Hello everyone. I am recently retired and am in the process of starting up a new saltwater Coralife Biocube 14 in an effort to familiarize myself with saltwater aquariums. I have setup and successfully maintained numerous freshwater tanks over the last 45 years and now that I am retired it is time to try saltwater. I decided to start with a 14 gallon Biocube while I am in the process of renovating an upstairs room in my house where I hope to ultimately setup a much larger saltwater tank if I am successful with the Biocube 14. Currently the Biocube has been running for a week with three live rocks and live sand. One of the live rocks has quite a few invertebrates growing on it which appear to be Mushroom Anemones (not sure). The water is crystal clear, the Anemones are thriving and the salinity is just right but I have not yet performed any other test. I have ordered test kits for ammonia, nitrites, PH and alkalinity.
Now for a newbie question. I purchased three gallons of RO
water for topping off from a LFS
. I have it in a 5 gallon potable water container that is sealed. Does this RO
water have a shelf life? The LFS
said that I need to discard it after a couple of weeks. That surprised me. I assumed that if it was held in a proper sealed container, that it would be usable for a lot longer than two weeks. Thanks in advance for any help.
