mixing halogens?

[Eyore]

what would happen if I were to mix- bromide, fluoride, and iodide together in ro? any issue with adding boric acid as well?
(in a proportional way (so much more bromide than the others)

potassium and /or sodium for the cation?

any possible reaction with adding to bicarbonates? chlorides (halogen)? sulphate?

 

[Randy Holmes-Farley]

Those are all fine, although, the iodide (which presumably is low in concentration) may be oxidized over time to iodate (IO3-).

 

[Eyore]

less than 0.1%

would the iodate have the capacity to turn back to iodide in the water? would it even need to?

so to reiterate, I could combine with mgso4 and mgcl as easily as nahco3? no issue


again, thanks for your help

Hi,

How did you establish that you need these halogens?

Cheers

hi bulent

guess you were right afterall lol

lets say I am looking towards the possability of a home brew

wether iodine is to offset dilution only or also dose, I havent established in my desire

 

[Randy Holmes-Farley]

Yes, you can mix these halogens with either MgCl2/MgSO4 or an alkalinity additive.

I don't think iodate is well taken up, and when I experimented with dosing it, it accumulated, which I- definitely does not do.

I discuss it here:

[Dami]

any issue with adding boric acid as well?

Anything in particular besides it being a toxic chemical, banned in the home and harmful to humans..?

Anything in particular besides it being a toxic chemical, banned in the home and harmful to humans..?

the ld50 for rats is comparable to sodium chloride for borax, a bit lower for boric acid, I guess because its of a greater weight of boron.

dont know if its banned but I seem to be able to get hold of both quite easily- I stopped short of paying

 

[Randy Holmes-Farley]

Sodium tetraborate (what you'd use) is sold in grocery stores in the US as 20 Mule Team Borax for laundry cleaning.

 

[Eyore]

Sodium tetraborate (what you'd use) is sold in grocery stores in the US as 20 Mule Team Borax for laundry cleaning.

why would I use sodium tetraborate over boric acid?

out of interest why do both these have danger plastered on the packaging?? if its toxicity is comparable to table salt?? is it as simple as health and safety gone mad!? (though maybe things are differant in the states, in the uk we have to contend with the eu)

thanks for the help

 

[Randy Holmes-Farley]

Because it is cheap and easy to buy. I think boric acid might be used to kill cockroaches.

Long term low exposures to things can be toxic without killing, but I wouldn't overly worry about sodium tetraborate relative to other toxic things you are potentially using (fluoride, for example). Just don't eat or breathe any of them.

 

[johnike]

That is correct Randy, Boric Acid is a great home insect killer.

my research over here shows both are available at a similar price, both appear to insecticides, but boric acid appears more common for this. tbh having just totted up the figures boric acid is approx 50% stronger than sodium tetra borate in terms of boron, so makes little odds regardless in these amounts

the fluorides, yes I must admit! a little scary

however (feel free to correct if this is wayward! ) the ld 50 on potassium or sodium fluoride is around 1/10th that of sodium or potassium chloride, and lets face it in this hobby I play around with 100s of kilos of that every year! and then how much do I poor onto my chips (fries I guess to translate)!! (not of good stuff btw)
so lets face it, I am far more likely to inhale or ingest these than potassium fluoride

 

[Randy Holmes-Farley]

If they are both available, use either one you want.

Boric acid kills the roaches & fleas, but what does it do to your man-hood?

Abstract

The aim of this study was to investigate the consequences of exposure to three levels of boric acid (BA) on male rats reproduction, fertility and progeny outcome, with emphasis on testicular DNA level and quality. Adult male rats (12 weeks old) were treated orally with 125, 250 and 500 mg/kg bwt/d of BA for 60 d. The results indicated that BA administration at 125 mg/kg bwt had no adverse effects on fertility, sperm characteristics or prenatal development of the impregnated females. However, at dose 250 mg, BA treatment significantly increased serum nitric oxide, testosterone, estradiol levels and testicular boron and calcium levels and also significantly reduced serum arginase activity, sperm quality and testicular DNA content with minor DNA fragmentation. The impact of BA exposure at dose 250 mg on male rats fertility was translated into increases in pre-implantation loss with a resulting decrease in the number of live fetuses/litter. In addition to the significant alteration of biochemical measurements, observed at dose 250 mg, administration of BA at 500 mg caused testicular atrophy, severe damage of spermatogenesis, spermiation failure and significant reduction of Mg and Zn testicular levels. None of the male rats, treated with 500 mg/kg bwt, could impregnate untreated females, suggesting the occurrence of definitive loss of fertility. In conclusion, BA impaired fertility, in a dose-dependant manner, by targeting the highly proliferative cells, the germ cells, through decreasing DNA synthetic rate rather than the induction of DNA damage.

I wouldn't spread boric acid around your house like some do, some cover their carpets with it!

I wouldn't spread boric acid around your house like some do, some cover their carpets with it!

Meh, I was fixed decades ago.


I use it around the perimeter of the house, I live in a heavily timbered area and it works wonders.

 

[Jay Ellul]

Sorry to hijack - q aimed at Randy...

I am needing to start dosing Potassium. is there a calcium uptake to potassium uptake ratio and can i just mix this into one of my randy's recipe supplements???

 

[Randy Holmes-Farley]

No, definitely no fixed ratio.

Potassium is not depleted by the same processes. Potassium is important because it is generally kept reasonably high and at a steady concentration inside of cells of most organisms.

If it is being depleted in a reef system (it isn't in all systems), then that is because you are somehow growing more tissue with more potassium in it than you are adding back in foods and other additions. There is no reason, a priori, to think it will deplete since the additions may balance the uptake/export.

But, if for some reason input is inadequate, then potassium can become depleted and may be worth monitoring and supplementing. A number of folks seem to fgind this beneficial.

FWIW, my system, with ~1% daily water changes using normal IO, has not become depleted in potassium and I never supplement it.

So before thinking of supplementing, I'd look to measure it somehow and determine if you have a need.

I dont need to plant any more seedlings tbh, providing I have the ability to practice I am happy enough!

thanks for the help randy

 

[Jay Ellul]

mixing halogens?

I have measured. Have lost 60ppm over a couple of months. So manual dosing will be quite easy

Was just asking as if there was a ratio is just add some K to my next batch of alk or Ca.
