The Minnows are All Right

Fathead Minnow


I wanted to snap a picture of my progress with the greenhouse, but the camera needs batteries. So well talk minnows instead.

The fathead minnow is a cool little fish. They are great for live bait, and theyre hardy. An eHow article on fathead minnows explains:

"It can tolerate low oxygen levels, muddy water and a wide range of pH levels, even those inhospitable to other fish. Due to its hardiness and ease of breeding, the fathead minnow is the preferred fish for toxicity testing under U.S. Environmental Protection Agency guidelines."

Most of the minnows I bought last month are still with us. Its fun to see them zipping around the tank, schooling together.

The bluegill and redear that have survived are a stolid bunch. They are slow and stealthy, hiding in the recesses of the tank. I wish the tank was lighter, because its quite hard to see these larger fishes, lurking as they do in the depths of the tank.

Sunday the low was a nippy 29 degrees F. But as I look at the forecast and averages from here out, it looks like freezing temperatures have departed the pattern until next fall. Im excited to see how the fish do as it starts to be consistently warmer!

The gangs all here

Today I added the remaining 22 fish into the 800 gallon aquaponic fish tank.  They were very happy to see their old friends and a good time was had by all.

I built a light fixture today with 16 CFL bulbs in a straight line 8 feet long.   Its a lot of light, but I may need two.

Costco has a good price on 23W 1600 lumen CFLs (about $8.00), but there were some rebates that knocked another $2.00 off the price.  So each box of 4 costs $5.99 right now.    I was going to use T5 bulbs, but I saw that, and did the math.
Im waiting for a response from the manufacture for more information about the light spectrum.  All I have been able to find so far is that they are "Full Spectrum".  Im hoping this will work for me, if not Costco will take them back.

Ill post a picture of my finished grow lamp after its painted, and the specs if I hear back from Feit Electric.

Here are the specs on the CFLs that Devin Duhaime is using very successfully.

Philips 41409-4 - 26 Watt - CFL
