My burkert solenoid arrived today that I purchased from Very excited as now I can prepare the setup for fish. Unfortunately, my regulator didn't have the proper fittings for the device, so I had to make a trip to home depot. Picked up the Watts A-738 Pipe Hex Bushing 1/4" MIP x 1/8" FIP to hook up directly to the regulator. I also got the Watts A-715 Brass pipe nipple 1/8" MIP x Close. Spent about $3.65 total. Unfortunately, Home Depot did not carry a swagelock male 1/8" to metering valve fitting to connect the solenoid to the needle valve. But when I got home I was able to salvage this fitting from the original setup that I had attached to the regulator. I was lucky to discover the following link to a post here on TPT that diagram said pieces above. It's important to note that the 1/4" to 1/8" fitting that connects the regulator connects at P on the Solenoid. You can better see in the picture what I'm talking about.

Plugged the solenoid and light into a power strip that is connected to a wall timer. This device works like a charm and so far no leaks. Before I received this solenoid, I realized that I had been experiencing a lot of additional co2 being diffused into the aquarium after I turned the co2 tank off. In fact, after shutting the tank off, co2 would continue to diffuse for nearly 3 hours. Which meant bad news if you were a fish or invertebrate. I think it would be safe to deduce that the the additional co2 diffusing into the aquarium after the tank was shut off was a bleed off from the co2 stored in the regulator. Now, however, with the solenoid, once the valve closes, the co2 diffusing into the tank ceases almost immediately. Once I can stabilize my co2 levels I think it'll be safe to add the white clouds. I added an otocinclus today. I'm keeping my fingers crossed that he will make a good dent in the developing diatoms. Kept the light off for a while when I first introduced the fish to lower its stress level. He seems to have adapted very well to the new environment. Nitrates were zero this morning. Did a 50% water change before adding the otto. Didn't add any additional nitrogen. I will measure tomorrow morning to see what affect that oto is having on the levels. Probably not that much of a change at first. But once the white clouds get in there I'm sure the nitrate level will change. All in all, two nice additions to the tank today.
