nitrate problem
 
after doing a test recently in one of my tanks i found out the nitrate level was very high,a water change later revealed the same result...my tap water now has a high nitrate level ive gotten around this using a brand name nitrate remover ..how do i nutralise this water completely of its nitrates before using it? the product im using in tank is a small bag but this wouldnt be practical for treating tap water any suggestions??

How high or a reading are you getting from the tap? And what is your usual reading from the tank(s) whenever you do your tests?

The only way I know to remove nitrates and such from the tap water is to get a RO filter. This removed pretty much everything and leaves oyu with (ZERO) water or water that has no GH, KH, or anything else. Youw ould have to add these things back in but it would give you a lot more control.

ro units are out of my price range ....the normal reading is about
0-10ppm which i kept down with water changes the tap water is now reading about 10ppm so water changes double the nitrate level it does show that the water coming out of the tap is not as pure as it seems there must have been a switch in supply

10ppm is most certainly not high for nitrates at all. I wouldn't even start worrying about it until it got to around 50ppm!

My usual reading (for my planted tank) is around 5-10ppm but I'd expect a non-planted tank to have a higher nitrate reading.

thanks its a lesson in knowing whats in the tap water god knows what else is in there

I agree...my 29g freshwater stays right around 20ppm Nitrates with plastic plants.

You could possibly think about having some "Purified Water" on hand to add when a level of Nitrates become too high in one of your tanks.

Purified Water: This is a type of drinking water that has been treated with processes such as distillation, deionization or reverse osmosis. Basically, this just means that the bacteria and dissolved solids have been removed from the water by some process, making it "purified."

I agree, 10ppm is pretty low. I run with 20-80ppm in my tanks, though most of them are lower now (5-10 range) as my plants are starting to grow. Personally, I wouldn't really worry til it's over 160ppm. I have seen fish survive fine in tanks with this level of nitrates for prolonged periods of time with non adverse affects.

thanks i thoght it was a real problem :oops:

I try to keep mine between 20-40ppm just for the plants and to keep them growing as fast I want them to.

160 ppm is kinda high though leifthebunny, I have heard that any moderate exposure to levels over 80 ppm can be harmful or even fatal to fish. OF course this depends on what kinda terst you are suing as to what levels you could see no effects from to the fish. When I used the test strips it seemed like it always read above 80ppm with no problems. But with my liquid regent test kit I have seen problems at 60-80ppm.
