Keith, thank you for posting. I think I turned all of those HOB air driven filters into other things. Anytime I see a plastic container, I have to build something out of it.
This is one part of my workbench today. I just love plastic containers and I go to a plexiglass factory occasionally and buy the stuff by the pound.
I have my de-nitrate coil there which is running in a test tank, above that next to the blue tank that is my top off water is my DI chamber. Of course the black and yellow thing is the shrimp hatchery and the long white thing is the worm keeper.
The main part of my workbench has stuff on it still under construction and my garage workshop is for larger projects. Today that has boat parts on it.
I also keep a large assortment of parts, motors, relays, valves, switches, etc. You just have to have this stuff if you want to build things. You really don't want to run to a hardware store everythime you need something.
Everything in my house is automated and leak proof, as far as it can be.
I feel sorry for anyone who buys my house with the assortment of wires, tubes and ducts running all over the place. Everything is monitored with LEDs
(I just love those things) on my boat anytime something goes on like a bilge pump, bilge exhaust fan, fresh water pump or head pump, I have blinking, very bright LEDs on the dashboard informing me of the situation.
Under my tank and in my skimmer bucket is DIY leak or water detector switches that shut off the pumps if there is a leak.
This is why I don't sleep at night. There is a pad and pencil next to my bed to draw inventions or modifications on.
I can't turn off my mind and I don't want to :wildone:
My reef also has this horizontal algae trough but I have been re-designing
(only in my mind) to be much more efficient, nothing is stagnent and everything can always be improved, nothing is perfect but it is something I strive for.
In the second picture of my skimer you can see my boiler thermometer. The big round thing. The copper probe is in my tank sealed in an acrylic tube.
The 3rd picture is my evaporative chiller, That plexiglass box used to be my Wet Dry filter many years ago.I just cut it down a little for the chiller.
To the left of the chiller is the float switch from a commercial air conditioning unit on the roof of a Bldg, in Manhattan.
This has always been going on from my first tank. I am a DIYer at heart and I would never just buy something like a skimmer, it just could not happen.
Then you are at the mercy of some engineer, usually in some other country and they have no idea of your particular criteria. Besides that, they have to build the thing cost effective, I can build it myself, much cheaper while using much better materials.
