you got a problem

BUMP

Your tank is just delightful.

🤑

I really like my gyre/wav combo. I have two gyres on the ends of the tank and then two wavs on the back of the tank. tunzes could fill that same role.

It works, just not on corona.

My stash of CP just became that much more valuable Now its not just for treatment of every marine fish disease. People are getting in on the action. https://www.ncbi.nlm.nih.gov/pubmed/32074550

i like everything about this.

nice

So the idea here is instead of forcing a chamber to become anaerobic, that the center of the passive columns become anaerobic on their own, both from outside the column to inside, as well as from the surface of the media to the inner layers of media. So far I am relatively sure that its functioning well, as I'm only limited by my ability to accurately test nitrate. Its dropped me from 10-5 ppm, and there is definitely some alk consumption going on specifically from the sulfur media. I honestly think that the possibility exists that we are over-mechanizing this process, at the behest of those who wish to sell us reactors

I wouldnt use a return pump as a wave maker personally. You still have some water movement if you add in a circulation pump in addition to a return pump. You can get a jebao very cheaply if you just want to dip your toe in the controllable pump water, so to say.

they have some that dont even require electricity. https://www.bulkreefsupply.com/flow-lok-leak-detector-for-rodi-systems.html

link to the AD sale site? any photos of its location?

The gold standard for ATOs are the tunzes, specifically the OSMOLATOR UNIVERSAL 3155 AUTO TOP OFF. I know its a bit pricey, but replacing your fish/corals/floor will certainly be pricier. Keep your eyes open for used deals on these, as they come up from time to time.

personal preference really. its a little hard to say without seeing your setup, but i prefer socks or sock derivative (cups with floss/media)

sweet summer child....

I put in 500g of sulfur prills in a filter sock in my sump. Not under the overflow, but just passively sitting in the first chamber. One side effect of this is that alkalinity is consumed, so I measure alkalinity every 30 minutes until i get a better handle. My nitrates are not very high atm (10 ppm), and I also have some gfo in a bag in my sump as well to deal with po4. Should be interesting! Most sulfur denitrator reactors run in combination with limestone media to buffer the h+ released (lowers pH) and release some bicarb (alkalinity) which is consumed by bacteria to change nitrate to nitrogen gas. I'm not doing that, because over time you get increase in Ca, which is consumed relatively proportionally to alk. So I monitor the alk and dose accordingly. I really dont have any idea how much the consumption will change, because right now my tank is consuming zero. The basic theory here can be read in detail here ; http://www.baharini.eu/baharini/lib/exe/fetch.php?media=badess:182.pdf 2 H2O + 5 S + 6 NO3– → 3 N2 + 5 SO42- + 4 H+ Sulfur + nitrate are used by bacteria to produce nitrogen gas, sulfate (abundant in saltwater, probably not an issue) and protons (which are an issue). Protons decrease pH and combine with carbonate and reduce alkalinity. SCIENCE

So just to follow up, I got the KHG, and I love this thing.... I dont have any consumers of alk in my DT yet, BUT i am about to start a little experiment with sulfur denitrification in, which will be an alk consumer. So... all in all, the KHG is a winner for mr so far.

I mean he's ok.

Pricing discussions are probably best kept to private messages.

ohhhh good point. maybe chloramine? do you have any clear photos of the fish that makes you think there might have been a disease issue? the black ich?

If you leave the tank fishless for long enough, then you should be ok assuming the fish that you have in QT is treated. There is some debate about how long that period actually is, some say its up to 76 days, but thats based on some very old science. However, it might be worth it to stay disease-free in the future. Its also important you keep your QT either covered or far away from your display, as disease can transfer via aerosol. the two medications i listed will take care of must of the nasty pathogens capable of infecting fish (separately, not combined). Check out humble.fish forum, he has lots of good information about fish disease and quarantine.
