More Progress

November 10, 2020

I finished the Artificial Reefs section of the website, probably the second-largest piece after Dive Sites. These two are also the most complicated sections, since they involve geography and spatial relations. Again, no more clickable charts. That would be a huge job, and I would have to get awfully bored to want to tackle it. WordPress is doing a very nice job of handling all the relationships between pages and subjects.

Using WordPress taxonomies, a site no longer needs to 'belong' to a particular chart, it can belong to several at once. That was something that had to be hand-coded before. There's an old programming adage: "All problems in computer science can be solved by another level of indirection." Look up that quote if you are interested.

WordPress tells me that Artificial Reefs worked out to 235 pages, while Dive Sites is 425.

Aquarium Guide - Filtration

The main purpose of a filter is to circulate the water. This leads to better aeration and higher oxygen levels for both the fish and the critical bacteria which decompose the fish wastes. The more obvious aesthetic effect of filtration is the mechanical removal of particles in the water, but this is of much less importance. Since most aquaria are stocked far more heavily than natural conditions, constant effective filtration and circulation are essential. On large tanks ( 55 gallons or more ), consider using two smaller filters in place of one large one, and place them at opposite ends of the tank for maximum circulatory effect.
