How high a PPM is counted as high NO3?

[mingwen1611]

Hi all...

as of the above... i would like to find out how high a PPM is counted as high NO3? is 100PPM too high? what to do if too high? change water?

Unless you test kit gave incorrect result, else you inverts are in high risk. Though, many reefers maintain at ZERO level, I could only achieve 10ppm, which is still ok for my livestock.

Good luck

ok.... thanks for the reply... but how to make the nitrate level drop? will water change help?

Ya... Water Change will reduce NO3...

[mingwen1611]

ok... will do..... gonna do a water change...... for all the replies and advices...

For optimum results and if you have a small tank, you may wanna use distilled water to mix salt with.... coz tapwater can contain high levels of no3 too... try testing your tapwater at home... but if you tank is 3 feet, you may have to spend quite a bomb on the distilled water... for 2 feet, should be pretty okay...

It cheaper to get a DI unit for the long run. It'll take quite a while before you need to recharge the resins if you have a small tank. It'll also get rid of PO3 for you. Beats using those expensive phosphate removers regularly.

Michael,

care to explain more about the DI? I'm keen to know...

Here's my 2 cents worth:

A DI unit contains cation or anion resins (or both, I'm not too sure) that will react with the water to purify it. A RO unit usually produces water that is about 95% pure but the DI give you pure H2O (0 Nitrate, 0 Phosphate). And you also fill up your tank much faster than using a RO unit.

The only set back is you need to either replace these resins or have it recharge after sometime by some shops that specializes in water filtration.

You would increase the life span of your DI resin if you hook up a prefilter and a carbon canister before the DI unit.

sorry, in case i got it wrong, does DI refer to de-ioniser? is there one for marine tanks?

water change is not a long term solution and also not cost effective. Try DSB, it take a while to function but once it kicks in, no more NO3 problem.
