The Cetus sieve is a totally new, bow screen pre-filter, made using the latest rotational molding technology. With all of its benefits and build quality, it is undoubtedly the best of its kind on the market today, regarding quality and performance! It is designed to efficiently and effectively remove large amounts of mechanical waste from a pond. It can be set-up gravity OR pump fed and has many benefits over the original bow screen technology.

This Cetus has a variable inlet height using the unique patented Pondflow regulation system – for use when gravity fed. This allows water levels within the pond to drop without causing the circulating pump to be starved of water. The Cetus will allow a skimmer or a bottom drain to accept vast amounts of waste without excessive cleaning needed to be carried out. The water must then be pumped to either a normal filter above pond level (Nexus Eazy/Eazy Pod) or to a pressurised filter.

If pump fed, the sieve is placed above pond water level and then the exit water is gravity dropped into your main filter.

The Cetus sieve is a bow screen pre-filter, suitable for pre-filtration of any biological filter including all pressured filters. It is advised that all pressurised filters be pre-filtered using a Cetus to reduce excessive backwashing and maintenance due to heavy solids.

It worked!
Set name: 10 Jumbo, Set name: 10 Jumbo
I bought this to fit a full size 4" memory foam mattress topper. I gotta say it took 3 of us. 1 to lay on the memory foam and 2 of us to get it shoved in and keep pulling the bag up. But it actually fit! My arm was dying using the hand pump so we used a vacuum. It worked better than the hand pump. Due to what I was storing it did not shrink very flat, but compared to the size of the memory foam it shrunk a lot and will definitely save space! The bags arrived today so I dont know how well it holds up long term but the bag was very sturdy yanking it up around the foam. Didn't tear or stretch. And it actually fit!

Air comes out and STAYS out!
Set name: 10 Medium
I’ve tried so many different versions of these vacuum storage bags over the years, and this company seems to have finally figured it out. They’re absolutely not exaggerating about the 80% space savings. What really impressed me is the pump design — it actually screws onto the bag, so it stays securely attached while removing the air instead of constantly slipping off. It also has a stop valve built in, which prevents air from escaping when you remove the pump to put the cap back on. Such a smart design improvement over other brands I’ve used. I bought the medium 10-pack to store my winter clothes in two 66-quart storage bins, and they fit surprisingly well. That said, part of me wishes I had also picked up a few of the smaller sizes just because they’d probably make stacking and organizing even easier. Overall though, I’m really impressed with the quality and design.
