I would never trust acrylic for something like this, especially the threaded ports. That is one plastic that can crack when you least expect it to. Are you doing this just for the fun of creating something like this?
The only other option i have is using brass nickle plated barb.
Which i dont think i can really use because i want it on a shrimp tank.
i could soak the barbs in water and leave it there for a week and see if i get any metal leeching out as a test.. i do trust the nickle plating on the attachments i have... but i wanted to leave all the metals out if possible.
These ghost fittings are somewhat durable.. as long as i dont use it as a hammer or kick it around or put unneeded force on them.
I can also get poly fittings... but it would look kinda funny as well.
Last course of action for me if all fails is to get a 1/2ID or SS tube which i can source.. a small one and just Silicon it to the pump head + bottom attachment.
And no im making it to make a nice Shrimp tank... lol...
I have the rimless... gonna copy Liam's undergravel, and i was intending on using that complex as the pump.
Seeing how shirmps dont require a super filter... i wanted something that more looked nice.
No, it will not make a whirlpool in your tank. The max discharge is only 120 gph. That is a fairly low flow rate. Given the higher max head pressure, it will probably fall off much less than your average impeller pump.
thought about this too, but the head pressure on this DDC vs a regular pump is almost by a factor of 3x!
Basically its a little giant in headpressure with a GPH of a Rio... :X
Anyhow going to keep the tubing to 13mm inside diamter.. or 1/2ID.
Waiting for ehiem substrat pro, and some other stuff to fill in the tube, as well as some blue sponge material as a course filter.
If im lucky i should have all the parts by friday and i can do a run test on it.
Jeez, bro, mixing two different hobbies together!
What size tank is this going on?
a 10 gal rimless... and i will use colder high flow no spill Plastic QDC's to make maintenance easier.
I am mainly doing this because i have all these parts just laying around in a box from my other hobby which sits unused... and i need a filter.
if you guys saw the LC toys i have that sits there, you'll think good lord... what has he been doing...
This is the spare fittings i have alone... and its actually bigger as this is an old picture.
