Less than a day old.

Sorry, I confused electronegative charge with negative charge. NO3 doesn't have an electronegative charge. It just has a negative charge of -1. (stupid meds...) I've read that people usually use sodium chloride to regenerate mixed bead resin, but that will add sodium choride back to the treated...

Here is video showing how to regenerate and seperate mixed bead resin with hydrochloric acid and sodium hydroxide. There is a product called Nitra-Zorb which I assume is a anionic ion exchange resin and some kind of zeolite. They advise customers to recharge it with sodium chloride. Mixed...

Thanks BillTre, My current aquarium set-up oxidises NH4 rapidly. I don't want to add sodium or sulphate as my fish are from the Amazon and prefer soft water. I would imagine hydroysis would occur faster if I added my portable air pump to the garden vat, but I was just trying to gauge how long...

My tap water has chloramine in it, so it's not safe for my aquarium. I fill a large vat with tap water in the garden and add a few pinches of ascorbic acid to break the chloramine into chlorine and ammonia. I add the vitamin C first and then fill the vat with a garden hose. How long will the...

Also, there is 60mg of phosphoric acid in a can of Cola-Cola. One drop of liquid is 0.05ml which is 50mg. My phosphoric acid is 45%, so I figure I can add 2 drops to a 330ml drink to safely give it some extra bite.

Thanks, I made a mistake with my rough calculation. I should have estimated 0.72ml, not 7.2ml. 0.67ml is more accurate. I was adding slowly and testing each day. I got to 1ppm quickly, so knew my math was off.

Thanks, I calculate that at about 7.2ml of 45% phosphoric acid to raise PO4 by 1ppm in 300 litres.

How much 45% phosphoric acid (in ml) would it take to raise PO4 by 1ppm in 1 litre of water? I need to be sure as fish are involved. It will be administered over a 24 hour period.

https://www.mankysanke.co.uk/html/anoxic_filtration.html This paragraph in the article confuses me, 'Beneficial filter bacteria will be as busy as ever converting ammonia to nitrate in the aerobic areas of the biological filter, but bugs that can live in anaerobic conditions will rapidly...

Thanks, it was the Translator app that was at fault (Chinese to English). I tried translating with the phone camera again and active ingredients translates as only potassium dihydrogen phosphate 98% now.

I have a high PO4 demand in my aquarium due to carbon dosing. Why does the packaging state 98% potassium dihydrogen phosphate and 98% potassium dichlorophosphate? Why is potassium oxide and phosphorus pentaoxide mentioned with percentages?

Thanks, I'll just use it for my plants then. It was only a few pounds. This is written on the packaging. KH2PO4 98% Active ingredient: potassium dichlorophosphate 98% potassium oxide 33.8% phosphorus pentaoxide 51% From what I've read, phosphorodichloridate would hydrolyse into hydrochloric...

I've ordered some on eBay from China to use in my aquarium. I'm not sure how it is make and wondered what the impurities would most likely be from the manufacturing process.
