Many thanks for the tips your help is appreciated
Mike has a good link there.
How old are your test kits, are they liquid or strips?
Can you get your LFS to doublecheck your nitrAtes and phosphates?
Is the tank in front of a window?
What/how much/how often are you feeding?
Age is relative, you are only as old as you act....of course, this works in reverse....
The test kits are 6 weeks old and all are liquid, the tank is in a alcove with no direct light on it, frozen brine shrimp 2 shakes of the frozen cube aday just so a few shrimp come off as directed by lfs. And just a couple of flakes of New Era Marine Flakes for the shrimps
