Watching Grass Grow

Who thought it could be such a joyful thing? Lots of new Halophila growth. The larger grasses are not doing so well but that is to be expected. Hopefully they will spring back in a few weeks time.

Another 7% water change tonight. Also cleaned the fine micron return socks out in the drained water.

Some sections of the grasses needed a little replanting. A couple of Halophila rhizomes – which still had new growth on them even though they were taking a jaunt into the blue – and a couple of Cymodocea stems had hmmm… I would say aerated but that’s for the land lubbers… super benthic (hah!) roots.

I have also been fiddling with the videocam settings. It is a Sanyo VPC CA9EX, submersible to 5 feet (so snorkeling only). The compromise is that the video quality for the price wasn’t as good as some. Still, lots of fiddling later I have made some dramatic steps forward.

The most important change is setting the ISO to the lowest setting of 50. This removed almost all of the really annoying graininess I was seeing. Then I set the Exposure to Shutter with a speed of 1/100 of a second. This lets the f stop vary according to available light. I also set White Balance to Auto. I went with a lot of manual settings but the ability to move from high light to low when zooming was really a necessity and you can only easily do that on a video-cam with one of the exposure settings controlled by the camera.

Oh, and finally, hope you like the new site header background!
