The skimmer is repaired and the bracket is re-designed with stainless steel so it should last forever. The skimmer didn't break, I broke it trying to remove a hose that had turned to glass over the years. One of the improvements is that the venturi valve is connected with a union so I can remove...

The thing was due for some maintenance anyway. This was galvanized steel and is the bracket that was under the skimmer and supported it's weight. I am replacing it with stainless steel.

OMG, what am I going to do? I am beside myself. (a few minutes ago I was two feet to the right) ::) I was designing a new venturi valve for my home made 5' skimmer which is, I don't really know, maybe 15 years old, and you know how those large vinyl hoses get in that time. Nice and brittle...

I did a test today and turned off my solar panels on my roof. Today is a light electricity day because there is no AC on or heat. According to my power usage meter (pictured) today I am spending 7 cents an hour for electricity. Not very much. I turned off the solar array and the price jumped up...

Dam, I wish I knew that 39 years ago when I put mine in. ::)

My amphipods keep copepods as pets but you can order them by truck

I collect amphipods in 5 gallon buckets like this. How is that for a pile?

I am fairly sure it would destroy any water based animal. I doubt it would do anything to crabs and snails which don't tend to fall apart as easily. I can touch the probe to a hermit crab and he does not even seem to notice anything

A friend of mine owns a large LFS and his reefs are loaded with mojanos so I made the mistake of telling him that I built this mojano zapper. He had to try it so I brought it there today and he loves the thing. He destroyed about 75 mojanos in about 15 minutes. And in his tank they are huge...

I souldn't put this picture on here, but here they are in a "friendlier" pose

I have a couple of old hermits that are spawning. I don't remember when I got them but it is at least 12 years or longer ago. The male in the foreground has her pushed up against that bubble coral. He is pushing her so hard that he is lifting her [I]and[I] the 8" bubble coral. I am surprised...

A friend of mine owns a LFS near my home and his tanks are loaded with mojanos. Very large ones, so I am going to try to go there today and test the device on larger mojanos. I may need to bring a larger transformer to generate more power for these suckers but it will be a good test.

Until the anemone is all white and pasty looking, about 8 seconds.

It would not generate any heat underwater using 300 miliamps. I believe it is the gas that is killing them. In Nam we used grenades to kill the animals before we swam

Actually, it does. I have found that in a day or two you may find a tentacle still waving so I zap it again. It's hard to tell when you are using it because the mojano turns into a styrofoam looking thing. The white stuff falls off and then if you see some movement, you do it again. It's real...

All fish tanks were made like that in the early 60s. I had a bunch of them and they were not too cheap. The stainless steel ones are the new ones, before that the corners were black painted iron. My first salt tanks were that type and I had to paint the steel all the time but it did not help...

Yes it does, thats why I try to make good use out of my garbage cans. I still have canvases from two boats ago which was about 15 years ago.

Just like in the picture. The black thing is a piece of graphite from a large pencil and the needle is a needle. Connect one to positive and one to negative on a 24 VDC power supply and if the graphite bubbles, reverse the polarity. It's simple
