Metal Removing Resin

Using Metal Removing Resin in addition to Carbon and Bone Char to remove metals from my tap water.
There are different 'brand's' of metal removing resin but nearly all are a variation of C107E made and supplied by Purolite.
www.purolite.c...
Which was designed as an alkalinity removing resin for drinking water.
but also was found to have a high selectivity and preference for metals.
After absorbing and becoming saturated with carbonate ions, will swap them in preference for metal ions.
The metal removing Resin I am using is from RO-Man

Hi Dave very informative enjoyed, all the best Jiffster 👍🏼👍🏼

[@DavesKoiPond]

Thanks, 🙂
Just my seemingly never ending quest of better water quality 😄

[@simonshears5182]

👀ing with interest 👍🏻

[@DavesKoiPond]

Thanks, 👍
i'll update in a couple of weeks to see if there is any positive impact.

Watching with interest 🧁 filter house looks like a science lab 🧁👍👍👍

[@DavesKoiPond]

Cheers mate, 👍
It's either the science lab, or admit my tapwater has changed so much it is now completely poisonous to koi.
And move a couple of hundred miles away to get better water...not sure which is cheaper lol! 😄
More sciencey things to come soon... 😉

Great videos, thanks, when dosing with sodium thiosulphate my copper drops dramatically which is good, but after a period of dosing noticed it jumps very high. I have read sodium bicarbonate reacts with copper sulphate to leave copper, not sure if this is correct, however it would explain the jumps in copper in my pond and mean two dosing together would not be possible. Love your videos and I have used the metal reducing resin only in one 10” cartridge, it helped so very interested in your result.

[@DavesKoiPond]

Thanks, 🙂
Sodium bicarbonate causes lot of elements to precipitate out of solution.
It's one reason why you can't mix calcium chloride and sodium bicarbonate solutions in dosing a reef tank,
But it only causes these issues if mixed together directly at high concentrations, once diluted in a reef tank the ions don't interact this way.
Did you speak to hanna instruments about any interactions between the reagent in their copper test kit, and any chemicals you also put in the pond?

@@DavesKoiPond yes the test only reads free copper and silver, cyanide can affect the results, nothing else should. At a loss where it is coming from in the last 3 days done 3 tests per day!!! And it’s range from 0.32 ppb to 681ppb!!!
Even thought of the copper in the food, but got no reading in a sample with food left in for 10 mins. Struggling to sort, so watching with interest on your metal reducing resin, then I could remove copper completely from my purified tap which runs around 48-50ppb of copper

@@DavesKoiPond also do you know if it could be the RO membranes, mine is working great, thought if they clean 1 minute every hour they are ok and get rid of the rubbish. Clutching at straws I think 😂

[@DavesKoiPond]

@@garychallinor6404 Honestly mate,
Best advise I could give is, if I was getting such wildly differing readings and my fish were suffering.
I'd go to a good dealer and get some professional help. 👍

[@garychallinor6404]

@@DavesKoiPond I’m asking around continually to fined anyone who can help, my fish aren’t suffering, a little extra mucous, but other than that all good parameters are all good, I’ve scraped and had them scraped and found nothing.
Just feel it can be better, investigating heavy metals etc is difficult and hard to test.

Great info bud great idea 💡 👍

You can get Hanna pocket checkers for certain metals. Personally I wouldn't make assumptions before adding something to resolve an invisible problem

[@DavesKoiPond]

Thanks, 👍
To be fair the hanna metal checkers are not very accurate at the very low levels that are toxic for koi.
I've tried the copper checker and it shows nothing, yet my severn trent tapwater area report shows copper at 37ppb...and nickle at 15ppb
I think the fish are the best indicator for problems in the pond, when I first added bonechar to my dechlorinator set up, I saw an improvement.
Also dosing metal chleating agents in tap water conditioner made another substantial improvement to behaviour and skin quality.
My tap water is horrendous for everything 0.8ppm chlorine, high GH, KH, and nitrate.
There are abundant metals in nearly all UK supplies, even if you live in wales and get fresh mountain water lol! 😄
One of the reasons bonechar has gained a lot of users over the last few years.
That was why I trialled the metal removing resin, that i sold by purity on tap for koi ponds, but it didn't work for me.
But as it removes hardness as well, I may have upset another parameter.... 🙂

[@modelshowblog-sj4rq]

@@DavesKoiPond I did not know about the unreliability of the Hanna metal checkers. Thank you for the information. If you knew the results of the trent tap water report, then the issue was not invisible and your actions were along the right line. Although I would say 0.8ppm chlorine is quite good. A lot of places in Europe take it to 2 or even 5ppm. Here it is 1.7ppm which I would consider reasonable. And yes of course - the fish themselves are the biggest indicator of an issue but the problem is many many things can cause the fish to present with something as being wrong in similar ways to very different problems that require very different solutions. You are likely more knowledgeable and experienced than most which reflect your thoughts and actions

[@DavesKoiPond]

@@modelshowblog-sj4rq Thanks, 👍
I've not found all hanna checkers to be unreliable,
I regularly use the hanna ulr total chlorine, and lr ammonia checkers and found them to be very accurate. 🙂
1.7ppm chlorine would be very high for the UK,
I know the WHO set 5ppm as a max, but all UK areas aim to stay below 1ppm with a lot below .3ppm
I wish we had the netherlands water quality with 0ppm of chlorine 😊

[@iainbusbridge9585]

I would have thought that if you are running RO that would remove everything including heavy metals.

[@DavesKoiPond]

Hi,
I'm running Recycle R.O. which will remove heavy metals from the pond water. 👍
But you still need to add dechlorinated tap water to replace what the Recycle R.O. puts down the drain to waste. 🙂
However in the next video it shows how my fish reacted badly to the resin...
