Hi Arrowhead
Whatever else you do, you
MUST learn how to use that siphon. If you don't do proper water changes and vacuum the gravel, fish wastes and uneaten food will build up and at some time or other, your fish will get sick.
Using a siphon is something that takes practice to learn to use, but once you figure out how to get it started, it will become as easy as can be. A lot of people have trouble figuring it out too, so you are not the only one. I suggest you fill the kitchen sink and put a bucket on the floor to experiment with it.
I'll explain how it works and perhaps some of the other members can add suggestions too. First, a siphon works on gravity. This means that once the water is in the hose, if the bottom end is lower than the top end, the water will flow downhill. If the top (big end) stays under the water the whole time, once it starts flowing out the bottom, the suction will pull the tank water out along with it. If you let air get into the hose it will break the suction and the flow will stop.
In the sink, try pushing the entire hose underwater until it is full. Then, while keeping the big end under the water, put your finger over the small end to seal it and carry it down to the bucket. When you release your finger, the siphon should start.
If your siphon is small, like 6 feet or so, you can even start it this way in the tank, but once you practice for awhile, you will see that the idea is to just get the water flowing downhill while keeping the big end under the water. You will eventually be able to fill the hose by scooping up water, raising the hose to get it moving down, and quickly getting the top into the water so the suction can continue before air gets in the line.
Whatever you do, it's of critical importance that you learn to use it.
