The white film is good aslong as it doesn't turn into a white cloud. It is the bac that is accomplished from carbon dosing.

How about white strings? Ive got a TON in my sump all over my equipment. Corals are looking healthy though. I know its recommended to cut dosage in half if this becomes visible but if I don't and continue my dosing regiment will the white strings go away??

Hi..

1) Bacterial Blooms (slimy white strings) = too much bacteria, decrease vodka dosing

FWIW, when I tried vinegar, awhile back, it got worse not better.

I'm beginning to think it is just old tank syndrome. A tank that has been set up a long time is bound to start having these issues. I'm sure there is another answer, just have not found it yet, no matter how much I read.
I've had the same experience and I started low dosing of MB7.Now a couple months later the cyano has cleared up,no more cyano.

OK, I've slowly backed all the way down to about 44 ml per day, spread over the daylight hours. Things look much better. I did not realize how cloudy the water had gotten, presumably with suspended bacteria.

The RBTA's are largely back to normal, but I did loose one that I'd had for only about a month (not sure if that is related or not, but it could well be). The H. crispa seems back to normal.

The cyano is largely gone.

The green algae on the glass is growing more slowly again.

The soft corals are expanding fully again.

All in all, looking good, and I may add some new livestock (anemones and/or fish) in the next few days.

Randy, good to hear things are back to normal.

I noticed when my nitrate hit zero using a Salifert Nitrate Kit, I had to back off on the amount of vinegar I was dosing by about 1/2 due to increased bacteria growth. I'm curious if this is the same for you?

I don't understand why bacterial growth would increase when nitrate hits a very low nitrate & phosphate reading? The same has been reported with vodka.

I don't know why that would be. I started with low nitrate last I measured, so I can't really say how it has changed during dosing (and I've not tried to measure nitrate once since dosing).

One possibility that comes to mind would be a switch in bacterial species that are braking down the ammonia, nitrite and any nitrate (if it makes it to nitrate). At least that was reported in the one article I had noted. When the levels of nitrate and nitrite change, so did the bacterial. I just remembered that.

Glad I found this thread. I didn't realize that cyano came with overdosing. My bioload is non-existent as I had an ich outbreak so I only have snails. I am on week 4 of vinegar dosing and only doing about 25 mls a day. But I now start to see Cyano which I never had before. I guess I need to back off that a little bit too

Tank is 100g

Backing of is a fine plan, but your dose is a lot lower than mine.

Hello

What would be your recommendation for initiating vinegar dosing? My goal is to control phosphates and use less GFO. It's a 300g total volume softie system that runs on a ETSS 1400.

I would like to mix the vinegar in my kalk solution. Twenty gallons kalk water is prepared every 4-5 days with a 3g of evap replacement a day (I know, huge = Zeroedge connected to the system).

How much vinegar should I add to the 20g of prepared kalk?

Thanks

I don't prefer to add it in limewater because I prefer to add it during the daytime only (when O2 and pH is highest), but many folks do add it in limewater.

I'd start at 20 mL per day and ramp up to 50 mL per day in 2 weeks. Then decide based on how the tank looks whether you want to raise or lower the level from there. Determine how much limewater you add each day and then multiply it up to the 20 gallons you make at once.

Randy- what's the benefits of lime saturated vinegar? Is it to reduce the ph lower effect when vinegar dosing?


With lime saturated vinegar, will there be substantial amount of Alk/ca added? I'm currently dosing Alk/cal/mag via dosing pump and all parameters are stable-

It is primarily to reduce the pH impact when first added and especially if added obnce a day manually.

I currently dose vinegar without lime using a dosing pump, although I have done it with lime in the past.

The amount of calcium and alkalinity added is fairly low, but perhaps useful for some folks. It is much lower than in the limewater you'd get with top off.

Thanks Randy- I think I'll just keep with my daily doings of 24x a day. In your opinion, better to dose during daylight hours or constant food source for bacteria? I use to manually dose during daytime, but I added the t-02 doser from bm and that doesn't allow me to dose only during daylight hours-

I dose during the day to keep the O2 and pH effects lower.

There's no need for bacteria to eat 24 h a day.

But 24/7 is probably fine too if it is spread out.

Hi Randy ,

I'm building a new 154 g system and i bought a 3 channel dosing pump , to dose CA (1) , Alk (2) and i'm gonna try to dose vinegar with the third channel.

But on my nano i had only two channels and when i mixed my Ca additif with vinegar i whitnessed (after a coupple of weeks) black slimy strings in my Ca / vinegar container , even blocking the dosing pump...

Did anyone whitnessed the same effect , does it occur when only dosing vinegar with a designated pump / channel ?

greetingzz tntneon

I would not store reservoirs of diluted vodka or vinegar for that reason: bacteria will consume it and grow in the holding reservoir.

Limewater is different because the high pH stops bacterial growth. But a calcium supplement may not. FWIW, I dose vinegar straight from the gallon jug it comes in. There is no concern with bacteria growing in that because the pH is too low for growth.

Thx Randy ,

-That explanes it very clearly .
Will dose it directly out of the bottle (1 L ) with my BM-T01 dosing pump , hopefully i can dose it only in the daytime (see kenith's post).
But i don't think it would be such a big problem as i'm now still using BP's in my nano , and that is also an 24/7 carbon dose i would guess.

Ok I wanted to start dosing my no3- .2 and my po4- .04 mostly sps few lps which would be better source of carbon vodka or vinegar?

I'd suggest vinegar, but both can work.
