The air delivery should be above the water to prevent back siphon in the case of a power failure. If I were doing this in a 'finished' display room I would put the pipe just at the highest tank and use check valves.
On your recommendation, I constructed a small, 3/4" PVC, closed loop system with a larger valve to bleed off unused air in order to avoid excessive back pressure for my Jehmco LPH26. Do you use a check on your system and if so what kind? Most of the check valves reduce the airflow to 1/2" or smaller. While I use individual check valves on all my airlines, I am unable to mount the pump higher than my tanks. Should I use a check valve or are the individual valves sufficient?
"small bubbles from air stones make filters run more efficiently" can you elaborate on that? or did you just mean that newer sponge filters make smaller bubbles, and should be switched out when that changes.
+maileen420 When there are a lot of small bubbles filling the lift tube, the combined surface area of all the bubbles together push more water than the relatively small surface area of a few large bubbles.
Overall cost varies depending upon the size of the space and the how much automation you want to install. The room in the video you comment is attached to cost me about $5000. My current fish room would be less expensive (many fewer tanks)
thanks for this! even 8 years later still relevant
A lot of great hard to find Info in this video. Thanks!
This is so helpful, thank you!
Installed mine last night :) best investment in the fish room yet.
Good video, thanks for posting!
Great info!

Is the needle valve thread type standard and is the thread tapping tool also standard? If not what type of tap did you use?
Different valves have different threads. Buy them from Jehmco and they can sell you the right tap to match each type of valve.
Thanks the information is great but where can I get the Valve and tap to buy

+Ted Judy got it, the whole "air stone" thing threw me off, thanks!
why does the tubing need to be high in the room? wouldn't it look better if is was hidden?
What brand and model is your linear piston air pump?
I got it at jehmco.com. Not sure of the brand. It is the only linear piston brand Jehmco sells.
I want to have a fish room when I'm older, do you have an approximate budget I will need to obtain to make this?
