Zoas in Trouble, Please Make Suggestions (1 Viewer)

You said PPB? Did you mean PPM concentration? I was just reading on it. The standard level says 0.06 PPM according to the article I was reading...

This is awesome feedback!! So I have ZERO sense at all if 46 ppb is actually low or not and could be the cause of my problems. It would be awesome if this is really the issue. I just Amazon'd Brightwell's Iodion. It will be here to tomorrow.

I'm really surprised that I have any trace elements that are low with all of the water changes I've been doing. I've also dosed Brightwell's Replenish a couple of times. I didn't see any improvement so I haven't stuck with it. Maybe that's been a mistake.

46 ppb (parts per billion) is the same as .046 ppm (parts per million). If that is what your iodine level is, that is in the ballpark and plenty good. Replenish is a good trace element replacement. That's what I use. It's nearly impossible to measure trace elements so I just dose according to the instructions on the bottle. My levels always come back in range but any time you dose something you can't test for, its good practice to get an ICP test once every 6 months.

I'm debating what my next step should be. So, whatcha think? Would you still dose a little Iodide at this point or just stick with the Replenish?

One other question first...what are your nitrates? I'm wondering if your nitrate/phosphate ratios might be off...
As far as iodine, based on your levels, hold off for a bit and let's explore other options too...

This is something I have been adjusting for on my tank everything has been much happier now that I’m dosing nitrates and controlling phosphates. I was below 2 on my nitrates and brought them up to 5 and my phos has leveled off at .1 since I started the GFO I still have zoas that won’t open from time to time but I give them a light brushing and a revive dip and they open up after. Sometimes I even wash them in tap water...

I'm having to dose nitrates due to my algae scrubber otherwise they drop below 1 ppm. My target is 5 ppm. My last test showed greater than 5 ppm and I didn't redo the test with sample dilution but based on previous history my nitrates are between 5 and 10 ppm. I will do another test this morning and get you a better number.

Nitrates just tested to be 6.0 ppm using a Hanna tester. I really love the Hanna Nitrate tester BTW. I've already had to buy a refill kit because I've used it so much.

Not as hard to use as it sounds then. It just looked like a pain from the you tube videos I saw. Who is keeping reagents locally? I can’t find them on the southeast side for the ULR phos.

I had to buy my replacement reagents from Marine Depot.

 

[mitchell77546]

I found the ULR reagents on saltwateraquarium.com for $7.50 that’s the best price I’ve found so far.

Update.

I've made a very small initial dose of Brightwell's Iodion (iodide) last night. Based on the concentration stated on the bottle I added 2 ml of Iodion to raise my levels from ~0.04 ppm to 0.06 ppm. Otherwise the recommended dose was 5 ml per 50 gallons every 2 to 3 days, or 1 ml per 10 gallons which would be 6 ml for my tank. So far I have not seen any improvements or changes. I may try another 2 ml dose in the next day or so.

I've also purchased replacement reagents for a Red Sea Iodine Test Kit that a buddy gave me. In addition to the Red Sea Test Kit, I have also purchased 3 ICP test kits from the club to help me figure out what my tank iodine levels and consumption really are.

After a lot of google searches on what iodine depletion can do to corals, the symptoms very much seem to fit how my corals, and which corals specifically, have been behaving. I have my fingers doubled crossed that this issue is really due to low iodine.

If you can think of any other recommendations at this point, certainly please let me know!

 

[webster1234]

You probably mis-typed it but on my bottle, the directions say to add 1 mL per 50 gallons every 2-3 days, not 5 mL. For my 400g tank, I add 12 drops (1 mL) per day and it keeps me about where I want to be.

 

[SCUBAFreaky]

I double checked again, my bottle does state to use 5 ml per every 50 gallons. Actually, I think every batch must be different. Take a look at the concentration on your bottle versus my bottle. My bottles says that 1 ml will raise 1 gallon by 0.8 ppm. What does your state? While doing some homework about Iodion it seems folks were reporting different concentrations of their bottles than what was stated on my bottle. So either they tweak each batch or each batch must turn out differently. For my bottle if you divide 0.8 by the volume of my tank (60 gallons) you get that 1 ml will raise my tank by 0.01 ppm. That's were I got the initial 2 ml dose from to raise my iodine from 0.04 to 0.06 ppm.

Your bottle must be more concentrated than mine. Very curious.

 

[webster1234]

Yea, that's strange. Mine is clearly more concentrated than your is. The concentration is on the bottom of the label. Mine is 15,000 ppm. Yours is probably less than that, probably 3,000 ppm. Wonder if that is something new with them?

 

[SCUBAFreaky]

Your math was right on! Yep, mine is 3000 ppm.

 

[webster1234]

That's what burns me up about these supplement companies. Your's is clearly 1/5 th the concentration of mine and I guaran-damn-tee you the price didn't change.

 

[SCUBAFreaky]

Right?!?!

 

[mitchell77546]

Minimum investment maximum profitability. That everyone’s business model these days!

Just checked and mine is the 3000ppm concentration, or 1ml raises one gallon by .8 ppm.

What’s the expiration date on yours? Mine is 9/21. I wonder if the newer concentration is the higher or lower one.

I just checked their website and they have mention of concentrations. I went to BRS and they list the same concentration as mine, the weaker of the two.
