Logging any dive is important, that said even though you log it, that doesn't mean it actually counts as a dive.
Each agency has their own requirements as to what counts as a dive or not. NAUI, for one, does not count any of these dives as actual dives - that said there are a few notable exceptions to this where NAUI will, and does allow for ONE LOGGED dive in confined water - most notable is the Disney dive which you can in fact log and does count for NAUI.
Second point...any time you breathe SCUBA - it is a dive. Diving in an Aquarium environment falls under OSHA and NOAA and it's considered "commercial diving" believe it or not. So, follow those rules for logging a dive. The 20' for 20min is a recreational agency requirement - NOT a OSHA/NOAA regulation requirement. You log everything, even 2 minutes to fit their logging requirements - it's a completely different standard.
Logging a dive proves experience for the purpose of advancing training and fulfilling dive requirements for future dives. Just because you log a dive, any dive, doesn't mean it actually "counts" as a dive for this purpose. It does show you're active, usually indicates a higher degree of comfort and skill in the water and I strongly encourage you to actually record any AQ dive - just separately from your recreational dive log.
The guy's give me all kinds of grief at the shop for logging my AQ dives but here's the bottom line. I get to dive year round, I get to dive frequently and my skills and comfort are 100x better because of it.
Go have fun, go blow some bubbles and log it - just keep it separate.
