Glutaraldehyde/Metricide shelf life (1 year+ ??)
I just ordered a gallon of Metricide 14.
What does it mean by "Metricide 14 day"?
I've read up on this and it's about double the concentration of Flourish Excel.
Thus it should last me about a year. I'll need (maximum!) 10mL per day, so that's about 380 days worth of dosing.
Should I expect this stuff to remain useful for a year, once opened, stored at room temp?
Also, at normal dosing levels (2-3 mL per 50 gallons) will this have any harmful effects on Crystal Red shrimp or red cherry? One of my tanks has a BUNCH of them. The other has none.
Finally, should I expect this to kill my subwassertang like it does riccia?
