Marineland 300DD Bottom Support
I've seen a couple Marineland 300DD tanks for sale lately, and I really really like the dimensions. However, they have a nasty reputation for blowing the front bottom silicone joint.
My question is this: If I got a piece of glass cut and siliconed it to the front, along the bottom, and to the back of the tank (inside the tank and later it would be covered in sand), would this provide any meaningful structural support? How thick do you think it would need to be to provide meaningful support? I contacted customer support and was told the lifetime warranty to replace the tank only applies to the original owner, so I'm not worried about voiding that. Thoughts would be appreciated!

If you google glasscages or coasttocoast tanks you will see that they do internal eurobracing along the bottom seams. I think it's a very good idea. I would think that you'd need to remove the internal fillet of silicone in order to get good adhesion.

Interesting. I looked at one this evening. I can get the tank and stand for cheap enough I'm far more interested than I should be. I'll have to look into this internal bracing.

Get a well made stand and you wont have issues.
You can add bracing but that involves cutting out the old silicon and resealing the tank with the new pieces. Ive had my 300DD on a custom plywood stand for the past 10 years with zero issues, and I have honestly never heard of this issue with the 300DD's before and I know plenty of people who own them. |

I've got the 300DD and love it. I just made sure the tank is flush with the stand in all places. The stand is a beast, true, and level. I bought it used as well and got a great deal. Was a little nervous at first due to all the stories about blown seams but it's been over a year and now I never think about it.

Are you using the Marineland stand?

With regards to the OP I personally would pass on a 300DD especially used. On the other hand if you want to replace it the advise removing, cleaning, bottom euro brace, and reseal is probably the safest. Good luck either way - really nice dimensions on the tank otherwise.
