What's on your mind Henny?

i dont use ager for my water in torbay, but new to massey, so making sure someone is also using tap water with no ager

my drum eventually will have a aerator as i usually do.

just to aerate it but making sure that straight tap water in water changes is ok:D

I guess you would get water from Waitakere reservoirs?

I recently downloaded water quality reports from them and also spoke to them and the conclusion is that this water is very good quality rainwater with relatively little TDS or anything else for that matter.

They only add a bit of calcium to help stabilise pH at 7.5 I think and then of course the usual chlorine (not much) and fluoride.

yeah, i have put the water in alreayd but i have been making small 10 to 15% water changes.

but just checking.

NZ water is generally good.

i have oyster shell in the filter to add some buffering capacity. my ph is quite stable with this method and regularly calibrate the ph meter.

good to know though, thanks!

we are still waiting for your pics of the wild discus in the show tank:D

When you add chlorine to water you get hypochlorous acid which reacts with nitrogen compounds like ammonia,urea and the amines (in all proteins) and forms monochloramine. When you add more chlorine you get dichloramine and even more you get trichloramine. All these (and other reactions) form part of the "chlorine demand" in the water. You cannot get free available chlorine until this "chlorine demand" is satisfied. Therefore when the reaction is pushed towards trichloramine there will be virtually no monochloramine present. In some states in the US they treat the water with monochloramine (made by reacting chlorine with ammonia) because chlorine will react with other impurities in the water and form some compounds that are not so nice (such as acetone) where as monochloramine will not. Monochloramine is not as effective in treating water as chlorine which is used in NZ but is still a strong oxidising agent.

When people complain that the chlorine in a swimming pool is too strong and it is burning their eyes the problem usually is that the free available chlorine has been used up by contaminants in the water (such as urea) and this has pushed the chloramines back towards the monochloramine and this is what is burning their eyes. The problem is fixed by adding more chlorine.

When you allow water to stand or aerate it to get rid of the chlorine the chloramines all move back to monochloramine and this will react with your fish the same as an under chlorinated swimming pool will with your eyes.

Chlorine and all chloramines can be converted to more harmless chemicals with the addition of sodium thiosulphate which is the active ingredient you are buying from the petshop with dechlorinating products.

Drinking water will contain various impurites that add to the chlorine demand and will form chloramines and other compounds. Ammonia is a bi product of the reaction when adding thiosulphate to chlorinated water. Chlorine only is used to sanitize water supplies in NZ and when you add chlorine you will always get chloramines unless you use distilled water.

To summarise. Correct me if I am wrong.

Chlorine reaction g to stuff to sanitise will always produce chloramines

We add chlorine to our water at the plant

Chloramines cannot be removed by aerating

In a nutshell... You say one should always use a product like prime or similar?

If you have chlorine in the water you will also have chloramines. The answer is yes. When you use dechlorinaters they are usually sodium thiosulphate and it reacts with chlorine to give coloidal sulphur, hydrochloric acid and sodium sulphate. I don't know which of these is toxic to invertibrates. It further reacts with chloramines and one of the biproducts of that is ammonia which I think prime will handle, possibly by converting to ammonium.

Could be a worth while investment getting a 2-10K litre tank to catch the rainwater off your garage roof?

was looking into that.

the extra water for the tank will cost very little and return on investment is quite slow, I did look into it and is part of my 'to do list' eventually.

still haven't even insulated garage door haha

I will go with the greenstuff stuff, then seal it in or something.

also nowhere to put the water tank:D tight for space!
