Fixing a leaking tank
 
I've gotten a large tank but one side is leaking. How do I fix the leak?

First of all I must make an assumption that the tank you speak of is the modern frameless all glass variety, with just a plastic (usually black) trim on top and bottom. Not the old style (hard to still find) with stainless steel framework and a slate bottom. If it is the new type without the ss frame, AND there is no visible crack, its not too hard to seal.
Obviously you must work with a completely dry tank, If possible trim away any excess silicone if it had been patched before,( the original sealant would be very neat and barely exposed since its mainly just between the glass edges).
Then using not just a waterproof silicone, but also one that is marked NON-TOXIC preferably one packaged specificaly for aquarium making, seal the entire offending joints using a popstick or similar to keep a neat profile. Next you must wait 48, to 72 hours for the sealant properly cure. After that the silicone should be rinsed off lightly before filling the tank with water to check your handiwork. Personally I would not use that first tankful of water but empty it and refill.
I hope this was helpful, and good luck.

Remember to use only 100% silicone that was made for aquarium use. Any other silicone with aditives will be toxic to tank inhabitants.

How much lighting do I need to raise my corals . I have a 62 gallon corner tank it's not insanly deep but it definately not shallow its maybe 22inches deep. gonna start with soft corals but I am eyeballing the stoney corals.
Once my tank is mature enough for the stony corals I do not want to change my light fixture unless I have to! Please advise.

Forget it go buy a new tank it's not worth the problem of it leaking again it happened to me I'm a pretty good caulker as I did it for a living 3 months later she leaked again. I heard even new tanks r only good for 7 years😍😍🐬🐳🐟

I used a hair dryer to dry all seams and GE makes silicone for aquariums it's type 1 they also make type 2 not for aquariums. Good luck my new 55 was 98$ no problem 😆😎🐠🐳🐟
