Gort! Klaatu barada nikto.
Sorry, but I largely disgree with what this site is saying. It rolls out old, tired, and unproven statements about nitrates such as:
"Readings above 50 ppm (Parts per million) need urgent attention and it is considered that a reading of 20 ppm or under is acceptable."
There is no evidence to suggest Nitrates >50ppm are harmful to fish, yet there is evidence of fish living in these levels for years.
It also suggests reducing nitrates and phosphates as means of removing algae, yet algae can be grown in RO water using just sunlight.
Once it has finished telling you to remove nitrates and phosphates, it then goes on to say you should add them via plant food.
It is also incorrect when it says that CO2 levels in excess of 20ppm can adversely affect fish. All my fish are kept in 30ppm with zero problems.
Like SJ2K says, you will just have to keep on top of the water changes to keep ammonia and nitrite down.
Dave.
