, however, the aeration is not great enough to bring in carbon dioxide fast enough to meet all this demand, and the pH rises. There are several ways to add additional carbon dioxide to meet this demand, including delivery from a carbon dioxide cylinder. Many aquarists, however, choose to add carbon dioxide in the form of vinegar. Many of them choose to add the vinegar directly to the limewater, although if pH reduction is the goal, it can also be added directly to a high flow area of the aquarium.

When vinegar is added directly to aquarium water, the active ingredient is acetic acid. The first thing it does is ionize into acetate and H+:

6. CH3COOH ---> CH3COO- + H+

Bacteria can then metabolize the acetate to gain energy in the reaction shown below:

7. CH3COO- + 2O2 ---> 2CO2 + H2O + OH-

On balance, the H+ released in (6) and the OH- released in (7) offset each other, and the net addition is simply carbon dioxide:

8. H+ + OH- ---> H2O

9. CH3COOH + 2O2 ---> 2CO2 + 2 H2O

One of the potential side effects of this metabolism is that the bacteria performing the transformation may grow faster because of it. This growth may have positive or negative outcomes. One potentially positive outcome is that as they grow, they will necessarily consume nitrogen and phosphorus, possibly lowering nitrate and phosphate levels in the aquarium. Another is that the bacteria may be a suitable food source for other organisms.

Potential drawbacks can include reduced oxygen as the bacteria use it to consume the acetate, and the appearance of unattractive bacterial mats in the aquarium (reported by some, but not by the majority of vinegar users).

Vinegar And Limewater To Boost Limewater Potency

Another potentially useful attribute of vinegar is that it can be used to help dissolve additional solid lime into limewater. It does this by reducing the hydroxide concentration in the limewater:

10. CH3OOH ---> CH3COO- + H+

The H+ combines with OH- in the limewater:

11. H+ + OH- ---> H2O

The actual dissolution of Ca(OH)2 is limited by the multiplication product of the calcium and hydroxide concentrations in the limewater as shown below:

12. Ca(OH)2 ---> Ca++ + 2OH-

13. [Ca++] x [OH-] x [OH-] <= 5.5 x 10-6

where [Ca++] is the concentration of calcium (in moles/L) and [OH-] is the concentration of hydroxide (in moles/L). Consequently, if you reduce the concentration of OH- via equations (10) and (11), then more Ca(OH)2 can dissolve into solution and still meet the equation (13) requirement.

This would seem like a concern, however, since losing OH- might reduce the amount of alkalinity delivered by the limewater. Luckily, this is not the case. While the OH- is temporarily reduced by the acetic acid in the vinegar, when bacteria metabolize the acetate, they release it back to the water:

14. CH3COO- + 2O2 ---> 2CO2 + H2O + OH-

Consequently, additional solid lime can be dissolved into limewater using vinegar.

How much can be used? The more vinegar that is used, the lower the pH of both the limewater and the aquarium will be. One reasonable point to shoot for is to add about the same amount of total CO2 via the vinegar as is needed by the lime to form HCO3-. This balance is roughly matched by using three level teaspoons of solid lime per gallon of limewater, and 45 ml of vinegar per gallon of limewater. For those aquarists choosing to use vinegar in limewater, these values are a suitable starting point. Note that the pH of the limewater is still quite high, so slow dosing is usually required.

What kind of vinegar should be used? Luckily, cheap distilled white vinegar is likely the best. More expensive flavored and colored vinegars, such as red wine vinegar, will deliver other unnecessary organic molecules to the aquarium, and are best avoided.
