To celebrate 50 years of providing synthetic sea salt to aquariums and hobbyists Instant Ocean released a limited edition 50th anniversary commemorative 2.5 gallon jug kit. These handy kits include enough salt to make 25 gallons and are a perfect solution for your nano or pico tank at home or at the office.
Just fill the 2.5 gallon jug with RO water and pour in the premeasured package of salt and shake. Each kit comes with 10 individually sealed packages of salt. Once you use up your kit, the jug can be reused and it might be a good idea to measure or weigh a package before you use it so you can make your own refill packs in a ziplock bag. Hurry to get yours since these will only we available for a limited time.
