Oxygen saturation in tank water

[Heather w]

I have recently had an outbreak of a little known bacterial disease called White Slime Disease. Probably gets its name from the white slime it produces.

One of the side affects of it is that it binds the oxygen in the water and my fish all drowned.

Treatment has been tedious and has tried my confidence like you wouldn't believe. I have 1 eight line wrasse left and he keeps my eye on the prize.

The issue now that I have this thing on the run is, how do I know if there is enough oxygen in the tank now? I know there is a way to measure it and I briefly saw a thread here but can't find it now.

Can anyone out there lend me your guidance? All of you seem to be so knowledgeable. All the acronyms have me puzzled and make me feel stupid but I'm sure I'll learn it all

Are you running a skimmer? maybe run it and some airstones only until the algae subsides.

 

[brandon429]

Not agreed the growth causes death by loss of oxygen the exchange is rapid enough in typical tanks that it's not the causative

I remember a coral magazine study on it from about 20o5 regarding air fresheners causing it

The respiration rates of the fish outpace the oxygen command of filter feeders and sponges and slime molds. Agreed large bacterial outbreaks are oxygen consumptive but it sure has to be a lot I'd be curious to see invasion pics

So many photosynthetic points are producers during the day inside a typical reef tank, the turnover sufficient during the night + skimmers good call that's not the causative I'd agree too it would be allelopathic or not related other than direct poisoning from whatever variable not IDd

Its a shot in the dark honestly. I had a similar thing happen with my doser running wild and dumping nopox into my tank. Killed all of my fish but everything else was fine.

 

[morpheas]

Well salifert had a test kit. Also, at a ridiculously high price tag apex has module pm3 (which is normally priced) and probe (which is the ridiculous part).

 

[Heather w]

It was, I believe the air freshener. When I get my water up for a WC I set each bucket near my refridgerator. And the auto sprayer was where? Yes, on top of the fridge. I never gave it a second thought. I finally have it breaking up but I was having to wash EVERY FILTER every day! That's how bad it was.

 

[Heather w]

Unfortunatly. The treatment for this slime; and that article written by, (Ictonischo?) is the only one I found other than the one he wrote with dr. Tim. Anyway the treatment stripped my tank of a lot of my good bacteria and algaes. BUT, hey. My nitrates are 0 and my phosphates are 0. I need to get more bio load but don't want to if they're just going to drown. My 8 line is just fine. I lost a huge pulsating xenia. But my non pulsating is still doing well. This picture was taken when it was half gone. The purple algae just died and then the coral had no "root system".

 

[Heather w]

Thank you all! Where should I go from here? Any ideas as to adding bio load

 

[brandon429]

theres no need to increase your bioload unless you want the extra animals and feeding, I run a coral only low bioload system without fish and its easy to keep runs well. that pic above looks totally normal reefing/coral health.

I have run Oxydators in my tanks for the last 25 years or so, no lack of oxygen ever in any of them. No electricity, no pumps, easy to use, safe, cheap to buy (relatively speaking) and very safe. Keeps my oxygen levels at optimum at all times.

 

[Heather w]

I am just so discouraged. This is what has been coming from the tank. I don't see haw they survive. Good news my nitrates are 0. In treating this sludge I have killed everything in my live rock.

 

[brandon429]

do you have a pic of it underwater, trying to make sure isn't chrysophytes group of invaders

 

[Heather w]

That's the thing. In the water and on the glass and rock. it appears white. On the filters it's green. My tank was teeming with life. I would sit for hours just lost in it. My magnifier app and I took amazing photos of life forms. I watched them bloom and grow. Now it's just devoid of micro life. Like a new tank other than the one one xenia. I know everyone swears by the hydrogen peroxide but it kills algae. All algae. Even the good stuff. I miss my tank and having life grown right before my eyes. Now I don't even have atapastia. And the H2O2 didn't touch the green hair algae. I really appreciate everyone here who helps us newbies

 

[brandon429]

Agreed the peroxide can attack most algae and for your green hair algae you still have other options for it to rid it

The micro life and stars and pods will come back for sure populations will wax and wane in the tank based on changes, it's a hand guiding/farming process you can get them all back in steady state with good feeding once the offender is beaten
Everyone will have their approaches to try, mine would be a thorough hand cleaning of the invader from all surfaces then uv light vastly oversized, pond sized, ran temporarily until beaten. There are specific physical characters of your invader vs others that indicate uv as a potential.

That will beat your hair algae without fail. That thread doesn't take into account the hard work of the job, or if someone wants to do the work to make up for purposeful algae farming-it's only a method to win among many. Most times the keeper doesn't really want the algae gone that bad, they will select options that do not have two hour turnaround times for the easier/ no work possibility

 

[Heather w]

I fuss with my tank for pleasure. You're talking about scrubbing off the hair algae by hand in a bucket of tank water right?

This photo is from just now. This morning I cleaned the fans off with a paint brush.

The articles I referred to is from Coral Reef. Mystery of the White Slime by Lance Ichnotsubo.

You can also see it clinging to the hair algae

 

[Heather w]

I ordered the Re-fresh. It got in today.

 

[Heather w]

Brandon. I have 3 little sps on the most infected rock. I have no problem rasping away but I don't want to hurt the coral

 

[brandon429]

they can take brief exposure time to work externally, but id prioritize the large invasion first before compounding actions and stressors agreed. when you are dealing with just the gha part that w be a reasonably safe time to give a small area a test go, no need to try and wipe it all at once

 

[Heather w]

I am hopeful that this medicine will help the Dr. Article said after a few applications I should see some improvements. It will be so nice to look at the tank and not have to worry about. The chore. You have been invaluable. When I get home I'll look at rasping it.
