how many boxes of the 4.4 gallon of nutri- seawater would i need to get to fill up a 20 gallon tank
Answer by Chewy • Dec 05, 2017
For routine water changes: It is recommended to change apportion of your aquarium water 10-20% of volume regularly with Nutri-SeaWater to restore your marine system to Nature’s Ocean. One jug should be enough for one water change for a 20 gallon tank.
What's the specific gravity of this pre-made saltwater? I wouldn't want a big change in salinity while doing the water changes. Thank you
Answer by Chewy • Dec 15, 2017
The specific gravity of this Saltwater is 1.027.
lt states that this water contains bacteria but how does it live without any food?
Answer by Chewy • Jan 25, 2018
Natural sea water does contain trace amounts of dissolved organics which sustain the bacteria.
What is the density of the Nutri-SeaWater?
Answer by Chewy • Jan 24, 2019
The density of the product is 1.027.

Works great and much easier than mixing your own

I just got my first saltwater aquarium set up a few months ago and used this water to cycle my tank. Even though box says ready to add fish, I still wanted to cycle my tank for a few weeks. I give a 4 star because the water is pricey but much easier than mixing your own water and having to use a heater to match water in your tank etc. Mixing your own water is more of a chore than anything else, and I definitely recommend the pre mix water instead, plus you'll save time this way.

Not worth it

Crazy overpriced for what is supposed to be actual ocean water. I was surprised when I tested it how low the salinity was, only registering 1.018 on a refractor meter. I suppose it will work if your just topping off your tank. It suggests to do a 15 to 20% water change before adding on the box. That would drop my salinity way to much of I only added this. Definitely not worth the money I was charged.

Usually good but...

This last shipment came in and one container was leaking and the water was green and the other 2 had no seal on them and looked as if the water had been replaced. Glad I figured it out before adding it to my tank but I’m pretty disappointed that I have 15 gallons of trash now and need to go to the store and spend more money to do my weekly water change.

Water change

I used this for a reset on my reef after slacking on water changes and it worked great!

expensive!

For what you’re getting, this product is outrageously expensive. Get a $6 5-gallon bucket and some instant ocean. Add a splash of dechlorinator. Mix with tap water. Done.

Free delivery

Liked the plastic jug the water comes in. Easier to handle than the other brand. Received 2 - 50lb bottle s of water with free shipping in a reasonable period of time. Big bonus!!

It's saltwater

gave a 3 star, simply because of price point. I needed it and didn't wanna make a 2hr drive or appointment to visit the closest aquarium store.

Great for quick tank set up

This made setting up a salt water tank so quick and easy. Now with a smaller tank makes a water change easier too. Less stress on fish and you!!
