SeachemPristine Bonus +30%Free 325ml, 12

Unfortunately I got my bottle very hot from being in the sun, the seal was broken, this said, the seller was extremely understanding and professional, accepted to return it, I have trust in them and buy from there again

No a miracle cure but I'm surprised that it actually works. GIVE IT TIME! This bacteria needs to establish it self and needs time. I started using this over the last 3 weeks, adding every so often. Water started becoming crystal clear, swamp/algae smell had gone away. Aquarium looks cleaner as well. New algae stopped growing and the old is being suppressed in to certain places only. Now it's time to syphon out the left over mum and clean the old algae way. Highly recommended product to help stabilize the aquarium.

This only had 2 months til it was out of date, ok if u use lots and have massive tanks, I do not, sent it back! Amazon really P me off sometimes! They are like an untrustworthy E-Bay seller. For such a large company their dealings can be a bit of a con! I expect better service tbh

This works, couldn’t get my nitrites and nitrates down until I used this

Out of date

I think it does what it says, dont have a way to validate, but i think it definitely cleaned my aquarium. It also solved algae issues for me.
