Filter Confusion
Hey everyone,

Just got a little 10 gallon that is filled with sand and the saltwater also with a pump circulater. I've been waiting for the sand to settle down but as it starts to do so the pump cocks down and blows it everywhere so i shut it down ti'll the sand settles. I heard i really dont need a filter for this tank. I just need to do about 20% water change weekly about. maybe less. My plans for this tank was just to take a friends shrimp off his hands becaues he was going to flush it and i couldnt let him. I am eventually going to go some good lights so i can have a little coral in there. I will also have a couple other fish in there too. I have a 10 gallon filter for it when i had freshwater running in it so I heard all i really need to do is get a new filter cartridge and clean the filter out with vinegar and im good. The salwater will form its own sort of thing like freshwater. I'm learning as I go along so ANY suggestions are welcomed :D

What ype of "sand". No play sand please. If so remove it. You want aragonite, sugarfine, or south down. Don't get crushed coral either as it is a waste trap. Will make your water sour. Well as long as you tend to the filter it won't hurt running it on a small tank. If you plan to go "natural" you will need lot's of quality porous live rock. About 15lbs would be good. I have a small filter on our 7g nano to provide currents for the tank. It gets cleaned weekly. It isn't for biological filtration, only mech. If you let the wastes sit in it to long they break down and repollute the tank. A great idea for larger HOT filters is to cut some of the veins off the impeller to slow it down. Add a layer of mud and aragonite to the bottom of it and add cheato macroalgae. This makes a mini fuge on the tank providing for nice filtration and a place for microfauna to grow. It can take as long as a week for the substrate to settle out. I turn off my pumps but another person once told me that keeping them on will settle a tank faster. I couldn't see why but he told me it causes the particles to bind into heavier pieces. After 3 days I decided to turn off the pumps until it settled.

The sand is actual saltwater tank sand. I didnt just go to home depot or something and buy the sand ( play ). So I know im good there. I have current already a pretty decent pump. The suction isnt good to the side of the glass so it would just dangle and point down and blow the sand into a hill and cause even MORE cloudyness...I will have at least a nice chunk of live rock in there I'm not sure of the plbs its not shaped like a rock either. Its just a branchy looking thing that my buddy is giving to me for starter...So do you think I will be okay w/ out the filter? Doing weekly maintenance?

Sounds like Tonga branch rock. Stuff isn't really that good for biological as it is pretty smooth. I'd still think about running the little filter as it will also help break up the surface of the water. This will leave an open spot for gas exchange. Salt tanks do a really good job of floating wastes due the increased density of the water. A lot of gunk quickly masks the surface of the water and that falling water coming back from the filter will help keep an area open. You might need a smaller maxijet or you migh find it better to put it lower in the tank and point up towards the other corner to help prevent it crashing back to the substrate. One it is all settled in I'd suspect you could up the flow again without the cloudyness.
