CORALS NOT LOOKING GOOD

jmcdona6 · Aug 10, 2020

I think running some carbon and water changes would address, if only short-term, the toxin and high mag issues (if it is really that high).

where would the toxins be coming from as far as water changes my salt mix is already high in magnesium so would help on part but be bad in another

What products remove just phosphate? I'm not aware of any.

Brightwell Aquatics Phosphat-E. It binds to the free form of the molecule making it unavailable for biological uptake. The inert phosphate may then be permanently removed from the system via mechanical filtration and or protein skimming. It works very well and almost instantly. Had great success with it.

Are your RODI filters clean? If you haven't changed them in a while I would suggest doing so that could be where some of the toxins are getting into your tank. Also running carbon will help pull toxins out of the water. But you need to figure out where they're coming from to solve the underlying issue. Again I would do and ICP analysis to get a bigger picture of exactly what these toxins are.

K so as far as the mag how do I lower it my salt mix is to high as far as the mag

Try switching salts. Every brand has different levels of elements so with some research you could find a brand that suits your needs.

That’s what I’m doing also plan on adding a refugium not sure if it will help what do u think

Go for it. Refugiums are awesome! I always ran them on my Nanos. Just upgraded mine to a 19" from a 13" last week as a matter of fact. I have a Youtube channel and videod the whole upgrade, I'll get it edited and uploaded soon and send you the link. Should help you in setting it up.

I don't understand. Lets say your magnesium is actually 1700. If your fresh salt mix is 1500 or lower like most are, any water change will dilute that down and eventually get to 1500 overtime. The only way it makes it worse is if your fresh salt mix is greater than 1700.

In any case, the easiest way to purify/balance aquarium water is to replace it with good water. This, of course, assuming your water is good. I just noticed you said you are using ESV salt mix. Are you sure you are mixing it right and not adding too much magnesium additive? Would certainly explain some of your issues. Also if magnesium was dosed incorrectly you can probably assume some of the other elements of the mix are off as well. If the salt isn't mixed well it can also throw off your other tests. For example, too much magnesium can tie up carbonate in the water making it unavailable to your corals. The tests still detect that it's in the water, but it is completely inert.

High magnesium in the short run is not a big deal. But keeping your tank at 1700 magnesium over the long term will negatively impact coral growth and stress them out.

Your magnesium is not the problem. The only way to reduce magnesium is with water changes with a mix lower than your tank.

How to remove toxins would be another question

Depends in the exact toxin, but activated carbon, skimming, purigen, and other organic binding products may be appropriate. Water changes too.

Toxins in this context means organic compounds released by organisms such as dinos. Salt mix is not a source.

using tropic marin pro reef contacted them today in regards to the salt being above 1500 i have esv on hand if i needed to use it but prefer not to start messing with different salts unless i have to

jose hernandez · Aug 10, 2020

so to remove toxins water changes and more carbon? also can i use chemiclean noticed some of the rocks on the back have a redish color on them took a turkey baster and started blasting them so far twice today

yes on carbon and water changes. I would not add an antibiotic treatment (chemiclean) into this mix. The dead bacteria may also release toxins.

jose hernandez · Aug 10, 2020

as far as my salt it being over 1500 in mag do i just use the esv?

This happened over two days?

How long was the tank running happily before hand?

Do you keep weekly water chem results?

What have you done differently in these two days?

I don't agree with the assertion that lanthanum binds and removes only phosphate. The soluble lanthanum will precipitate carbonate and the precipitated materials will bind metals and organics just like GFO.

Brightwell is not a good source of chemical info.

" Sorption behavior of heavy metal ions such as Cr(III), Mn(II), Fe(III), Co(II), Ni(II), Cu(II), Zn(II), Cd(II), Ba(II), Hg(II) and Pb(II) studied in different aqueous systems shows that the prepared mesoporous lanthanum phosphate is an effective adsorbent which may be used for their removal from aqueous systems and also in presence of different complexing agents.

its been longer than two days as far as water changes every two weeks figured it was my lights at first after i changed them and ramped them up so i changed them again because i noticed the corals werent doing good and noticed the algae figured it was the lights so did a water change and then thats when i started to be concerned

jose hernandez · Aug 10, 2020

ive used gfo in the past but it completly strips the tank ive had it happen to me before in my previous tank on this one im only using skimmer a bag of carbon and a 8x8 marine pure block no refugium i was thinking of setting it up
