About Seachem Prime Fresh and Saltwater Conditioner - Chemical Remover and Detoxifier 500 ml
Overall Feedback:
95% positive
86% praised for its ability to control algae growth, though 14% noticed some regrowth.
After using the product, my Rainbow fish died and other smaller fish started to gasp for air, indicating that the product did not control algae effectively.
94% found it easy to dose and apply
The product is very easy to use.
I find it very easy to measure and use the product, with instructions provided on the side of the bottle.
Maintaining the aquarium with this product is super fast and easy. The steps for maintenance include removing 25% or 50% of the water from the tank and adding the dose before adding more water.
I have a tip for smaller tank owners to use the product easily without buying a syringe or dropper.

87% appreciated its safe and gentle formula
I used the product in a small 2.5 gallon tank with hard water and got neutral ph, soft water, and zero ammonia, nitrites, and nitrates readings at the beginning of cycle process.
85% praised for its ability to eliminate unpleasant odors, though 15% still detected some lingering smells.
The product has a sulphuric smell due to the chemicals in it, so it may not be suitable for those sensitive to certain smells.
I have seen the black residue and horrid smell from the bottle. Other reviews have reported the same issue.
After the third use, the product developed an awful smell that I can only describe as a combination of dead mouse soaked in vinegar and rotten eggs mixed with diesel.
I noticed a pungent smell in the liquid after a few weeks.

91% praised for its ability to clear cloudy water, but 9% noticed it didn't work as well with heavy algae blooms.
The product effectively dechlorinates water and reduces levels of free (toxic) ammonia by binding to it.
After changing the product to a different water conditioner, my fish have been normal.
