Tank Entry

... but the refugium is still lit up, it's easy to grab my Nikon and get a few more pictures for the night.

Feather caulerpa fills the refugium from end to end.

These sponges are growing on the back wall, so I moved some plants out of the way to inspect them. I spy some red feather dusters, lots of spirorbid worms, and some amphipods scurrying around.

Every three months, I refill the poly tank to the top with RO/DI water. This upright container is rated at 265g, and I have a small float installed to stop filling it at 250g. This provides enough room to add salt to the water.

For the past three years, I've used Sybon Reef Blend salt. It takes two cases of salt to mix up 250g at 1.026sg, so I got four cases of Fritz salt last year and am finally getting around to using it. Right before the cold front hit my area on Sunday, I ...

I got a 10' package of "1.5 inch Flat Discharge Hose" for $10, and as I walked to the car I spotted a brand new black zip tie in the parking lot perfect for this project.

The reason I use this tubing ...

I mentioned that I expected more shrimp several days ago, but when I looked under her hood so-to-speak, they weren't ready yet. Tonight there was no doubt.

I hoped to capture the release on video, but she refused to cooperate if any light was on. So as soon as the event occurred, all flow as halted, the Azurelite was placed over the corner of the tank, and I shot these with my 105mm Macro lens on the full set of extension tubes. I used a ...
