I would probably not use either one of those motors- they would probably work fine for a while, but they are just not built to last. And the torque will probably be really low. And for the same price you can have a medium quality used motor.Finally going to try to diy one myself.... I'd like some advice on motors if someone could help me out..
DC 12V 15RPM 6mm Shaft High Torque Turbine Worm Geared Motor https://www.amazon.com/dp/B00EDMIH7E/ref=cm_sw_r_cp_apa_i_n3uECbP3J1MQ0
Also what power supply should I get? I know I need to convert from ac to DC 12v.
How did you attach your motor to the acrylic.
Also think it's possible to burn a Gear into pvc. Aka metal gear heat it up and put it into the pvc to make a pretty permanent bond?
Sorry for all the questions. Thanks in advance
Thanks for the quick reply. How many amps is the motor you suggested?I would probably not use either one of those motors- they would probably work fine for a while, but they are just not built to last.

Any power supply will work as long as it can supply enough amps- I always just use something off a piece of electronics I'm throwing away
You can attach the motor with nylon screws, or just a big gob of silicon and lay the motor into it (I did this). Anything that would exceed the holding strength of the silicon would destroy the housing anyway.
As far as melting metal into acrylic, it can be done, but I would recommend against it. This is better done in nylon or PVC plastic. Acrylic is fairly brittle, so the teeth of the gear would probably crack the acrylic when stressed. Acrylic is really a terrible plastic for most purposes, except for it's one redeeming quality- it's optical clarity.
Allow me to say that's not correct. You can easily make it so copepods and other animals that are attracted to light go pass the filter while still filtering 99%+ of the water.. Heavy materials drop down but copepods swim towards lightsources. You can easily place a tiny tube of 1-2ml ID and trick copepods with light to go in it. Result is that they will be drawn to the light, get into that tube and get flushed. Another option might be to have x% of water that just bypasses the filter. This might allow some things to build up in your sump but the most part will still be filtered. Also keep into consideration that a too clean tank is always BAD. So having x% of the flow (even if its just 1%) bypass the rollermat is still a valid solution.there is no way to build one that will allow a bypass for copepods.
A possibility might be a deburring tool... I use it when I drill holes in Acrylic. May not be small enough for a ¼ inch hole.Drip Plate:
This is not a real drip plate, since it will be submerged in your sump, but the idea is the same. I made mine out of ¼’’ plexi. Holes are space randomly approximately 1/2 inch apart. I used a ¼’’ drill bit and chamfered the holes on one the filter side, although this is not entirely necessary. I can’t find a good off the shelf option, but if someone knows of one please comment where to find it. This plate can also be positioned horizontally if space is not a problem
