ok........if anybody cares.......Im finally going to really do this. LOL

I have the powder from GNC and im dumping this crap into my high end SPS dominated 225. Ive had a real hard time bringing m yself to do it just for the simple reason that my first love....the sps are fine........but im simply not 100% pleased with how all of my polyps are looking and have yet to hear any negative accounts.......ive been watching and waiting for them........they still havent come so......

Im going to start with 2000 mg twice a day....ill keep you posted.....
 
Start slow and bring up the dose slowly over a few days like the guide says. You should be fine considering you have a high end system ;).
I have a 220 normal system and started with 1000mg and brought it up to 2000mg over the course of a week and a half. and all is well. i have seen a lot of improvements in the month I have been dosing vitamin C..
 
for a 300 gallon system with only 70 lbs of live rock.......im thinking the 2000mg twice a day IS starting slow. Are we in agreement on that??

Engine 7........did you start with 1000mg TOTAL a day??? Or twice a day??
 
Here's the formula from the article:

Determine the gallon content of your tank.
Deduct 15 % for rock in the tank, more if you have a real large amount of live rock.
Add the content of your sump (if you are using one).
This will give you a net gallonage you need to treat.
Multiply that gallonage by the concentration you need to achieve.
The number you come up with equals the number of milligrams of vitamin C you need to add to the tank.

Day 1 : concentration of 5 ppm
Day 2 : concentration of 15 ppm
Day 3 : concentration of 30 ppm
Day 4 : concentration of 50 ppm
After day 4, continue treating with a concentration of 50 ppm for 10 more days.
 
Sorry, 1000mg twice a day to start. I started before that origional article was out and with over the counter vitamin pills. I went on the recommendation of others that at the time were using vitamin C.
I just meant that thats the dose I was using at first when I started dosing. Flyyguy, you and I basically have the same size tanks. I dose for improvement not because I have a problem btw.

Funny, the one SPS that I have in my main tank (green milli) actually seems to have LESS polyp extension since I started the Vit C. I will keep an eye on it, as it is only a frag.
 
I can't believe the growth on my SPS. It is more a zoanthid-dominated tank, so I don't do much to encourage growth on the SPS but now some of the smaller ones are 3x the size they were before & they seem to have stopped growing at one point or just growing so slowly, I couldn't tell.
 
on topic and off topic. i have been in the hospital for 4 days with Pneumonia and just got out. i read all the post in this thread and when i was there i was put on Vit C. and some other things got me think about this thread. not many before and after pic which this thread can use. i had some 50 polyp frag melt down to nothing a coulpe weeks ago and i have one not opening as well as it has in the past. i will try to get some Vit C. for that rock but not the tank. was thinking about dipping the rock every couple of days to see what happens i will take pictures to report is progress.

If you want to prevent others from potentially overdosing I would stop calling the dosage in the article ppm (Parts per million) as THEY ARE NOT. They are milligrams per gallon if using Thiel's instructions not ppm (miligrams per liter)
One milligram per gallon is only 26% of a ppm so if someone actually uses ppm to calculate the dose as above it will be almost four times larger than Thiel's dose.
 
Thanks jdiek, I've actually been thinking more in the lines of that anyway. We need you here to keep an eye on the chemistry end of things. My husband keeps reminding me that I'm going to have a lot of folks really peeved at me if their tanks go sour because after using the Vitamin C, so lets all at least try to follow instructions, not just dose willy nilly, try to get the buffered VC &
I can't stress enough how important it is to keep a close eye on your pH & alk!

killingseed, Personally, I don't see how a VC dip will help much (especially every few days) but let us know how that goes. Why not just dose the whole tank?

I used to put VITA-C from kent, used dose once or twice a month, but have stopped since and my zoa's some, looking like crap now. So off to DF&S to get more VITA-C.
 
that a good question was looking and didnt see much about how much c is in it.

"Contents:
ascorbic acid (vitamin C) in aquaculture grade form of 2-sulfate dipotassium dihydrate"
 
Well, I stopped dosing C like 3 days after I started because I was having a problem with testing.

The C really threw off my testing of calcium and alkalinity. I use Salifert tests. It really dropped my alkalinity. I was at a dkh of like 8.5, and it dropped it to less than 5 over the course of less than 36 hours. Does anyone think this was because of the unbuffered C? The calcium test is now cloudy. When I add the Ca-2 reagent, the water turns a cloudy pink color. It is supposed to turn a clear pink. When I add the Ca-3 reagent, the water doesn't dramatically turn blue like it is supposed to. It is all cloudy.

The Ca test was working perfectly fine until I started dosing the C. I've brought my alk up to the range it was before, so that is fine, but I'm not 100% sure about the Ca unfortunately.

I've performed 2 15g water changes, and I haven't seen an improvement in the quality of the Ca tests, so I don't think I'm going to be dosing C until I can figure it out.

If anyone has any suggestions, I would definately welcome them.
 
How much C were you adding & for how long? Did you start at 5mg/g like the article suggests? I never noticed ANY fluctuation in Ca (I dose daily) at all. Alk has also stayed steady & I dose that daily also. It took 3 months before my pH droped from 8.2-8.0 & after that I switched to the buffered form.
 
I added 625mg of C twice a day. Tell me if my math was wrong

75g +29g sump = probably about 85g of total water.
85*5*3.785 = 1608mg

I was adding 1250mg daily, so I think my concentration was less than 4ppm.

I don't test every day. Usually like twice a week or so. I only added C like five times (less than 3 days). My zoas have many more polyps now than when I started, so I don't know if the C did it, or if they just grow fast. I'd like to start again to see, but I don't want it to mess with my alk anc Ca.

Where's the 3.785 coming from?
