K1 Filtration for rays plug!

  • We are currently upgrading MFK. thanks! -neo
I fully appreciate the lengths you've gone to on this thread. The evidence supplied in the form of pictures. I understand we were apprehensive and somewhat dismissive at first, thanks for enduring and continuing to explain.

I'm going to look online and try to email Kaldnes with this thread and information and see if they will respond or provide any information. I think this warrants more research. There is a lot at stake here.
 
Could be related to the way people are running it in their system. Hard to tell from pic but is that a pump strainer basket it all collected in? If plastic media is constantly pounded at a high flow rate against rigid screen it will most likely break down at a more rapid rate. Smooth boil and single centered or multiple outlet points to prevent bunching up are what spec sheets advise.
 
They have a massive 8x3 ish sump with quite a fast "boil", it seems to have made it through the screen. It was fitted out by an proper shop fitter I believe.
 
I dont mess with egg crating, mesh, over, under or around dividers. I buy .25" acrylic sheets, cut dividers out of it and drill 5/8" holes completely covering the pieces works great.IMAG1328.jpg

I really like and enjoy the creativity here. The only thing i would caution is placing an acrylic divider firmly into a glass tank. Acrylic absorbs water and swells for the first 4-8 weeks once submerged. It gains some slight size during this time. If you wedge a piece of acrylic firmly inside a glass tank it can expand and blow the glass side panels after some time. Panels that thickness might only expand a millimeter or two but that could be enough to cause glass to fail. My friend had this happen and was a disaster, led to major losses. Many people use suction cup anchors to allow a gap for the expansion. Or cut the acrylic smaller than flush, and fill the gap between the glass and acrylic with silicone to allow for expansion without putting pressure on glass.

Not trying to be an alarmist or critical of you brother as you have my most respect. If you have been running for some time without issue that's good. But if this is new and you haven't run it yet I want you to be aware there could be potential for accident if the internal acrylic is firm fitting inside of the glass tank.

Appreciate the advice as I wasnt aware of that. But with that being said. I dont ever get them cut that tight thus the clamps holding the acrylic until silicone sets. Every sump has been set up this way for at least 4 months to 4 yrs.
