The filter was in storage for about 4 years, I had an indoor cat for that amount of time (she died about a year and a half ago), I'm tempted to say we must not have stored it correctly and it got messed up...? I don't think I had this many problems with it before, so....
At the moment I have a betta, a guppy, and a shrimp in my tank. Going to get more in the next week or too. All of the fish I have ever had thrive in our water. The build up is on the inside of the tank, there is no build up on the outside. I have tried scrubbing it off, that didn't really work. It's winter time here right now, or else I would just give the tank a total cleaning, and use vinegar on the minerals. I have a hard time toping the water off in the winter as it is, since our house is cold, I can't just fill jugs with water to come up to room temp because it wouldn't get warm enough, and I can't just run warm water because our warm side is hooked up to a water softener. We always have to fill a pot up and warm it up to the right temp on the stove.
Anyway, I feel like I've done more complaining than anything else on here so far, sorry about that
Thanks for all the help! I'll go check out those filters now

If the flow is not even then I would definitely suspect that something is broken or needs maintance. With the fish you have I wouldn't worry about the water hardness too much for their sake, shrimp at least very much like some hardness. Depending on how your water softner runs, you might be actually able to use the water as some softners are just basically RO systems. But if you use the softened water you would either need to add in some minerals back into the water in form of product or mix in some of the hard water. But again for the fish you have I would not go through that hassle.

I reaaallly want to have fish (we've had them in the past) but I don't know what kind to get. I'm happy with freshwater, cold water snf tropical fish. what are really pretty fish I can own that I can get in a pet store?
I have a 14 gallon tank
Bettas are pretty easy and very commonly available. For 14 gal small school of schooling fish is also possibility. Some of the smaller gourami species might also be an option, though some of them are bit picky about water parameters to really do well. Endlers and guppies could maybe work, but I would only recommend small group of males so that you don't find yourself with more fish than your tank can handle (endlers and guppies are known to breed very easily and quickly).
If you feel totally lost on what fish to get I would really suggest going into your local fish store, or pet store if you don't have fish specific one on your area, and see what they have in stock and if something catches your eye there. Then before you buy the fish, you go home and do research on the species you were interested in to see can you keep them in 14 gal and generally what is recommended.

Many stores are also willing to order specific fish for you, if they have them on their stockist lists etc., in case you come across a species you really want when researching but your store doesn't have them at hand when you visit.
Though bit of warning not all fish show their best colors or normal behavior in store conditions, so keep that in mind when looking at fish in stores.
