Seachem 437 Prime Fresh and Saltwater Conditioner - Chemical Remover and Detoxifier 1L

great product this is all i have used for fish for over 15 years now

Have 5 tanks. 125, 72, two 20’s and 29 so far used it in all of them. Never had issue with this product not preforming. From adult breeding pairs to their fry. Use it on all my tanks.

Does the job good

I always use this product I find it to be 100% better than the standard tap safe

Working great on my marine aquarium you saved the day my fish where on there last legs or fins I added prime and they are looking good it came a day sooner

When my local large conglomerate pet store decided to stop selling any kind of decent sized water treatment, I turned to the one place who I knew would have it for a deal.

Great 1ltr for a fraction of the price

I’ll always buy this product A++++

This will last you a super long time. Can of pop for size comparison.

Works perfectly for its intended purpose
