LLS-35

Never before offered in the aquarium industry the LLS Sensors allow for the measurement of water depth in inches or centimeters.  Available in four different sizes- 4″, 15″ 23″ and 35″ each sensor has a special place in helping understand the water level in the sump, aquarium, reservoirs, and other liquid-holding containers.  No longer does one need to physically look to observe how much water level is above or below a specific point, but now simply open the Apex Fusion App and observe.

The LLS sensor can connect to any available FMM port in the Apex System.  Liquid will enter the plastic envelope around the thin material of the sensor.   Once the liquid is in contact with the sensor material the LLS uses a patented resistive sensing technology to accurately and reliably measure the liquid level in a container.

Included with each LLS sensor is a clip that allows for the mounting of the sensor to the side of the sump, aquarium or container.  Have a Euro braced sump?  Don’t worry you can simply mount the LLS sensor to a baffle inside the sump.

Later in 2022 Neptune Systems will release a magnetic version of this clip and a clip that mounts to a euro-braced sump or aquarium.

Generally the sensors respond to liquid level changes at a rate of about fifteen seconds per inch of water level change.  So if the water level was suddenly decreased three inches, then it could take up to forty-five seconds to reflect this change.  While quick depth level changes are uncommon in an aquarium, and, typically, changes  are reflected more quickly than this, for this reason, it is best practice not to use the LLS for immediate control needs— like auto top-off control.

Once calibrated the LLS is accurate to about two-tenths of an inch.

The largest of the LLS sensors is the 35″ sensor.  This sensor is to be used for large reservoirs that are often utilized for saltwater reservoirs for manual and automatic water changes.

The sensor aspect (the white ruler section) is obviously supposed to be in your water to measure depth!

But also no– The components in the head of the LLS are fully encapsulated in epoxy, but the LLS is not intended to be fully submerged. Care should be taken when selecting the proper length of LLS and installing it to ensure that the water level never exceeds the uppermost graduation mark.

100% Cotton Pillows .
Color: White, Size: Queen Size Set of 2, Color: White, Size: Queen Size Set of 2
These pillows feel soft and fluffy without being too flat. They provide nice support for the neck and feel comfortable whether sleeping on your side or back. After several nights of use, they still keep their shape well and don’t feel too warm during the night. The set comes with two pillows, which makes it really practical for the bed.

Luxury Comfort and Perfect Support – Best Pillows Ever!
Color: White, Size: King Size Set of 2
I recently purchased the Serta Hotel collection Pillows White Goose Feather Down Fiber Gusseted, and I couldn’t be happier with my choice! These pillows are the perfect balance of softness and support — plush enough to feel luxurious, yet firm enough to keep my neck properly aligned all night. The gusseted edges really make a difference, helping the pillow hold its shape and look full even after weeks of use. The quality of the materials is excellent — the outer cover feels smooth and breathable, and there’s no feather poking out like with cheaper options. I also appreciate that they fluff back up easily after use, making the bed look hotel-perfect every morning. If you’re looking for comfortable, high-quality pillows that provide great value for the price, I highly recommend these. They’ve truly improved my sleep!

Good quality pillows
Color: White, Size: Queen Size Set of 2
These are very soft and supportive as advertised. W find them a little too thick for my taste (why I only gave 4 stars), but personal preference is very subjective with pillows. They are well made and high quality, and am happy with my purchase.

Overall, not that comfortable!
Color: White, Size: Queen Size Set of 2
Only okay. I find these pillows to be heavy, and not very conforming. Overall, not that great.

goose down pillows.
Color: White, Size: King Size Set of 2
Since receiving them, these king-size white goose down pillows have truly transformed my sleep. They are incredibly soft and fluffy to the touch, so plush it's hard to believe they hold their shape. Sleeping on them is like lying on a cloud. The 100% cotton cover adds extra comfort: it feels cool to the touch, breathes well throughout the night, and helps me maintain a comfortable temperature while I sleep. Furthermore, the "reinforced fiber" structure is noticeable: after several weeks of use, the pillows retain their support; they don't clump or lose their shape, ensuring consistently good rest. I find they have the ideal balance between firmness and softness: firm enough to support my neck and head, yet plush enough to adapt to my posture without creating pressure. This has improved my nights; I sleep more soundly and wake up with less stiffness in my neck. In short: these pillows combine luxury, comfort, and durability. If you're looking to improve your sleep quality with soft, firm, and breathable pillows—especially in king size—these are perfect. Definitely one of the best investments you can make for better sleep.
