That is why it is important that the results are expressed correctly. That is the same as 11.3 mg/l nitrate nitrogen If it makes you feel better.

OK Just heard back. The council test came back at 42ppm +5 This is actually in line with my test as I probably read the red colour a little higher than I should have - is hard to tell the difference. Anyhow it is still unacceptable in my book. Apparently the NZ 'acceptable' level has crept up to 50ppm, something I find hard to believe and completely utterly unacceptable.
-
It will be a good thing to see the results that their tests come up with and compare that with the results that you are getting.
-
Not to the scientist doing the analysis
-
Any scientific papers I have seen express the results in mg/l nitrate (mav 50 mg/l) or mg/l nitrate nitrogen (mav 11.3mg/l). MAV stands for maximum allowable value. ppm is not correct as it is referring to both weight and volume as the same units.
-
You need to be careful how you measure and express your findings. PPM is not a scientific term.

As Alan said kick your water suppliers butt You could get the water tested from your RO system to see what it is lacking It will be soft probably and something like a commercial buffer may be an easy fix http://www.hollywoodfishfarm.co.nz/product/seachem-equilibrium-300g-5/

I know it does - by a long shot. The council came out and did their own tests - waiting for the results, as they don't believe my test results - who knows, I find it unbelievable too. They say their last test came in at 9.6ppm. They say that 10ppm is safe however I know from research I have read that in actual fact anything over .87ppm puts us at risk of colorectal cancer. It is very scary and stressful and to say I am angry is a gross understatement. The only reason I discovered this is because I could not get my tank nitrates below 40ppm despite heavy planting. Finally, not even suspecting this would be the cause, I tested the tap water and nearly had a fit. In the mean time I need to know about this RO filtration and what I will have to add to it to make it safe for plants and fish!
-
That exceeds the NZ Drinking water standard for nitrate and you should talk to your drinking water supplier and see what they are going to do about it.

Hi there, due to the ridiculously scary high nitrate readings in our tap water here in canterbury (80ppm!!!) we are installing an RO system. I understand thi strips the water of every mineral and I also understand that there are certain minerals the fish will need. So my question is what products do I need to get to restore the correct minerals/chemistry to the water. It is a heavily planted tropical freshwater tank. (see pic) Thanks in advance...I hope someone sees this 😉 Cheers

I purchased a second hand tank over the weekend and it came with fish. I have kept tropical fish before but not for about 5 years. I am in no way an expert and I like to research my fish well. The tank I have purchased has a real mish-mash of fish, some of which I have never kept before. I have 3 flying fox fish in the tank. They are quite aggressive and all research that I have done suggests that this is common, especially as they get older. I am moving them on but I know they are great at eating algae, particularly the black fluffy algae that other fish tend to leave alone. Is there any other species of fish that will eat this algae and is suitable for a community tank set up?

Hi everyone, I am new on here. It has been a few years since I kept tropical fish and I just got a new set up yesterday. My name is Shannon and I live in Hamilton with my husband and our 2 year old son.

Hey Killi keepers The latest import bought in eggersi and rachovii Some nothos that havent been in nz for a few years now If anyone knows of or heard of anyone who has a spare eggersi male please let me know We have 3 female eggersi and our last male now appears to have dropsy with his swim bladder issues. We have a comfy 2 trios of rachovii and 2 more females arriving this coming week. We also have palmqvisti and korthasae we look forward to sharing eggs with other killi keepers

Sadly you have done the best that you can, sometimes they recover. Possibly dropsy or gut infection.

My honey Gourami laying flat on her side for the past 2 days, been worse on the second day. I have hospitalised her, raised temp to 30 deg and treated with methylene blue and gave her peas, she's not eating, but gills or moving. Occasionally she tries to swim but falls back down to gravel. She also has slightly enlarged rear side compared to rest of the body. Anything better I could do to save her?
