Worldwide Imports AWW84130 Live Nutri Seawater, 4.4-Gallon

I have purchased this water a total of 18 times so far. It is really nice to have one on hand to use when life gets in the way of making saltwater and doing water changes. After testing parameters of this water everything seems in order. My tank is on the smaller side so its the perfect amount for me. The fish seem happy and I do notice the corals perk up a bit. I am not sure if its the water change or this stuff. I probably use this water about every 4-5 water changes due to my schedule. I try to order them when the price drops just to have one hand. Saving the jug and using it when you are siphoning or vacuuming is nice too. You know that the refill will be inline with what you took out. The small hole keeps the sand vac's tube better then a bucket too!Now I will say about 1/3 of the orders of this water arrived damaged or leaked and were returned by UPS or USPS. Amazon replaced every one of them. So just plan your order times accordingly. There is a good chance it will take a couple extra days due to a replacement.

Fish are healthy

I love using this water, very easy and always makes water changes quicker. The tank is healthy and happy and crystal clear. My only gripe is, The packaging needs to be upgraded. The seal is always loose and 2 out of the last 4 had to be returned due to damage. I'm on auto-ship and rely on these. They need to do a better job of packing and shipping through Amazon

This is great for smaller home aquariums of 150gal or more. I say 150 gal or more because of the cost effectiveness If you have been at the SWT hobby for any amount of time you know that nothing is cheap. When you add up the costs for the RO/DI units, Replacement filters, Replacement RO Units, New DI media, CO2 for coral and coralline algae growth, UV Filters, Charcoal media, additives, and then if you really want to add on to it the cost of the salt to make the water and the pump to pump it in to the tank, the time and the effort it is just beyond enormous.You buy all this stuff and then do a water change and in the end the same 4.4 gallons that you buy here premade and ready to go and enriched would cost you 50cents to 1 dollar more to make per gallon on your own.This has revitalized my tank and all my leathers, corals, fish all are happier and the colors have just bloomed!!!.Do yourself a favor and get it. It is so much easier then guessing all the time.

Product itself is great but 2 months of deliveries and 2 broken seals, crushed boxes and no idea if it is safe. I feel like i'm getting the bottom of the barrel.

One of the jugs caps and seal was broken making the water unusable.

This water is probably keeping my impulsive buy of a blood red fire shrimp alive on a one month and 2 week old 10g nano started with this water and I now use it for every water change. My coralline algae is doing good however that a mix of the coralline spores and the purple up I been adding now and again. The salinity floats between 1.025-1.027 which is not an issue since a .001 increase to your salinity will not stress anything, if need be a little RO/DI water or distilled can be used to lower it however I would advise buying a water heater to heat the water something in a 100w range is the salinity reading will depend on temperature to be accurate.

I have used this for years and my fish are as healthy as can be, one of them is 11 years old! It's pricy if you have a large tank or if you have a new tank and need to do extremely frequent water changes. My tank is 30 gallons and well established (over a decade), so for me this is still economical. Highly recommended for easy routine water changes. Not only a time saver, but my fish seem to love living in it.
