Based on the data, my plan of using a saline solution to get rid of the slugs in my hot tub was ineffective. I thought that the salt would have forced the slugs out because it was said to barely burn their skin and cause them to want out. I also assumed that if this was the case, then as long as there was solution on the interior of the hot tub, then wherever the slugs were coming in from would also be covered in the solution; this would ultimately act as a barrier to keep them from coming back. However, throughout the week, there was hardly a reduction in slugs. On the first night, there was no change, still 7 slugs. Then, the next day, not only did the solution not cause slugs to leave, but another showed up! As the week went on, though, the number of slugs did slowly decrease. The solution seemed to be somewhat effective, but because the difference between day 1 and day 7 was only 3 slugs less, I would not count this as a successful experiment. The data is valid because I did not change any variables such as solution or amounts of spritzing. Also, it was reliable because I essentially did 7 trials, one each day. I think that the saline solution is a good idea still, but in the future I would include more salt in it, to have more of an effect on the slugs. This experiment is useful because for future references, I have a better idea of how to remove the slugs from my hot tub in case we ever try to get it fixed. We don't want to be swimming with slugs!
