good product

great product

Great

Cant beat this in your filter!

Great product! I run 3 of these in my salt water fish and reef tank and it keeps the water crystal clear. I only need to change the Chemi-pure every 3 months making it well worth the money. System is 125 gallon main tank, with MP40, (3) gen3 radion led, sump with live rock, Reef Octopus protein skimmer, mag 12 pump, chemi-pure, and I run a separate refugium giving me a total volume around 170 gallons. I keep SPS, LPS, lots of inverts, and 12 fish ranging in size from small snowflake clowns to large Mag Fox Face. All are thriving. Boyd Chemi-pure is the only product I will use for chemical filtration. Before the addition of the refugium I used Boyd Chemi-pure elite which is also a great product!

I have been using Chemi Pure blue for some time in my 100 gallon saltwater tank and never had a problem with it and have been very happy with the product. My most recent order I opened the containers and noticed it smelled like fish, I didnt think anything at the time. I rinsed before putting in my filters. The next day my tank was cloudy!! I did a quick water check and my nitrates were through the roof!! I had a severe bacterial bloom. I pulled both chemi pure pouches out of my filter and threw them in the trash. The bloom lasted 24 hours, Unfortunately I lost my beloved flame Angel and Fairy Wrasse. All of my other fish survived. I since have ordered more chemi pure and they smell like nothing when I open the containers. Do not use if when you open the container it smells like fish!! You may throw off your entire tank and potentially deal with fish loss.

Product does what it says but throughout the year I’ve had 4-8 bags burst in my sump, (I usually change every 2 months) can you imagine cleaning this thing out your sump and water column. SMH -won’t be buying this again as much I love it

Definitely recommend for any filtration system!

I placed the Chemi-pure blue into my 2 canister filters and it has totally cleared up my water.
