Seachem Zip Bag

Item was great.. but the package it came in wasn't even sealed.

Very good item

I bought this and unfortunately the one I was sent had a hole in the bag and the tiny white beads were all over my tank. I contacted them and I was sent another one. Once I got everything cleaned up and had the new one installed it worked great. It quickly made my tank crystal clear.

I tried the small mesh size but it does not hold Purigen. Very disappointed since I purchased twelve of these for Purigen for my 750 gallon aquarium. I guess I'll need to go back to Seachem's "The Bag".

Watch out for the sizes. Small, medium and large refer to the size of the holes in the mesh, not the size of the bag.

Quality is amazing plus the thinkness. I ordered these for my media which I’ll be using in my canister filter. They dnt disturb the water parameters

I use this for resins. I use it for phosguard when I need it, and Purigen. Works great!

Looking on their website, this product is reported as being compatible with all Seachem filter media. However, when I used this this with Seachem Hypersorb and Seachem Purigen, the media spilled out of the bag the moment I submerged it in a bath of RO/DI water.I am glad I tested it before inserting them into my canister filter, or I would have had a hard time cleaning out all the tiny particles!Not sure about other filter media, however I would not recommend using this product with either Seachem Hypersorb or Seachem Purigen. I went back to using 'The Bag' and that worked well.Update: I informed Seachem of the issue I had with their product and they promptly reached out to me and explained that there was a issue with a batch of their Seachem Purigen media which led to the media drying up and cracking, however this has been resolved.
