External Aquarium Filter - For the Highest Demands
- EasyClean pre-filter module – Module can be removed separately from the rest of the filter. This reduces maintenance, increases filter efficiency, and extends the life of main filter foams. Customize the pre-filter with coarse 30 ppi, fine 45 ppi, ultra-fine 60 ppi, and activated carbon 45 ppi filter foams
- No mess maintenance – Integrated safety locking features on the handle, pre-filter, and check valve in the inlet/outlet connection unit, ensure no accidental spillage or messy maintenance
- Sealed filtration pathways – Allows for the full benefits of all four stages of filtration through this intuitive design
- Hel-X Biomedia – An extremely large protected settlement surface (800m²/1000 liter) that allows beneficial bacteria to grow and thrive. The material is designed to stop floating as soon as it reaches a certain level of bacteria colonization.
- Carbon pre-filter foams – Activated carbon absorbs unwanted substances in aquarium water. Carbon filter foams make replacement much simpler than using common granular carbon.
- Adjustable flow control – Flow can be adjusted for the inlet and outlet in multiple locations on the filter assembly

- Quiet operation – Sound dampening design

Sizing is way wayyy off.
Size: 5T, Color: Beige
I ordered three of these in different sizes for my 5yro&7yro -They’re average to their age sized kids.
So ordered size 5 for my 7 yro (I read other reviews on it being big). Everything fit except the pants we’re closer to a size 8 (I ordered a size 5 remember) so disappointed.
And a size 4 for my 5yro. The size 4 pants fit my 7yro! But not my 5yro at all. The rest of size 4 outfit was only a little big but not big enough to trade up to the other child. Unfortunately the gigantic pants are beyond the problem. They are definitely running 3 sizes too big. They’re not even something I could fix with my sewing machine. Company says they’ll work with you & send one item “free”but then say their shipping & handling fees are more expensive than the suit. Feels like it’s a ploy.
update, the third suit arrived after a month of waiting and its a size 3-well its supposed to be a size 3. The pants are the size of an 8 year old. Im pissed. it's now past the return date, I have 3 suits for $45 each, and I had to rig the pants to fit my 4yro for my wedding. looked like crap obviously bc an 8yro's pants don't fit a 4 yro.. Don't bother buying from this company unless you're buying for an absurdly proportioned person.
