Leaking Tank

[nvmycj]

O.k.
Novice Questions Here...........:
1. I Keep Reading About Tanks That Leak. Where Are They Leaking From? The Corner Seals? Overflow Box? Is There A Way To Save Your Tank Once You Find A Leak?
2. How Much Lr And Ls Is Too Much For A Tank To Handle? What I Mean Is.....will The Bottom Of The Tank Fall Out Due To All That Weight? Is There Such A Thing As "too Much Lr?"
3. When You Buy Coral Attached To Lr, Do You Take Some Of Your Established Lr Out Of Your Tank? Kind Of An Even Trade, Or No?
Sorry About All These Questions, But The More I Research The More Question Pop Up.

1. The most probible area for a tank to leak is where it has silicone. If its left without water, the seel can crack, thus creating a leak.
2.I think too much live rock would be if your fish cant swim around. Remember, water is extremely heavy. So if you had 100lbs live rock in a 20 gallon, not much water would be able to fit in. The water is heavier than rock, so the more rock, you get accually less weight.
3. If you bought coral on a peice of LR, it probobly wouldent be too big, and more lr is always good. So unless your tank is REALLY packed with lr, then it would just be a bonus.

if you are worried about your LR damaging the bottom of your tank, you can also allways put some cheep plastic cutting boards, or other materials (you can search around, and find some other threads that make suggestions) to evenly distribute the weight of your LR, which keeps your rock from creating point pressure on your bottom tank glass. That and your substrate will cover it up and no one will ever know!

First, if you place live rock in you displace water (they weigh the exact same (actually)), but that's not the issue. The issue is that when nitrate or any other chemical is accumulated in the tank you have remove the bottom number of the reading. parts per million means mg of nitrate divided by the volume of water (in this case liters). So, add too much rock (I'll give an example of 2x more than another tank) you have doubled the concentration of ppm reading for the one tank compared to the other.
Second, when you add corals you do gain some rock, but unless you are maxed out already it doesn't really effect the tank.
Also, the bottom of the tanks are tempered (they are stronger than the rest of the tank). You can also run a plenum and that uses plastic eggcrate under the gravel, if that makes you feel better.
And finally the only place the tank can leak is through the seams (silicone closures). The other spots are not leaking they're called "broken"

O.K......
So in conclusion, the tank that's been collecting dust and used as a storage been in the LFS, would probably leak? Do the majority leaks come from the silicon around the overflow box? Once a leak is found, can you fix it? Thanks again for the informative replies!
