got 4 gallons of this today.. pretty good prices, even better if the pool grade h2o2 they sell is usable. i tried emailing with no response, im not sure what the differance could be.
just answered my own question on their site.
Contents:
The hydrogen peroxide of our pool and spa packs are IDENTICAL to G.O.E. 35% food grade hydrogen peroxide - the premium source of food grade hydrogen peroxide for internal health usage as a health supplement. G.O.E. prohibits selling any 35% food grade hydrogen peroxide as "food grade" under their name that is more than 30 days old from sealing.
For pool and spa 35% hydrogen peroxide, G.O.E. does not guarantee the contents are less than 30 days old and will allow up to 90 days for gallons stating their usage is for pools and spas. However, it is labeled "Pool and Spa" rather than "Food Grade" for the distinction. Pool and Spa 35% hydrogen peroxide is 100% suitable for any other usage of food grade hydrogen peroxide. Its concentration level at 90 days will be 34.4 to 34.1% and has exactly the same level of purity.
H2o2 never "spoils" or goes bad. However, over time it does "decompose", which means releasing the extra oxygen molecule of its h2o2 composition.
While it can vary depending upon temperature of storage and whether exposed to U.V. light, if properly stored h2o2 will decompose at a rate of 1/4 to 1/2% concentration level per month. As concentration gradually reduces, its rate of decomposition slows.
Pool and Spa 35% hydrogen peroxide is NOT outdated G.O.E. h2o2 food grade hydrogen peroxide that has been relabeled. No bottles are allowed to be changed. Generally it will be as fresh and less than 30 days from sealing. But we are allowed to offer it for sale up to 90 days from being sealed. G.O.E. is very exact on quality standards. The result is unmatched quality, purity and potency at a notably reduced price.
