yeah your fine. just make sure that if the collection cup gets full over night its not going to make a major mess on your floor. Skimmers have a break in period and this is normal. Bubbles in the water is normal as well. after a few weeks this should be reduced a lot. It might even go away all together. as mentioned keep us in tune as to what its doing, but id give it longer then 24 hours because you wont see much difference.
