Okay. So, you’ve cleaned out your tank and made sure that there is no more dust, dirt, grime, spider webs, etc. in your tank. It’s time to do a leak check! This isn’t something that takes too long, and it will save you a whole lot of stress and disappointment later on. Personally, I would do this with any tank, new or used. A new tank shouldn’t leak. It came with a warranty from your LFS right? Well, I’ll let you figure out how upset you would be if you put water in your new tank, went to bed, and woke up the next morning with a wet carpet and little to no water left in your aquarium.
So, first you need to find a location to perform this test. This should obviously be a place that is easily cleaned and mopped up if the tank does have a leak. Maybe this is a spare bathtub, or your basement, or your kitchen with a tarp under the tank. Find a good spot, and fill the tank up with water! RO/DI water is again preferred. After all, you don’t want all of that chlorine and minerals from your tap water to coat the inside walls of your tank. However, if tap water is all you have, it should end up being okay. You can go ahead and perform your leak test while your RO unit is being shipped to your house. That’s it! Just leave the tank filled with water for several hours. Leaving it full for a full day or two might be best.
If there are no leaks in your tank, start siphoning the water back out of the tank and down a drain. Don’t try to pick the tank up when its full because you risk cracking the tank. Remember, water weighs a lot! Once the water is out, you should have a clean, leak free tank that you can put on your tank stand!
If there is a leak in your new tank try to find where that leak is and bring it back to your LFS. If there is a leak in your older, used tank you will have to find the source of the leak and try to fix it before setting the tank up.
