Welcome, Caedmonball19 from Nebraska, glad that you have joined us. May your journey bring you the knowledge that you seek, put a smile up on your face, create hours of pleasure to stimulate your mind, an a healthier life style for your heart...from Apollo__Phoenix, Arizona.

As for the Atrium Grates I got mine at Home Depot, you can easily drill any size hole for your PVC pipe.

I started off with a Pacific Hydrostar 2650 GPH (worked great but had a metal core), 2nd pump was a 2300 GPH same brand (went though 2 pumps, they both shorted out), 3rd pump 1670 GPH same brand (fairly new still about 2 months).

I broke down and bought a GOOD pump it's a CYCLONE POND PUMP TM 2100 GPH, 1.6 AMPS, 3 yr. Warranty. Have not installed it yet, will wait until the other pump quits. Watch your AMP draw on your pump, more Amps = more electric = more $$$$$

If you want to view my set up from start to now, check out “Fire Pit … AP” then “Pipe Siphon by Apollo” and ending with "Got Vertigrow?".
