I use hydroguard in all my res's, hitting mid 70's res temps in mid summer without an issue, but I run higher air volumes than most, which really helps.
Twistedwords is partially correct, res temps between 68 and 72F are ideal for home growing, it's where the water can hold enough DO support plant growth and be warm enough to not slow down biological process. Under 65F biological processes slow down, but DO greatly increases, over 72F biological process are ramped up but at depleted DO levels and risk of pathogens, res temps between 70-75F would be ideal if DO and patogens can be adequatly controlled. Most home growers don'the have the ability to maintain res temps in this range, and keep DO up and pathogens down, which is why lower/mid 60's is the generally accepted range. It keeps DO up in an environment which isn't conductive to pathogen growth. Get res temps around 72, get enough DO and keep a good bacteria culture going and you will see increased growth.
I had a open HG bottle for close to a year, i never saw any decline in effectiveness. I kept a HG culture going in a 10 gal tote for a few months off one dose. It's a living bacteria, so once you dose, if you keep giving it food it will continue to colonize. I just scooped out a cup or two and added it to my res's every few days, then added back ro, for food I'd throw in some old roots or leaves, any dead plant material. When the bottle I have gets low I'll start another culture, hopefully won't have to buy it again after that.
