New 300 Gallon Tank, cosmetic damages... your thoughts please!

  • We are currently upgrading MFK. thanks! -neo
I too wouldn't be concerned about the chip. However my concern would be lack of upper and lower trim. By the looks of the tank it"s an older design and surely had trim at one point. I had a 300 gallon with a crack in the lower trim I resealed 4 times and never could get it to hold water. 3 times i reselaed 4th time I paid to have it resealed, still leaked. The decoration around the canopy has a reptile, which my best guess is the tank has not been used for fish in awhile. (just a guess). I would rebuild the canopy scrap the stand and rebuild a new one. Add upper and lower trim, and check the seals very closely. Just my 2 cents

Ill take this into consideration, going to fill it with water and let set for 24-72 hours to see if it holds with no leaks... I'd rather not build a stand myself since I have NO knowledge on any carpentry, let alone crafting something solid enough to hold 2000-3000lbs...
 
Oh yeah... that trim not being there may be an issue.

I would definitely beef up the stand. I bought a stand made for a 240, and I still beefed it up.. can't ever be too safe.
 
Someone school me as to the purpose of the trim, I always thought it was a cosmetic issue, as I see "rimless" tanks also available for purchase. Does the trim serve as a reinforcement along where the joints/corners are glued together?

Beefing up the stand doesnt seem like a bad idea. I have a feeling this one was home made, and it couldnt hurt to do so. Ill have to get some carpenter friends to take a look, or start a new post here and see if any local guys would mind helping with this DIY project.. which then, doesnt become DIY anymore.. more like, Do It with Others, and I would gladly pay!
 
From my understanding, rimless tanks are made differently than tanks that do not have rims. I do know that if the top of the tank doesn't have trim, then it doesn't have the center brace, which for a tank that large is needed or it will blow out. I know that with a tank on the bottom rim, the tank is only supported on the 4 corners of the tank, and the bottom pane is not directly on the stand.

Beefing up that stand is not going to be hard at all.
 
Looks like a nice project for you. Other than the center brace issue, I would beef up that stand as well. Nothing wrong with a diy wood stand but you just never know. Personally I prefer steel stands for bigger tanks, but theres no reason that stand cant be made more secure.

Interesting this tank doesn't have trim? I didn't even notice that in the pictures. I had to go back and look at them again. Also interesting that this tank has been running fine with out the trim and now all of a sudden the tank needs trim? I just think that's odd? Is there a point like 5 years down the road or 10 years of running a tank fine without trim then the tank has to have trim or it will "blow out". I wonder if there's a thread about the age of tanks and trim requirements. Also same goes with the stand. Does the wood age significantly enough over the years where it wont support the weight after 10+ years? 5+ years? My 450 is on a particle board stand, it's gota be 10+ years old. That's not even real wood!
Dang this fish tank stuff is so confusing...............

its not odd if the tank was used as a reptile tank with no water as suggested.

its a huge tank, but my concern would be this:

I have been in the hobby for over 25 years and have had older style tanks with no trim, although they were not that big (90g, 65g etc).

the thing is, 90g tanks with no braces were made with 1/2" glass back in the early 90's.

my first thought was from the tank pics, it looks as though 1/2" glass was used, which would be okay if the tank was braced/eurobraced.

however, its not. back before they used braces, tanks that size would use 3/4" thick glass.

I would be weary of the tank as it stands. for a braceless tank, you always get some degree of bowing. tanks back then were designed with this in mind. if the silicone is older and has been allowed to dry out, that normal degree of bowing could cause leaks/or even a burst seam.

I would reseal the tank and add bracing for sure.

good luck with your huge tank! so envious! congrats!
