What is smothering my liverock?

[Subsea]

Respectively disagree... I'm all for testing what I'm dosing but more importantly is testing the affect the dosing has on my parameters. I know the dosing affects ORP so I would want to see any overall reduced level trend or increasingly prolonged reductions. As for pH why would you not expect an increased level to result in a lowered pH? Saltwater has a limited capacity to hold O2 so what other concern would O2 pose at saturation in a reef tank?

You should just do it to prove your hypothesis. Unless your fish load is excessive, I see no reason to expect lower pH with increase of oxygen.

I'll give it a go.
My reasoning around pH is an indirect effect - the higher oxygen level should encourage increased fish respiration thus increasing CO2, I could be wrong.

Higher levels of oxygen should decrease the fishes desire to breathe more/faster as they would be getting more O2 per breath. This works in humans this way, hench why free divers inhale/exhale rapidly before diving to saturate their blood with O2 so they can stay down longer. The increased O2 will probably just dissipate into the ambient air and level off over time. I went deep, I know.

 

[Who me?]

I agree that any O2 after the water has reached it's oxygen saturation point will dissipate.

However, and without going into a long detailed explanation, let me just say that fish respire much differently than humans. Dissolved oxygen is processed via absorption. And the density and viscosity of water is much different than air. Approx 1000 times denser and containing less than 5% as much oxygen as air by volume.

The increased oxygen levels should enable the gill to increase processing thereby producing more bi-product (CO2).

The invader here is chrysophytes.

Would enjoy seeing how peroxide worked with them
These organisms are simple obligate hitchhikers and cannot be generated in any reef that didn't directly import them, and even getting some imported as invisible trace amounts is so rare I've never seen them in person. Various forms of direct kill are indicated

 

[sfin52]

That is basically the exact opposite of what I would do lol.

Agree

Actually the local University lab confirmed this was brown Cyano

nice. Not dino thats a great thing

I am pretty sure brown cyano is chrysophytes. Two different names for the same thing....

I have them as well, trying to raise nutrients. I've done some peroxide scrubbing outside the tank on select rocks with limited success. I have 10 trochus snails, 15 cerith snails, a small pincushion urchin, and a bristle tooth tang all eating the stuff, but it grows so fast. I also can't pull every rock out. Thinking about dosing peroxide into the tank or maybe vibrant. Pretty sure it's screwing up nutrient levels( mostly zero no3, po4 was .1-.15 got driven down all the way to .01) and my sps frags are suffering.

Daily Peroxide dosing direct to tank has been working for me. Almost a week and they have not returned. Corals and fish appear unaffected. I scrubbed the rock while in the tank and bumped up the cleanup crew.

I've also been blowing the rock clean with a turkey baster every evening. To the point where very little detritus is left in the rock to come off each evening.

I've also added a 50 micron filter pad after the filter sock to help polish the water and remove as much as possible

Details? Did you send a sample, microscope pics? What'd they say?

Not sure what details you are looking for? Yes, I took in a sample and they told me it was brown Cyano

 

[brandon429]

hey can you take us an updated pic/tank shot of helped areas we want to link your work in the peroxide thread. also doses/dilution amounts you used

Sure thing, I'm dosing 3mg of 3% daily, total tank volume is approx. 50 gallons

That is awesome. Did you know any one at the lab or go to school there? That was a great idea, if colleges have a need or desire to do ID test like that it would be a great resource. What type of lab, General or field specific?

Yes I know several professors there, it is a bio/medical lab and one of the professors is a close friend whom I've known since my college days. She has a strong background in marine biology though that's not her specific field at this time. They wouldn't do this for just anyone unfortunately.

So you’re saying we should send it to you first, got it.;Joyful
