Chipped Drain Holes, is this an issue?

[BigJohnny]

Hey Reefers,

I have been in reefing for 2 years yet have never used a reef ready tank! Sad really. Just bought a house recently and am firing up a new 90g RR/40b sump build. So, to the point:

Are these chips on the drain holes (came from the store like this and I didn't notice) going to be an issue? Whether that issue would be improper seal or eventual cracking/failing of the glass?

They are on the underside of the tank (dry side) which I believe greatly reduces the chance of any seal issues I will have since the gasket/flange is on the inside of the tank, but I really have no idea. I am more concerned about cracking/failing etc but would prefer to avoid both lol.

The first 4 pics are of the underside, the second 3 are from the inside.

As you will see, the top rings of the holes are normal circles, but the bottom on the outside/underside is chipped, more so on the larger 1" hole. I am showing you pics from the top just for a different view.

Any help would be GREATLY appreciated! Thanks!

It's fine I also had them on my tank. I did the plumbing. No problems whatsoever.

Great! Did you try to support the drain line plumbing in anyway or does it just come down from the bulkhead into the sump. I plan on using 2 45s, 2 unions, and a gate valve on the 3/4'" drain line, and 2 45s and 2 unions on the 1" emergency drain. Hard pvc in between it all.

Has anyone else dealt with chips like these before?

The only pipe that is supported is the the return from the sump. The two pipes coming from the display tank are just hanging but I did use pvc cement, so no way are they coming off no matter how much pressure is applied. And my setup is 220gallons

Chipping is common......when one does not know how to drill properly. these small chips are generally not a problem at all.

OK great. Yeah I was surprised to see a manufacturers tank with chips but as long as it's OK I don't care. Thanks for the additional reassurance.

My first tank I drilled. The first hole came out beautiful. Thought this is easy. Second put more pressure and got chips. But no issues at all. Worked fine.

the gasket on the bulkhead will easy care for this. You have zero to worry about.

Thanks everyone!

I had similar chips. No problems. Bulkhead gaskets cover a multitude of sins.
