Your gasket already looks like it's may have an imperfection in it. It's too hard to tell from the angle of the pic, but if the chip doesn't go too far past that first raised ring in the gasket, it's probably not your problem. After you hand tighten, are you using a channel lock wrench or...

Also, since the tank is away from the wall, if you just use the gasket that came with the bulkhead and not use that gasket sheet, you should be able to see if the drip is coming from the tank or the overflow box if you fill the tank up to the bulkhead with water again.

Put the gasket up next to the chip and take a picture for scale. Does the chip cover extend more than 50% the width of the gasket?

Looks like a 3/8" (maybe 1/2") push connect. Get 3/8" stem to 1/4" push adapter. Double check size before buying https://a.co/d/1NyA682

Some overflows (especially slim models) require that to be done to fit the standpipe. Here's a pic of my IM25 with a Marine Modular overflow.

You can cut the bulkhead as long as the bulkhead extends 1/8-1/4" past the nut after it's been tightened.

I usually drill outside to in, but I make sure to clamp a piece of wood on the inside of the tank to ensure I don't push through with too much pressure at the end. Also, on smaller tanks, it's hard to go inside to out because my drill doesn't fit.

The nut should never have a gasket on it for the potential of twisting or torquing the gasket causing it to not lie flat. Your particular bulkhead model would be even worse to have a gasket on it since it is not flat would mostly definitely bunch up the gasket or worse, tear it. The gasket...

That's one of of doing it, but there's obviously a reason for the leak. If you have the time and you're not in a rush, find where it is and it'll make you feel more confident of your setup. Plus, it won't look fugly with a crap ton of silicon.

You have a picture of those chips in the drill hole? How big are they?

Doh! Before I even had a chance to comment! Speciosa are my bane. The speciosa I have now in my tank is from Thinh at Coral Exotica. Mine is still alive, still waiting for the color to come back though. But it's still alive at least.

Can't find the marine modular instructions online, but here are three other manufacturer's instructions. All put the gasket between the tank and the external box and none on the nut. Marine modular will be the same...

Having a gasket on the nut side can easily lead to the gasket twisting when tightening the nut. Having the gasket on the outside will stop the overflow box from leaking.

This is not correct. No gasket is needed in the external overflow box. Gasket in tank between flange and glass and gasket between exterior of tank and exterior of overflow box.

The box is made specifically made with that offset on the top of the box to accommodate tanks with trim. Did you try different bulkheads? Assuming that the box itself is not leaking, using two gaskets on each bulkhead is plenty for it not to leak as long as there are no large chips on the...

I have chaetogro on a Versa doser sitting on a magnetic stirrer. Stirrer turns on a couple minutes before dosing. If you're going to auto dose, I'd recommend doing the same as sediment does settle on the bottom fairly quickly.

Slight chips are not bad. Chips that will need silicon are ones where the gasket does not have enough completely flat surface area to create a seal. I've made some nasty chips that I wouldn't think would seal, that actually do. If you make me guess, I'd say if the chip is big enough that at any...

A gasket sheet really shouldn't be any better than a gasket ring. The seal comes as the compression of the gasket forming a seal from pressure directly from the flange and nut. If there isn't enough pressure which would be the case for any part of the gasket sheet not under then flange and nut...

I've been through more modular marine overflows than I can count. Here's some general suggestions. 1. You should only need a bulkhead in two spots. In the tank (between bulkhead flange and tank) and one between the outside of tank and the external overflow box. Using a bulkhead in the external...

Unfortunately, I'm not able to attend, but I'm sure it'd be interesting to hear their take on antibiotics in the industry, both for home treatments and the usage of antibiotics for prophylactic treatment. Especially in distribution/wholesale and LFSes where it's known that they run low doses of...
