Hey all I am just wondering if the end result for canister filters and reactors are the same? Thanks

Ok so here is where i am literally.
So about a week ago i tested for electricity in my tank. I had and auto clamp tester with leads and a cheep analog tester. I was getting strange results and consulted RC and then Marc who reminded me of his article he did some time ago. http://www.reefaddicts.com/content.p...ay-Electricity Using his article as my guide i set out to test again and decided to get a tester similar to the one he used to help eliminate human ...

Ok so just a few quick questions as this is my first skimmer.

1. Are skimmers in general meant to always have the foam at the top of the neck or just when there is something to skim? For example when you clean green algae off your glass.
2. Does it matter how deep in the water they sit or is it just a matter of adjusting them to your desired skim rate?
3. Is it better to see large/med bubbles coming out or small bubbles like a frothy foam?

Here are some pics ...
