So, I went off to the airport last night at 11pm for my last shipment coming in.
When I got home, I started floating the corals.
I had a bit of time to kill while acclimatizing so I thought that I would deal with a leak with one of my tanks. It had been leaking at the bulkhead seal between the maintank and the sump below.
So, when I started to attemptto tighten it up abit when I hear a crack and drip drip drip.
I look up and see that I have managed to crack the glass between the downspout and the return hole. NOT COOL.
Being that there is the stand under most of the tank that extends everywhere except the very corner where the holes are for the bulkheads.
So I spent the next hour emptying the tank into my other tanks and yea..again not impressed. All that I have left in the tank is the sand bed and about 3 inches of water. I didn't empty it completely cause it was 3 in the morning and I needed to be up in a couple of hours for work.
My question is this.
if the crack is not that big, IE just around the holes, is it safe to try to somehow repair this?
it is a rounded corner tank that is shaped sorta like a 45 degree piece of pie. the holes being in the tip of the shape. If anyone knows the corner tanks that aquagiant sells, this is the 44 gallon one.
there is a wall that separates the main area from the area where the holes are. I am not sure if the crack extends beyond that wall. If it does, I think I am hooped.
If it doesn't any suggestions and how to fix this? would you attempt to fix this? or is it too risky?
My thought were to maybe cut a piece of plexy and glue it down over the cracked area and redrill the holes for the bulkhead?
the tank is like 6 months old and I just the first fish into it last week.
On another note, has anyone had any issues with aquagiant tanks? is there any warranty? as far as I am concerned the tank should not have cracked.
I think that I am going to call them and see if they will replace just the tank.
Any advice would be appreciated.
thanks

I wouldn't risk a repair job, it's just not worth it. (water damage sucks)

i agree a new tank is a lot cheeper than a exploded tank

How tight should the bulkheads be.

i am obviously not the one to ask about how tight they should be..lol..

Anyways, I just called aquagiant and they told me to bring it in.
they said if they can't fix it, then they will replace it.
NOW THAT IS CUSTOMER SERVICE.
In an age where customer service has gone down the drain and the customer is no longer always right, Aquagiant...YOU ROCK.

Common mistake I'm afraid... don't overtighten bulkheads.

I've broken a few glass panels too, thinking "just one more quarter turn."

Usually this is more of a problem with 1/4" glass or less. If you can break 1/2" glass then you're making the bulkhead WAY too tight! ;)

Basically if "slightly beyond finger tight" does not give you a 100% seal then something is wrong. Things to watch out for:
- the seal for the bulkhead usually has a little "ridge" on it -- this should face the glass
- it should be on the inside of the tank
- maybe there is a particle or abrasion/burr on one of the surfaces preventing a seal.

Failing all that .. putting a little smear of silicone around the threading or around the bulkhead side sometimes is needed (i.e., bottom of the tank and there is static pressure on the seal and so on). But in general it should not be necessary to silicone a bulkhead (I've done it and usually do it for added peace of mind, but the theory is that it's not "necessary").

I once broke a tank that I was drilling that had livestock in it. We had lowered the waterline so to install an overflow box. I had to drill on the vertical which is always a challenge but I had done so many times before. The trick though is to really, really, really back off on the pressure towards the end and .. well I didn't back off enough. I punched through, fell a little forward and.. crack.

Since this was a live tank emptying it was not an option. But the good news was that since it was where an overflow box was going to be installed, we were able to patch it up with some scrap glass, siliconed in place. And since it was an inwall tank the fact that it looked like butt didn't matter since it was a hidden surface. Anyhow moral of my little tangential story is that it IS possible to patch over a crack. In fact I have at least two patches in my sump for my 75g (again, overtightening bulkheads). An inconvenience for the time that the silicone is curing but only for a day or two.

It's of course better to NOT break the glass in the first place, but in general it is possible to fix these sorts of things. Just recognize though that it's not pretty. :lol:

Good deal. You're right on about customer service these days.

I was just going to chime in that it is not worth trying to work around a cracked pane. Once cracked it is significantly weaker. Even if you have to buy a new tank, it will be MUCH cheaper than replacing livestock, and repairing water damage.

I think my All-Glass instructions say to just hand snug the bulkheads with the supplied wrench (it has no real arm length on it). If it is already fairly snug and still leaking then it's probably the fitting and/or the rubber seal that is hooped.
