Diving with Bull Sharks

I’ve wanted to do this bull shark dive in Playa del Carmen for a while now. I wasn’t eligible in the past because not only do they want you to be certified, but they prefer you have at least 30 logged dives so the dive company would be more confident that you would not panic and screw up the dive for everyone. It’s also an 80’ deep dive which is on the deep end for a typical recreational diver. If you’re certified in diving, I highly recommend the bull shark dive. It was a lot more fun than I thought it would be and I would probably do it again in the future. It was a great trip down to Mexico and I’m already looking forward to going back.

Is Bigger Better When it Comes to a Protein Skimmer?

Bigger is better when it comes to a protein skimmer, right? Not necessarily. Using a high capacity protein skimmer on a smaller tank can be problematic. Why? Well, using an oversized skimmer will result in an inconsistent performance. Let me explain. To perform optimally a skimmer should be working all the time. An oversized skimmer will tend to skim well for a few days then slow down once all of the organics have been skimmed out. Once the organics build up again the skimmer will spring back into action, and thus perform inconsistently. How do you know whether you have the right size skimmer for the tank? I was always under the assumption that sizing should be based on total gallons in a system so I figured
