Snorkeler's Cube

Got some time to post, will continue my thought process from the last blog post.

I concluded a few things from my experience in these 2.5 years:

1. I should underfeed my fish. First because I probably have a tendency to overfeed, second because they don't get easy food in the wild. Come on, "real" fish have a hard life! They swim a lot, compete a lot for food and don't get that much prey every day.
2. I should finger feed my fish. A tank as small as mine (DT=180L/48G) doesn't

It has been a while since I last posted, mostly due to lack of time due to work overload.

Which obviously meant I also had little time to take care of the tank, and it went backwards.

My 4 mithrax crabs gradually died (of age I believe), leaving me without valonia eaters, which isn't good. One of the mithrax crabs (the hardiest of them, last to die) apparently was of a different species and I caught him eating my zoa colony. Moved him to the sump a month ago, and I ...

Time is short, so much to do and so little time.... once again I post about something I did almost a month ago. I almost skipped this one, but, blogs are about sharing experience and I think the pictures will be useful to teach people what NOT to do .

Compĺeted my annual maintenance cleanup... and concluded annual is too long a period to do it .

Before you see the pictures please mind that my refugium is lighted by a non direction compact fluorescent light, ...

Finally, after almost a year between planning, prototyping, building and coding, my DIY LED fixture came to life. On Sept 6th the woodworking shop, LD Marcenaria delivered the new hood (they are very good, super recommend them to anyone living in São Paulo). It looked good, had dimensions according to the Google Sketch I had drawn, seems strong, etc.

Installation was way longer than just swapping the old hood for the new one because I had to redo the Aluminum structure of the ...

First day of vacations, not feeling well, spent most of the day either at the bathroom or sleeping.... at night I was feeling a little better, so I decided to work on the Arduino sketch, try to finalize v1.0 of it. Testing was still needed, so I proceeded with the test generating sample light curves for the various day types. By day type I mean "clear day", "cloudy day of various intensities", "thunderstorm day", each defined by an Okta number from 0 to 8.
