Good water conditioner
I used Seachem Prime for years and wanted to try out something different. Itâs very similar to Prime. It removes chlorine, chloramines, and detoxifies ammonia, nitrite , and nitrates. Itâs your handy friend when doing fish in the nitrogen cycle. All you have to do is add fish and use this product along with beneficial bacteria, and you should be good to go! I recommend this product over Seachem Prime. Btw fish in cycle is possible only if you know what youâre doing.

It works.
It works just like another brand called prime. But it also gets chlorine out of water which prime does not. I’m happy with the product and it works as I used to help cycle my tank with some fish in it.

You can never go wrong with Fritz
The whole line of Fritz products are solid. I use their water conditioners pretty religiously, as well as a number of other products. Never had a problem with any of their products and fish are swimming normally not Belly side up on the surface of the tank. Definitely a product line to be trusted you won’t find a better quality anywhere.

It’s ok.
Smell is really strong I should wear face mask next time because it makes me cough.

Love this stuff
This stuff is great keeping my water quality in balance. I use with every water change, and it only takes a few drops. Perfect if I need to lower ammonia or nitrite spikes.

Calling all newbs
This is a top-notch water conditioner by an elite aquarium potion company. Fritz Guard has supplanted Fritz Complete as my standard potion, however I keep both in the fish cave and will continue to keep both in the future. The products are both high quality and have some overlapping purposes, however they also have differences. If you are a newb fish-keeper, Complete is probably the way to go given its ability to neutralize the harmful fish waste compounds. However, once your tank/filter is established and you are more experienced, switching to Guard makes more sense (or I suppose you could use both concurrently). At least that’s my story and two cents. Recommended.

Works good without PH falling
Works without causing a pH drop and exhibits no adverse effects on fish. An added advantage is its long-lasting concentration, which also addresses nitrate levels in established tanks and ponds during water changes. Ensure accurate measurement as lesser quantities are required compared to other water conditioner brands. Particularly beneficial for small koi ponds and larger tanks due to its prolonged concentration.
