Coral Chips and Nitrates, In Sump Tank, NO3 Options

[GoldfisHub]

Hi Guys,

I am in the mist of setting a goldfish tank, for the sump tank, I intend to place lots of coral chips so that I can achieve the effect as in the marine tank and hopefully that can get rid of NO3. However, with lots of coral chips, will it affect the water condition and hence affect the grooming of goldfish, like pH, Calcium not sure what else. Anyone has any experience or thoughts to share?

Hi everyone,

I need some advise from bros here with regards to the above-mentioned:

PH : 5.5
Ammonia : 0
Nitrite : 0
Nitrate : 50 mg/l

Have been having this problem for 2 weeks liao, still cannot resolve low ph and high nitrates problem. Nitrates can go up as high as 100 mg/l in a week. My current setup is a 500 litre tub (outdoor) serviced by 2 cannister filters loaded with biohome only and a 13w UVC. In the tub are 9 ryukins and 1 tosakin. Pls. advise how can i up the ph and reduce the nitrate build-up. Water change is about 50% a week. Thank you in advance.

Remove all the material from one of your canister and totally fill it up with coral chips, nothing else. Run it for 1 week (without water change) and measure your pH and NO3. You will be getting surprise results. )
