Hi GR, I don't know how much pressure loss I get due to bents and from wye fitting. But I can tell for sure that the barracuda pump as what Sparss says is too strong for my return and for what I intended to use it for. I only have two 3/4 seaswirls installed yet, but 2 more additional 3/4 will be installeld at the middle of next week. I have to trottle several valves just to slow down the pump.
Right, I was able to fire up the external pump last night. Found a few spots were water were leaking. All the leaks are coming from those threaded fittings. I managed to fixed a few of them but there are 3 more spots I need to fix for water leakage.
The barracuda doesn't seem to be quite. I hear vibrations and hamming. It was too loud that I can hear it from my bedroom on the second floor. My 7yr old son complained to me that he woke up in the morning because of the noise. I end up shutting down the pump before I leave for work (don't want to wait for my wife to tell me so
).
Another thing I need to do is fixed first the overflow drain. Rightnow, the splash from the overflow is too loud. I need to bring up the 90deg elbow fitting on my durso pipe higher so that the level of the water in the overflow box is close to what the level is on the main tank. Hopefully, this will fixed splashing noise.
Here are some more pictures.
Return pipe with 1 connected seaswirl. The other end of the pipe is for another sea swirl. There is a weight on the seawirl to hold it down.
Both left and right sides have sea swirls already.
Here is picture of the tank before the sea swirls were installed.
Sparss, you are right the barracuda seems to be too strong for a return. If I can't fixed the noise level in due to that pump I might replace it with a sequence dart.
Jerone, thanks for the complement. My plumbing is not perfect. I got water leak evey where. I talked to Rolly last Tuesday he said you're be helping him reaquascape his tank. I'm pretty sure you gonna be breaking a few frags a long the way. Tell him to save it for me if he don't mine.
