losing water

is it normal for a saltwater tank to lose water like it just evaporates, and the salt builds up on the top of the tank. i seam to have to add atleast 5 gallons every 3 weeks or so.

totally normal. i lose about a gallon per day. you should top off daily to keep the specific gravity at a constant level.

I hope you're topping off with fresh water; and doing it well before you need to add 5 gallons at a time.

adding freshwater RO/DI water to the tank as it evaporates. a jump in salinity up or down will cause a lot of stress. I top off 2 times a day when I get up and before I go to bed about 1 gallon a day.

"Top Off" just means to add fresh water (RO/DI,dechlorinated tap, or whatever your source) to make up for the evaporation. I think it is a job best done daily; just takes a few minutes. A full tank looks better too!

DO NOT add saltwater to top off. When you do this you are gradually increasing the salinity of your water. You want to add fresh RODI water. RODI stands for Reverse OsmosisDeionized. Basically, highly filtered water that is passed through a special membrane to remove all impurities. This is definitely one piece of equipment you should look into. In the long run it will save you a lot of money over buying premade saltwater from your local shop.

when was the last time you tested your salinity?
salt does not evaporate so adding more salt to the tank will only add to the salinity after so long it will not be able to support any life in there.
RO is reverse osmosis filtered water. It is a good investment if you are going to keep a large tank./

I Cant Remember The Last Time I Checked It. I Have No Idea What It Is At. How Does The Ro Thing Work? And How Much Do They Usually Cost?

KP with all due respect, and please take this advice in the manner it it intended. Go to your phone and take it off the hook, then walk to your refrigerator and get a cold can of your favorite beverage, open the can, put your feet up and get comfotable and then click on this thread. https://forums.saltwaterfish.com/t/264597/a-list-of-extremely-helpful-threads-for-all-hobbyists You can skip the first section about how to post, you already know that. Start with the beginning your tank section and read, read and read. Your brain will hurt, your nose may bleed, you will see stuff that you already know, and you will see stuff that you did not know, and did not know to ask about, Once you fel woozy, you will be fine. We all have done it and felt it.
In answer to your questions, and RO unit is a reverse Osmosis unit and is really a superfilter for your water. They run about $150. You can also buy RO water at your lfs or in jugs at the grocery store.

it can if setup with an auto-topoff module in general the basic models do not have this and needs to be added to the order and bought seperately.

Agree 1000%, we are not trying to offend, but some basic knowledge is needed here. Buy a book or two on keeping SW tanks. Three good ones to consider may be "Conscientious Marine Aquarist " , "Marine Aquarium Handbook " and "The Essential Guide to Keeping Saltwater Fish ". These materials are very helpful to those new to the hobby and nice to have for reference, even for the seasoned vets out there. Just my 2 cents

Here's my 2 cents---PLEASE do what these two guys have suggested; the questions you're asking are good ones. But; they cannot be adequately answered by a back and forth talk on this forum. Please do some basic reading, the link suggested by Scotts or the books in trippkid's post would be great places to start, and we'll be glad to help. In the mean time, if your tank is going downhill; get back A.S.A.P. Good luck and good reading!
