? about the diy overflow

[chesterthehero]

it was painful to watch me and my gf figure this out...

seriously... it took like 3 hours till we finally got it and then a whole 5 minutes to build it...


also... my pump is way oversized... im going to the store now...

I built one for my 180 about a year ago. I did a thread on it at another forum with lots of pics.

The longer drilled leg on right side sits inside the tank if your unsure what your looking at...

For the love of all things natural someone please explain the point of the red

After hours of pondering all I can assume is this:
- cap off the red uptube and you build a closed syphon. GL keeping this running as gravity takes over and it sucks water faster than the pump is replacing it.
- shorten the uptube to below the water level in the tank and risk a good ol fashioned mopping. This would be most likely if you used to small diameter of pvc.

How's my physics?

nice pic

ive never seen anyone butcher a pic of mine more then that pic

and whoever typed it,just cus you dont see a one way valve at that time wouldnt make anyone a retard lol

For the love of all things natural someone please explain the point of the red

its to let the gurgling noise out

its a vent,lets air out,lets air in,to flow more
thats my guess

 

[sypherz28]

How much will the diameter of the pvc alter the effect of the overflow? And what is the best way to fine tune the drain to the sump, and tune the flow back to the tank? I'm guessing a standard adjusting valve would suffice.

 

[Danyal]

don't screw with the flow through the overflow, that will be dictated by the return from the pump.

Got a trivial question, I just finished painting my overflow with Satin Black Krylon Fusion Paint. The question is how long do I let the paint cure? The paint instruction says that it dries in 10 minutes.

Would you guys say that it should be safe for me to immerse the pvc pipes in the tank tomorrow afternoon? Thank you.

Drying and curing are very different. Let it cure for at least 24 hrs before committing it to underwater use.
