Prorezult Generic 6 x FRF-025 COMPATIBLE SERVICE KITS Fish R Fun Replacement Filter Media SAVE £££s COMPATIBLE SERVICE KIT (2 x Service Kits = 6 Refills) EQUIVALENT TO 2 ORIGINAL BOXES

So far so good for my fish tank. They do fit the small units. Mine take 4 so I have two spare. Great price.

It's gd as replacements. I thought that they came in the cages but it's just the inserts, sobmake sure you have some cages to put them in.

Thank you so much for these, they fit perfectly in the little cages. Also, love the easy instructions. Easy to pop open plastic cages, clean and pop in new filter material. Will definitely be buying again.

Not clear description for which type of filter can be used , not for cleaning, used for 1 months and the cartridge needs to be replaced.water clarity is good for 2 weeks. After more solution needs to be add .

Been using these filters for a while now. They're easy to change over and do a great job of filtering water through the pump. Ordered these on Friday 11th Oct. they arrived Saturday 12th, brilliant service.

First time using just a refill and it is simple to do and works out cheaper

Quick delivery but seems the 2 boxes are missing. Only the 6 filters are included.

Works well, does what it says it does but I purchased the wrong one so instead of having some spare, I had to use all the ones in the pack for my filter.
