It's a really small particle GFO so you'll need to use a "very fine" mesh bag. Use an 1/8 to 1/4 cup for 30-40 gals. Rinse it and place the bag pretty much anywhere in your sump's flow/return. It works wonders with phosphates! Replace it every 4 to 6 weeks. I've also mixed it with activated carbon, mix about 1 part GMO to 2-3 parts carbon.

Q: Where should I put this in a Fluval evo 13.5 gal tank? And is it good to mix with activated carbon in a same bag?

Thank you for your question! The media works well inside a fine mesh bag, well rinsed, anywhere there is decent water flow (like where you would place a carbon bag). This media can be mixed with the activated carbon in the same bag however, the GFO stays active longer than the carbon so that would be the only drawback. Please let us know if you have any other questions, we are happy to help.

Q: It says it can be used in pools. Are there dosage recommendations on the package

It says 1 - 2 grams per gallon in a fine mesh bag. I use it in my 35 gallon saltwater tank but I'm not sure how much it would take in a pool.? The jar has 454 grams in it.

Q: Can this be used in a reactor?

Hello, thank you for your question. This product can be mixed in reactor with carbon or used by itself. Please let us know if you have any further questions! The Kolar Labs Team
