WarDog's Tank Thread : Episodic Trial And Error

[WarDog]

Leak test passed with flying colours. Bulkheads good, PVC glue good, unions good, floor and stand survived.
Took about half an hour to get the Herbie dialed in. Stupid quiet. Plugged in the heater and will probably add some vinegar once it heats up.



Here is the power failure test, water level only rises about 3 inches.



One slight problem. The vibration from the Eheim compact+ 5000 is transferring to the stand through the plumbing and is being amplified.
The wife pretty much told me to fix it or move out, lol.
The clear tubing off the return is only 5 and a 1/4" long before joining the PVC and I think is too rigid.
The pump has suction cup feet and is sitting on a OXO silicone sink mat.
I'm going to try to find some 1" ID silicone tubing and perhaps shorten the PVC on the return riser by several inches.
Anyone else had this problem? Any advice?
Thanks for looking.
