Instant Ocean Marine Conditioner 250 mL, Makes Tap Water Safe for Aquariums

Best value I’ve found. This same solution is usually $10-$15 at any pet store.

It is a very big bottle that provides many gallons worth of conditioning. It is very easy to use and seems to be very good for the fishes. Accidentally dosed some to freshwater and doesn't work well so do be aware. Otherwise works well and at a great price point for such a product.

I can definitely see a difference using this in my tank

The product works as described.My only complaint is that it's very difficult to make small quantities. If I may suggest a change... I wish it had a drop-tip, where I could place, let's say, 7 drops per gallon. Instead, I am forced to make a minimum 5 gallons (or improvise), using the measuring cap. Also, it would be nice because the drop-tip could be made removable, that way people who want to make larger batches, can simply unscrew it.Other than that, it does it's job, five stars from me!

Tastes gross, but it works well.

Worked great got all the hard metals and such out of water and has simple instructions would recommend getting bio-spira with it to make your tank healthy and have good bacteria in it.

There products are the best in the marine game I wouldn’t know if this works good or bad and pretty tough to review but I trust instant ocean for all my marine aquarium needs and trust it’s doing what they say it does.

Recommend highly prices are way better than going to a store way cheaper and no hassle with masks into stores does the job perfect !.
