I work in the municipal water field and if you live in the United States and your tap water has 10 ppm or more then read this:

www.epa.gov/OGWDW/contaminants/dw_contamfs/nitrates.html

10 ppm is the MCL (Maximum Contaminant Level) allowed in tap water. If you have more or are close I suggest calling your local supply and letting them know what you found.

As far as ammonia goes, some places use chloramines as a primary or secondary disinfectant which is created with a combination of chlorine and ammonia. It is better for disinfection and stays in the water a little longer than chlorine but it is worse for fish. So it may be normal to have some residual ammonia in your tap water.

Would a simple tap adapted purification device remove nitrates as ive tested my tap water and the readings are only about 20ppm but would like nil, dont want to use Ro as to much waste.

I have been fighting Nitrates as well. I found that my tap water has ammonia in it. As we know that shortly breaks down into nitrates and nitrites. I had no idea there could be ammonia in my tap water. I use an under the sink filter for that sink. Maybe time to change it??


I would'nt be drinking any of that tap water will make you sick.

Well it may not make him sick at this point, his body has probably formed an immunity to the water by now, however for the fish not so great. Rain water, however rain water can contain contaminants, and the labor of retrieving the rain water and it's scarcity make it hardly worth it. I am sure there are water purification systems to handle this dilemma, but at what expense?

Hoping not to high but going to find out about simple additions to the tap and how much of what contaminents it removes.

So I have 30-40 ppm nitrates coming out of my tap, as a result Ive a planted tank and bamboo and I'm currently looking into additives.

Anyway my first majour water change will be a 90 - 95% at the end of the cycle. The tank is 560 ltrs if it was brimmed (lets call it 500) I will be refilling the tank with 50% bought water. It will cost me £21.25; I have done this to make it easier for the fish to settle.

My question is, with a tank of this size keeping one Oscar how much and how often should I do water changes. Since the tank is 125 us gal for one fish I'm hopeing a weekly 10% should keep the nitrates at bay. If I was to use bought water this would cost £204 per annum.

Does anyone know how quickly the nitrates will build up in a tank this size with one fish? Could I even do a 5% water change per week?

Or should I just fork out one of those RO machines, from what ive read they are simmilar cost if you take into account replacement cartidges?

we had to put in an R/O syastem - not for nitrites but for phosphates...we are in a farming area up her and the stuff leaches into the water supply.

actually it's been better lately, but we also chlorinate and fluoridate over here in the UK and I wanted as much muck out of the water as possible....so in went the R/O system...it's not as expensive as you think - the R/O right water conditioner lets you determine the parameters of the water as well (tip - bite the bullet and buy in bulk then STORE IN A VERY DRY PLACE this drops the cost dramatically.


and it's certainly a cheaper option than paying for water at £204 per annum.

I bought an RO unit a few days after that post. The unit I required was £100 and wastes 2/3 water each change, but my nitrates are staying around 10-20ppm with a maximun of 5% water change every week and a 10% once every month.

I suspect useing RO water is more expensive by the time you take the cost of the unit itself, replacement filters and the amount of waste water. However it is far more convienient than collecting loads of water per week. I also found the bought water increases in nitrates in just a few days without any ammonia. I suspect the water has something in it which assists/accelerates the cycle.

well, i dont want to read for 3 hours to get the entire picture
but my tap water has about 20PPM of nitrate as well.
i found a product online from a Canadian only store. you can probubly get the same product elsewhere, just not by this company or store =/
but worth a shot to show people.
