I am subbed to both of them! I was just wondering ways to get more views, because I made a video of my tank, it took ages to compile all different clips, add music and transitions an It only got 24 views. don't laugh.
I look primarily for "how to's". Build a sump start to finish and don't leave out anything and you will get hits. Make sure to use appropriate key words and titles. Build a rock wall. Build your plumbing. All you typically see is before and after BS and none of the most important in-between parts. You do that and your videos will be gold.
I always look for comparisons of equipment and find that difficult to find. I would imagine most people are only going to review what they already own, but a video showing the difference between two different skimmers or two different pumps, etc. would be very helpful to me and others I'm sure. I think it would be much nicer to have multiple brands in one video for size, noise and performance comparisons. Probably sounds dumb to some, but just my 2 cents.
review WHATEVER you have, and everything, everything down to fish foods and sand or salt. Also, i think its neat when they have a voiceover, it makes it sound more professional because you can read a script while you talk into the mic. Always repeat things in reviews, to make sure people heard you. I do youtube reviews for another hobby of mine and im always sending emails out to small businesses asking for a small sponsorship, just to get more videos out and help them out too.
