Sorry, to be the bearer of bad news, but East Anglia Water are my suppliers and I get the same results. On the upside you don't need a new water test kit.

First question do you have an RO filter?

No, I don't have one. It's going to be quite difficult to 50-75% change a 140 gallon off RO water? Why are the UK allowing such high levels of nitrate? Does anyone know the UK law for this?

The UK is only following the minimum set by the EU in 1980. Based on this, it sounds like you can complain above 50ppm (mg/l) of nitrates in your drinking water.

Thank you, Rock! Didn't see that one.

I just went out and bought a Waterlife liquid test kit. This one reads 25-30ppm. Not sure what to believe now, but it sounds more believable than 160ppm.

Ive been keeping an Oscar in this water from East Anglican Water for over two years.

There are ocaisional nitrate spikes throughout the year. There was a major spike a few weeks ago. You might have not read it correctly but API test kit was correct. There are tests on the below thread to prove it.

www.oscarfishlover.com/forum/37-write-a-review/303426-nitrate-filter-deltec-nfp-509?start=20#380173

I just tested My RO water at 0ppm tap water is currently at about 40ppm,

Even at 25-30ppm you are going to have difficulties. Oscar tank water needs to be around 20ppm or lower. You cannot acheive that with tap water at 25ppm.

Yes it is illegal for the water to go above 50ppm; except for when adverse enviromental conditions push it over the limit, such as drought or flooding. It is perfectly acceptable by law for this to happen a few times a year. Unfortunatly it happens more often in this area and when it does happen it really goes for it.

Thank you for the honest advice. So my options are pretty much -
Give up keeping Oscar fish and rehome
Obtain RO equipment >> ASAP <<, which could be difficult as I'm in the process of moving home.

How do you transfer from your barrels into the aquarium? Obviously the changes on my 140 gal are going to be difficult, and I'd have to keep the barrels in the garage. Is it just the RO unit I'd need? Could I adapt my python with some sort of pump from the barrels?

Thanks

any sump pump or even power head will work, just connecte vinyl tubing

Your talking about pumping water from the barrels right? Not converting a normal filter into an RO filter, which is what I thought he meant.

Not sure what you mean by python. Im assumeing you mean your current bio filter?

No you can't modify an bio filter to work as an RO filter. RO requires at a much higher preassure, you need an RO pump to achieve this. The preassure forces water through a RO membraine which mechanically splits the water. This means for every 1 liter of RO water there is approximatly 3 Liters of waste water.

The reverse osmosis process stripes out all metals, chlorine, minerals everything. The upside of this is that you don't need to use water conditioners.

The down side is that it has no nutrients/minerals which can have adverse affects on your fish's growth.

Alot of people will suggest mixing RO water with Tap water to get the minerals and nutrients back. This is fine, unless your tap water goes up to 80ppm. If you are going to use tap water, you still need to use conditioner on the tap water.

I have two 25 litre barrels with a tap on the top, picked them up from Pecks in Ely if you know the place. I will fill the barrel and leave it over night in the kitchen or near a radiator to get up to temprature; even if you do this the water will likley be colder than the tank.

I lift the barrels above the tank rest them on a ladder then use a piece of PVC pipe and 90 bend on it to direct the water into the tank.

If you don't have the time to get it up to temprature, just clkose the tap a bit further on the barrel and reduce the flow into the tank.

Alternativley you can avoid useing barrels all together. This is my preferred method. I just use a long pipe from the RO and it pours directly into the tank because it pours at a relativley slow rate you don't need to worry about temprature.

You can then pour your tap water into the tank, just make sure you have your ratios right before you do this. i.e. if you want to put a final mix of 20ppm max use 50% RO water and 50% tap water at 40ppm.

In the case that your tap water has to much nitrates and you cannot mix the water you can use RO water on its own; providing you dose with trace elements. Seachem sell a specialist trace elements for Cichlids.

As your fish get bigger the battle with nitrates will intensify. I was seriously considering giving up my fish earlier this year. This was because the nitrates in the tap water was so High my RO filter didn't manage to remove all of it. I took it for granted that my fIlter would remove all nitrates and ended up doing a water change with about 20ppm water. I can back from my christmas hols in Wales and found my Fish were showing early signs of HITH.

Yeah, the "final" water stored in the barrels can just be pumped into the tank if you don't want to use a bucket.

The python is a water changer hose, basically consisting of a vinyl tubing and male and female connectors that will allow it to connect to a faucet.

Oh yeah seen those things.

Nothing wrong with an ole bucket and a bit of elbow grease.
