Day 4
Today I purchased two Hydor Koralia #4 Circulation Pumps. These will be used in place of the 2 Maxi-Jet 1200s I had planned. I also tried to get a shorter flex hose for the fuge but was unsuccessful.
I started out by installing a GFCI but ran into some trouble. Whenever the load wires were connected the GFCI would trip. Not good. Checked everything and can not figure what's causing it to trip. I think I'm going to have a dedicated line installed anyway since my home theater equipment is on the same breaker.
Next I finished up the plumbing and put the Koralias in the tank. I filled the tank to test everything and to make sure there were no leaks.
The overflow kept rising and falling and the input for the drain was creating a lot of bubbles. It also sounded like Niagara Falls. I read about this on some threads having to do with the drain tube collecting air. So knowing my drain line was too long (and I couldn't find a shorter one) I cut the hose to avoid any areas that could collect air. I used a hose clip to make sure it held. I also used a 4" piece of 3/4" PVC and installed it in the 1" coupler to help keep the noise down from the drain water falling into the fuge.
The overflow was still rising and falling and it was still really noisy.
I reduced the flow from the pump with the ball valve I installed and adjusted the height of the overflow drain tube. That finally stopped the rising and falling in the overflow.
Aquafuge's site forum says the flow rate for this fuge should be 4 to 6 times the tank size per hour. That would put the flow rate for my 90 at 360 to 540 gph. The Mag 9.5 is rated at 800 gph with a 4" height.
It worked. The rising and falling in the overflow has stopped and the fuge is a lot quieter. The bubbles were also reduced. I also turned the drain hose to a point where it helped even more.
I treaked the ball valve so it's about 33% closed which hopefully puts the flow rate just shy of 540. I hope this is correct.
I'm going to let it run over night to make sure everything works OK. Tomorrow I will drain the tank and wait for my lights to arrive which is suppose to be Tuesday.
Time to relax and do some more research.
The next update will probably be next weekend unless I can find time during the week to install the RO/DI.
