Good. Been using this for the tanks. Good price stacking vouchers during 25 sale. Only thing is of the three products bought only one has the expiry date visible. This time trying the rhino edition which sounds better?

AMAZING
26 February 2020

This is amazing. Our 4 year old tank has never truly been clear. We've tried everything. We only have a few fish, we clean, we do regular water changes, we have tried several filters, we make RO water, tried several products, everything. I happened to find this on saltwateraquarium and since everything else buy here is great gave it a try. Within a few days we could see the difference. For the last month the tank has remained crystal clear like never before. AMAZING

Every tank needs this!
10 June 2023

Pristine is a game changer to keeping a crystal clear aquarium. I would spend countless hours wiping the glass and no matter how many water changes it still would get this awful foggy appearance in the water and on the glass itself. Since I added Pristine to my tank my water is crystal clear and even the fish and Mystery Snails appear more energetic. My tank is now absolutely beautiful and I am really enjoying the hobby more!

I swear by Seachem Pristine!
28 March 2019

I love this product! My tank currently has five female platies that are big eaters and are huge waste producers. Without a really good cleanup crew, their food sometimes sinks to the bottom and just sits and yucks up my tank. After a while, detritus worms started to thrive! I started using Seachem Pristine during every water change and the worms disappeared because the bacteria has been eating up their food source (old fish food and my platy's waste). I will continue using Seachem Pristine during every water change!

Review of Pristine
5 May 2024

I always use a bacterial sludge reducer when after a partial water change. Not sure how effective they are at doing what they’re supposed to do, but gives me peace of mind to do so

Pristine is helping get my tank in balance! Even the Diatoms (brown algae) are disappearing! This is the third Seachem product I've purchased at PetCo. The suction cup ammonia and ph monitors really make it easy to monitor and give you peace of mind when going through these phases that tanks sometimes do.

Seachem Pristine Natural organic waste management Rapidly and safely eliminates sludge and detritus Helps increase water clarity Marine and freshwater Pristine uses bio-augmentation, a non-chemical and natural method, to improve water quality. It provides bacteria that break down excess food, waste and detritus in freshwater and marine systems. It will also reduce excess nutrients (e.g. ammonia, nitrates, and nitrites) that may fuel the growth of nuisance and disease-causing organisms. Pristine increases water clarity and promotes overall better health for the aquatic environment. The bacteria species in Pristine thrive in fresh or salt water and can utilize a wide range of organic compounds, including fats that can cause unsightly films. Unlike traditional nitrifying bacteria, this bacterial blend can adapt to harsh or low oxygen environments and continue to multiply and improve water conditions. Biopolymers produced by established bacterial colonies trap particulates and increase water clarity. The species of bacteria in Pristine are a unique blend, specifically developed for hardiness and their ability to adapt to a wide variety of environmental conditions. Directions Shake well before use. Turn off UV/ozone. Use 1 capful (5 mL) for each 40 L (10 US gallons). Then use a maintenance dose of 1 capful (5 mL) per 80 L (20 US gallons) with additions of livestock or the disruption of the biofilter through cleaning or medications. Antibiotics should be removed with fresh carbon and a water change before adding bacteria. Allow 2 or 3 days for the bacteria to become established before using UV sterilizers or ozone. Recurring problems with high nutrients can indicate overstocking, overfeeding or inadequate filtration.
