My aquarium is an experimental system. I am sure there will be setbacks.
So far my fish is doing fine and the 100 reading in NO3 could be
questionable because I see no signs of stress or excessive algae growth.
I use Salifert NO3 kit and Hagen, although I trust Salifert more, the Hagen
is giving me 50.
See, the whole purpose of the system is to test a new filtering system that
reduces the need to change water considerably.
I'll keep this forum informed!

Oh! but I will do water changes eventually, not yet!

Keep in mind that, if you wait until there are significant problems, you
will have to take really drastic action. With nitrates at 100mg/L, a 25%
change will only bring them down to 75mg/L. An additional 25% change will
only get them to 56ml/L.

If your fish begin to show signs of distress due to nitrates, you will
have to rapidly reduce the level to below 40mg/L, which will be a *very*
large water change.
