Great product BUT watch to change in 4 wk
This is a great product if you do not have reactors or heavy stocked tank only problem is that it states that it last longer than I have found that it truley last. No matter how sparse or heavy your tank is on contents of any kind of coral or fish. This product last between 4 to 6 week I lean closer to the 4 weeks I have placed this is area of really good flow in a basket made to hold bagged contents for this purpose and after 4 weeks even repositioned my test start to change that indicate it is exhausted how ever the ferric oxide will last till 6 weeks. it tapers to no effect;starting at the end of 4 weeks then zero by 6 weeks for my tanks. But changing this out approximately between the 4 and 5 week absolutely week 6 it does an awesome job. This product does cut out having to have separate bags for charcoal and ferric oxide plus no mess so every month is worth it I just wish they would state 4 to 6 weeks. I also use purigen which with this is great and that product doe change colors when it exhaust( note in separate bags as purigen has to have a 180 micron bag and the amount is really small and the exhaust time is dependent on the AMOUNT of contents needing to be absorbed at the time of use ). All and al for tanks 75 gallon specially cubes 30 gal or less this product is AWESOME!

Not sure it’s good but may cause big phosphate swings if not used carefully.
I think this isn’t the greatest idea for smaller tanks unless you always use it and replace the media fairly regularly.I don’t think it’s a great idea to drop these into smaller reef aquariums that have algae because sudden phosphate swings may actually be detrimental to the system. If you do have algae in your aquarium already, this isn’t a great idea. Adding so much phosphate media will remove the phosphate suddenly and you run the risk of crashing the algae population and causing contamination with other organic pollutants and ammonia swings as algae dies.If you do want to use this media, you either have to use it in larger systems (50 Gallons and above) or you have to use it all the time from the beginning of the aquarium life span.

I am a firm believer….
I used this product on both my 75 and 125 freshwater aquariums. They were both a little hazy – and literally within 2 hours of adding these media pouches to my canister filters the water was clear as could be for both tanks. No negative impacts to the fish either. I will be using this product as needed as long as it is available =)

Extremely clear water
I totally forgot to soak my new driftwood and it was too late when I checked the next day. All the tannins leached out and I could barely see the fish. I did water changes for the next couple weeks but it barely helped. Once I put this in, the next day it was a little clearer. After a week, it was crystal clear. The white sand is now pure white. Works like magic.

El producto al abrirlo esta humedo, como si ya hubiera sido utilizado, al limpiarlo bajo el grifo no suelta el polvo del carbon como suele ocurrir en este tipo de productos.Decepcionado con el producto.
Jeff –
I used this for a month in my Innovative Marine Nuvo Abyss and it works great. So far it has been a little over a month and I haven’t had to replace it. Crystal clear water with 0 nitrates and 0 phosphates.
Roland K. –
Crystal clear water, low phosphate and nitrate levels and even strongly reduced heavy metal levels as confirmed by OES-ICP. In my tank it lasts for approx. 8-10 weeks.
Robert Iley –
This product is excellent for water clarity. Please read the packaging, because it states that it is packaged wet, and is made from low-dust high-grade carbon, so when you rinse it, you will find that there is hardly any residue from the material. My tank was cloudy until I put the bag in my sump, and the water cleared up in no time. Definitely value for money.
