What test kits are recommended to have on hand for every serious planted tank keeper?
I'm fairly sure my Red Sea Fresh test kit may have expired reagents and probably wasn't that great to start. What brands for each kit would be best?
Here is a list of items I thought of:
pH test, KH test, GH test, Nitrite, Nitrate, Ammonia, PAR meter
Other recommended equipment and brands? I have a pH probe, but would like a test to verify my calibration of it.
Thanks for the help.
