Sugar in a FOWLR

After doing a lot of reading on reef central about sugar dosing, I decided to start doing it on my tank. My nitrates are a bit high at 30 PPM as I've been adding a lot of food to my tank trying to see what my Puffer would eat(and apparently its just ghost shrimp for now) and my skimmer was also down for like a week so that didn't help either. I added a half teaspoon of sugar and I'm going to forego my normal weekend 10% water change to see the effects. I'll update in this thread.

Any reason you went with sugar over vodka? (Other then just having sugar or not wanting to waste vodka lol)

That's interesting putting sugar in salt water. Complete opposites.

Most puffers will eat anything that resembles food, how long have you had him? I assume you're not keeping inverts, because of the puffer; if so, 30 ppm of nitrate is a perfectly healthy reading and nothing to be concerned about, IMO.

Vodka speeds up the breeding process by reducing inhibitions.
Expect to have lots of fish babies soon, if you use vodka dosing.

I've had my puffer for a week now. Right now he only eats ghost shrimp. I bought him 2 days after my lfs got him and he wasn't even eating there. They had ordered him just for me(the one i had wanted that they had was sold a week earlier). So I ignored my better instincts telling me not to buy a fish not eating yet, but he seems pretty happy in my tank now. I just added as utube mod to my mrc skimmer and its pulling out a fair amount of crap. I'm going to test my nitrates tomorrow to see where they're at. There are some inverts in my tank, a peppermint shrimp and some hermits, as well as a ton of small featherdusters, but they were hitchhikers on my live rock so I know they are potential food.
I'm not concerned about my Nitrate levels, i know my Puffer is fine with this amount, just having a decent level of Nitrate was a good opportunity to test the effects of sugar dosing on said levels.
If you want to see the main thread i read at --, just pm me and I'll send you the link. Sugar or vodka promote bacterial growth which feed on nitrate and phos, the primary danger is that the rapid growth reduces o2 in the tank, so its not a good idea to dose unless you have a skimmer and good flow. You also need to be sure to start dosing in small amounts. Another danger is that you can reduce your nitrate and phos levels so much as to be a danger to corals that need low levels of these chemicals in the tank, but i have no corals. I went with sugar over vodka because I didn't see any advantage to doing one over the other and I have sugar readily available.

I read quite a bit on this and am going to try it in my no LR "retro" tank after the next water change. My nitrates in this tank hang around 60ppm; although I haven't tested it for months. I know this doesn't hurt the fish; but along with phosphates & silicates, contribute to an occasional diatom problem. I've tried a lot of things looking for an "easy fix" and was ready to go with a DSB or elaborate home-made " LR rubble reactor" in another, larger "retro" tank. I'll let ya'll know what happens.

A few inverts and a 3" Porcupine Puffer are all thats in the tank now. This is my log so far:
Day 1: 30 Nitrate 1/2 Teaspoon
Day 2: 1/2 Teaspoon
Day 3: 20 Nitrate 3/4 Teaspoon
Day 4: 3/4 Teaspoon
Day 5: 3/4 Teaspoon
Day 6: 15 Nitrate 3/4 Teaspoon
Water volume is about 175.

I have heard about both sugar and vodka. I don't care about vodka, but the lady might give me a smack if I'm adding Ciroc to my tank. It's bad enough I use her cutting board, knives, blender, and measuring cups. So I'm interested what do people add per gallon of sugar and vodka, and what frequency? Thanks, Tim

My nitrates in my 55 retro were at about 80ppm. I used 1/4 tsp sugar and they were down to about 60 within 18 hours. I got advice that said to use about 1/8 tsp per 25 gal every other day' then about weekly after they've come down where you want them. I'll add sugar tonight and test again tomorrow night. I found some real positive feedback from folks who really seem informed on this...I'll keep posting until it works . (or a major problem develops, which I doubt: I just don't like adding anything I can't test for...although sugar is so common in so many forms that I would expect it to break down harmlessly. But, I am not a chem major.

So you are saying that sugar will help reduce nitrates? Where did you find this information at would like to know more about it

See post #1 or #8 on this thread, that's a starting point. Not playing games, but we can't post links to competing sites. PM me if you need to, I got the link from another member and there's tons of info.

This sugar thing seems too good, my nitrates in this tank have gone from about 80ppm to about 50 ppm in a few days. I know nitrates test kits are generally very "iffy" at best; but I had mine "calibrated" by a pro and am sure my readings are very close. When I get to 30-40 ppm; I'll go to weekly dosing. I've been following another thread at another site and this seems to be the real thing. I still haven't seen or heard a downside to the sugar.

Any drawbacks on this dosing? Some of our reef club members have gone the vodka way, but I haven't seen anybody with sugar yet.

I have the only dangers I'm aware of listed above:
the primary danger is that the rapid growth reduces o2 in the tank, so its not a good idea to dose unless you have a skimmer and good flow. You also need to be sure to start dosing in small amounts. Another danger is that you can reduce your nitrate and phos levels so much as to be a danger to corals that need low levels of these chemicals in the tank
Also I haven't seen any differences between sugar and vodka.
