We noticed this weekend that all of our tanks have very high nitrates, 40-80ppm. So of course we tested the tap, 20ppm. We live in a small town and on Feb 19th they switched wells. Clearly the current well has a problem. (And yes, we'll be calling the town today.)
I use EI dosing so I can guess one of two things has happened. Today is Monday and I do a 50% change on Saturdays.
So the question is now, what to do? My best guess is to:
The good news is that the fish don't seem to be suffering and we also expect this to be a short term condition.
Oh, and of course Ammonia and Nitrites are zero, these are all mature, planted tanks.
Thanks!

- The water out of the tap was much higher than 20ppm
- My EI dosing has boosted the nitrates.
So the question is now, what to do? My best guess is to:
- Daily 50% changes until the ppm reaches tap
- Stop the macro dosing
