    jnad algaescrubber II

    Hello!

    Finally, I finished my new algae scrubber.

    Preface:

    In this project, I focused on security when it comes to leaks and water on the floor, so I have chosen to use a pvc box purchased in a local shop as a basis instead of gluing plexi / alryl plates.

    Because the scrubber is placed on top of the aquarium, I have chosen to create a 1-sided scrubber so that it build minimum centimeters out from the wall that the aquarium is located at. This leads to the scrubber will be wider, but for me it is important that the scrubber is very slim and as less centimeters as possible out from the wall. Scrubber builds approximately 9 cm from the wall, but I had to make a little "edge" of the outlet because I have a pretty wide glass strip on the top of the tank that the outlet had to reatch over. This lead to that the total depth of scrubber was about 11 cm, but a aquarium that not have such a wide top edge so it's enough that the scrubber is made 9 cm deep.

    The outlet from the scrubber should be the most block-free so that flooding due to blocked outlet is avoided. The outlet should also be 100% silent and does not provide microbubbles to the aquarium that are often a problem with outlets of the pipe type. I believes that the construction of this outlet meets these requirements, over time, I have tested a similar "temporary" outlet on my existing scrubber, and the test looked very promising.

    The scrubber should have a construction that provides adequate ventilation / cooling of the fixture without the use of cooling fans. The scrubber is designed so that it will flow enough air in at the outlet and past the light armature to keep it cool.

    This scrubber is very flexible when it comes to the size of the screen and light. One can easily customize parts, ie the size of the screen lighting according to need and still use the same scrubber.

    When it comes to capacity so I think this size scrubber can meet filtration needs for feeding in the order: ½ cube - 2 cubes of frozen for a day. This depends on what equipment you select to install in scrubber, screen, lighting and of course the amount of flow.

    Technical specifications:

    Width: 36.5 cm
    Depth: 9/11cm
    Height: 15 cm

    Lighting: 1x24W PL-L w / remote ballast
    Flow: NewJet 1200, I will customize the width of the screen to match the flow that the pump delivers.

    Maximum size of algae screens and lights in the scrubber are:
    Display: 35x11 cm
    Lighting: 2x24W PL-L w / remote ballast, (this is not tested, maybe or maybe not you have to use cooling fans.

    Scrubber is not running in the aquarium now, but has been tested in the sink and everything looks promising.

    Here are some photos:

    The scrubber will be run on the aquarium in a couple of days, i will return with some uppdates when the scrubber have been tested on aquarium for some time.

    I would appreciate your feedback to this project.

    Sorry about my bad English.

    Quality build, just as expected!

    Hope it works good for you.

    Hello!

    Thanks.

    I've been a little unsure if the light with 24W power is sufficient enough. But I hope that the shape of the PL-L tube i am using with about 50% of its ovn surface cover the Algea screen directly will have an advantage just like the T5 tubes compared to the regular stick shaped CFL bulbs that often is used in scrubbers.

    Is this a correct conclusion? or wrong?

    Hello!

    Just another question about 3D filtering:

    I have seen there have been some posts about 3D filtering on the forum, to satisfy my curiosity about this 3D filtering, I made a small glass chamber where the algaescreen fits right into it. This is a narrow chamber with internal measurments of only 16mm. The idea is that the chamber is placed under the beam tube so that water flows into the chamber at high speed and then flows over the overflow edge of the chamber and into the scrubber at its rear wall. Chamber will be placed with the lower edge facing the back wall of the scrubber, there will be room for the water to flow down the back and then again forward under the glass chamber making its way to the scrubber outlet. There is a open space between the bottom of the glass chamber and scrubber bottom for about 2cm to let the water pass through to the scrubber outlet. The glass chamber's highest edge is facing the light fixture and would also then serve as a splash guard.

    I call this: THE 3D ADD ON BOX

    What du you think, will this work??

    Not sure what this means.

    I don't get this either. Needs more pics I guess.

    I mean that on stick shaped and spiral shaped bulbs very mutch of the bulbs is sending light away from the screen and therefore have to relay on the reflector too send the light the right way (to the screen).
    The PL-L bulb shape is more like an T5 tube, more of the PL-L bulbs lightsource area is pointet against the screen.

    If i have right the regular stick or spiral shaped bulbs sends mutch of its own light into the senter of itself and backwards to the reflecktor.

    Sorry, have no more pictures right now. But the screen is simply submerged under water in the 3D box, water is flowing trough the box and light is shining on the screen trough the box glass wall

    The screen should not be submerged (except for a tiny bit at the bottom to keep the bubbles and noise down), it should hang in the air fully exposed to the light.
