I buy lots of stuff for my aquarium but this stuff has to be the best.  Super good for my money.  One bag of this in your filter and before you know it your fish are floating.  Where did the water go? I don't know?  Its so clear and clean Purigen is like magic.

This really works! It helps me cycle a new tank and definitely helps the fish adjust and stay healthy. I wouldn't start a new tank without it.

I was looking for a small fish tank and I bought this one.  I've been reading about how important is to keep a fishtank's water clean for keeping a healthy environment for your fish and  I'm very impressed of the quality of this product.  With just a 20% of water change weekly your fish will enjoy a very healthy and clean environment.  The filter works great, it suctions all the small particles that stay floating like rests of food, or rests of living plants, so if you want a low maintenance fish tank, this is the one for you.  Make sure to follow the instructions for installation and periodical changes of the filter's components.  I highly recommend this product!

If you are on the fence on buying this,  click add to cart immediately. This is the best thing for fish keepers. If only I had this when I setup my 38 gal tank with sand. I would've easily saved 2 hours or water changes. Hooks up easily to the faucet and makes water changes bucket free. No more heavy lifting or spills. Order ASAP!  If I would've got this year's ago I would've saved precious hours of my life I've wasted doing water changes. We all know time is valuable in our lives.

I'm obsessed with this. Buying more for larger tanks. Fish love it. Fry hide in it and I don't see them until they are out and about with the community. Will be buying several more for larger tanks. I have one in a 20 long and it's perfect! No algae has grown on it since putting it in 90 days ago.

I have bought this product locally for over eight years, and have used it in my 90g Reef Tank and 3000+g pond with 25' stream. This is one great product for increasing water clarity, minimizing string algae, and promoting fish health.

Be sure to "shake the bottle" to disperse the beneficial bacteria before pouring the required capfuls into your aquarium or pond. This is truly a great product! Over eight years use and no complaints. I am now using it in a 40g South American tank (dwarf Cichlids, neons, plants - low pH stuff) to reduce turbidity. :-)

Caught the fish I needed to get out in one day. This thing works. I had a Spanish Hogfish that was causing havoc in my reef. Right away when I put food in the trap he started to inspect it it wasn't long before he was going in and out of the trap wiithout a care. I was able to catch the fish without harming him and stressing out all my other fish and now he is in a tank that can handle him. Great product worth every penny.

This is by far the best filtration media available on the market I removed it for one week pH and nitrates spiked tank turn green. I added it back to me filter between the micro sponge and bio media within 24 hours to tank with Crystal Clear pH came back to normal and nitrites disappeared the stuff is amazing the trick is you need to neutralize the resin every 5 days I take 8 ounces of water pretreated inserted into the microwave for 3 minutes then mix it up with API salt and let it soak for four hours this release is all elements from the resin 3 neutralizes resin and makes filter media brand new you may keep using it over and over so far it's been 2 months I have a 20 gallon tank haven't lost a fish worth every penny!

This is the only thing that helped me get rid of the camallanus worms that plagued my poor fish for months. I lost so many and tried so many other meds. They developed secondary infections because of their low immune systems on other treatments.

Honestly, this cured everything in the tank.

If in doubt, don't risk your fish's lives but get this stuff.

I have a 20 gallon tank. One tablet is enough to treat 10 gallons. Also, the fizzing is nice to watch. There is no residue left like other fizz tablets end up leaving.

One pack comes with 8 tablets. I needed 2 tablets for my tank.

Oh and the instructions are confusing.

So, basically if you need to treat your fish or need to add new fish whose health you're worried about, add the tablets into the tank according to the gallon:tablet ratio. So 10 gallons to 1 tablet; in my case with 20 gallons, I needed 2 tablets. Then, after it's done fizzing leave that in for 2 days, without water changes. After two days, if you feel you have a long running infection in the tank or the fish seem not to be improving do a 25% water change and add a second dose. And then leave that new dose for two days. After that, do a water change of about 25% and that's it. You are good to go.

MarinePure works great on my marine tank it works 10 times better then live rock and every other filter media I have tried. I highly recommend this for all aquariums it is amazing I can't say enough about it. But I was battling ammonia and nitrites in my tank and a week after putting the marine pure in my tank my ammonia and nitrites went down to almost nothing.
