biOrb Service Kit Includes 1 Service Kit, 1 Cleaning Pad, and Water Treatment Packets

Great product and works well

I love these service kits and being able to easily and cleanly change them out regularly. They fit any biorb aquarium but need to be changed more often for larger bio loads.The filter quality is a medium permeable sponge allowing for the filter to potentially get clogged if not changed regularly enough but not so fine that they clog in a week, which would cause it to lose suction.I change my filter out once a month but keep healthy bacteria with a coarse donut shaped sponge (cut to fit) surrounding the bottom around the filter as a pre-filter that doesn’t need to be changed except every couple years.

It was not clear what this kit included or didn’t include and I was reluctant to purchase if this only included the sponges ( similar to some third parties that don’t include the charcoal) but this kit was better than expected for the price! Actual biorb brand so you don’t have to worry about fit or function. Includes water clarifier as well. These replacements are pricy but I find even with 10 fish in the tank I only need to do an 1/8th of a tank water change every 2-3 weeks as long as the filter ( and carbon) is changed out every 6 months or so. To me the time saved in tank maintenance is worth the 5-10$ extra it costs to buy the set.Scrub pads work great. Wish there were more but they can be used a couple times.Water clarifier, honestly not much value added ( especially if you do water changes regularly). But if you find that you stir something up when you move decor or catch a fish this will clear it up quickly.Packets for water treatment are ok. Care with concentration. It has put a fish into shock once because it hadn’t mixed in well enough.

You definitely need to remove your fish, decorations, and a significant amount of water before you can change the filter. You simply rotate the bubble tube to take the old filter off and put the new filter on. The algae towelette is tiny; I was only able to clean 1/3rd of my tank with it. I own 8 fish tanks ranging in size from 2-10 gallons, one of them is a 4 gallon spherical biorb. I use a master test kit to test the PH, nitrite, nitrate, ammonia levels in my tanks and the water quality is consistently the best in the biorb tank, which is why it’s easy to forget to change the filter on time! The filter and its design is the best, I love it

Expensive to change every 6 weeks.

Was just as expected. This kit has everything you need for completing a water change and really makes aquarium up-keep seem simple and easy. The kit contains a cloth for cleaning the aquarium walls and I love it! If it wasn't for the higher cost of this filter (although maybe worth it for ease of use) as compared to other aquarium filter refills, I would probably buy a new service kit for every water change. Instead, I bought one service kit/filter cartridge in addition to the filter cartridge I received with the aquarium. I rotate between the two filter cartridges by disposing of the old carbon and rinsing off all the filter components. I then bought some fresh active carbon and zeolite that I use to refill the cartridges. I have only performed 3 water changes so I have not been using this system long. I expect in time I will purchase more of these service kits as the sponges wear out.As a side note, I have been able to reuse the cleaning cloth twice now by rinsing and air drying it between water changes. I also bought a separate bottle of water conditioner. However, this kit contains all the water conditioner you need so if you buy a new service kit for each water change you are good to go.

I think its nice that is easy to just pop out the old filter and twist on the new one. I dont use the Biorb water conditioner or booster, so i do not have any thoughts on if it hurts fish like other reviews mention..but i prefer imagitarium brand water conditioner and biological booster from the petshop..works perfectly. Biorbs seem to get dirty fast if you over feed fish too so Id be mindful of that. Great value will keep buying

quality is there and it fits our fish tank
