Video from today - look close - you will spot 4 different pipefish

Hey Lasse,

So you've got the African BlueStripe pipefish. I've got 2 of them (males) with one larger than the other and although they chase each other, they hunt for food separately though. Recently I lucked out acquiring females as I took too long to purchase them from the lfs.

 

[Lasse]

I think that mine is from the Pacific - not from Africa. It looks like there is several subspecies

Yeah it does not have the same vibrant colours as the African specimen. I intend to get a couple more regardless.

Now I got into problem. I have got some cyano among some of my corals. My Seriatopora hystrix and other from the same genus has not done very well for a month or two. Today I could clearly see mats of cyano among the branches. I blow it away - and will do that for a while. It is only among these corals I can see trace of cyano - not on the sand, not on rocks. NO2 is around 4 ppm and PO4 shows 0.2 ppm. NO3 is where I want it but PO4 should be taken down a bit - 0.05 - 0.1 is the values I want. A month ago I lower my peroxide dosing again - was up to 12% and 2 catalyst but when I come back after vacation in June - I put it down to 2 catalyst and 6 %. it did not help obviously - therefore I rise the dosage to 12 % and 3 catalyst. I will see what´s happen. ORP - that use to be around 340 is now altering around 280 mV. I also put my skimmer to skim more wet - it has been very dry. The cup has been on since June. I also change my flow a little

My torch seems to recover - but yesterday it start to be kinky again

I will update on this.

I upped my H2O2 from 6% with 2 to 12% to 2 and I credit it with helping reduce my cyano. Might be too early to draw a connection but now that I have an oxidator I wouldn't run a tank without it. If for no other reason than the tank just smells better.

 

[Ardeus]

I went from 9% to 12% and my anemones didn't like it at all (2 catalysts).

 

[Sallstrom]

What I've seen with Seriatopora corals in the tanks at the museum, they often struggle at high phosphate levels. They might grow well for a while, but often die fast.
For the Cyanobacteria, is it only on newly bleached coral skeleton?

Just wondering do you normally run NO2 at those levels?

 

[Brew12]

I'm pretty sure he meant his NO3 are at 4ppm, not NO2. I think that was a typo.

 

[najer]

I also change my flow a little

I have thought about this over a few years, our tanks are nearly the same age, both a step or two off the generally trodden path!
I don't like your flow, I can't be doing with the back and forth flow, how much did you change it please?
I love random flow.

Typo - I meant NO3 as Brew suggest.

I think your right, but Lasse May have some secret magic, lol. The main reason I was asking is I have read that some nitrate reactors if they stop working perfectly can cause rises in NO2, and with his RDSB i was just wondering, hopefully incorrectly.

There is something with peroxide and anemones - but I´m not sure if it is the peroxide itself or the higher average oxygen level they react on.

My standing waves mix the water much better than a random flow from the same pumps would do. It means that it will give around the same oxygen level even around the corals when the photosynthesis is optimal (the coral will be rid of surplus oxygen faster). Backside - no direct flow force at places there cyanobacteria can thrive. One of the sites for cyanobacteria in this case is in front of the flow from one of my wavemakers. It will give a steady high flow during max photosynthesis now and waves as usual during most of the day.

No bleach of these corals - just mats

It will be a Triton test to send in tomorrow or Thursday

I hope this will happens too - but it is probably an overdose for me. I have to look up.

Sincerely Lasse

 

[Lasse]

I have get these two as different species and the feeding behavior are different - they are probably different species.

​

By the way - in the background you see one of the cyanobacteria infested hystrix colonies - and in front of him/her the second.

Cyano has been shown to be considerably more sensitive to h2o2 (likely ozone too) than other classes of organism.
I'm a little surprised it showed in Lasse oxydator tank at all, but in concert with lower ORP I guess it's possible. I interpret that as the peroxide has a larger abundance of targets in the water itself than usual.

 

[Lasse]

I blow it away yesterday - normally it would be as much as before the day after - not in this case - there was some very small patches left - and they get a blow today. No cyanobacteria in the refugium. ORP slowly up to around 320 mV as highest.
