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.

For algae growth you need to have strong lights...

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!

How long will you debate over this 100mg/l nitrates
to finally conclude your test failed spectacularly ?
