RDWC and LEDs: Various strains

View attachment 4238657
Was at Ace hardware today and stumbled across some 3/4" ID tubing. Worked nice to bridge the gap. A tad loose on the manifold side, but real tight on the pump nipple. I closed all the nozzles to test the seal and some air was seeping out. Will need to pick up some screw clamps. Then I opened up just one and air was blasting out of it.

Gonna set this up on my 27 gal tote RDWC. Wicked over kill but I'll power my 12 gal rdwc with this as well and any single tote DWCs. RDWC alone are 250 gal.

Pick up some clamps tomorrow. I wanna get some more for the 12 gal system anyways. The polypropylene piping I got for that was a tad loose.

How much air can that ap100 air pump push out? I can't find the liters/min or gph anywhere.

Those models are named after flow rate. 100 LPM = AP100 ect.

Most pumps are named after their flow rate but I remember seeing a few sites/charts and the Dinner AP-100 is rated at 150lpm for some reason

Yea,,I thought I read somewhere that they were stronger (& quieter) than your average pump and should not go the number. Hence the higher price.

Yeah I have one and it’s way better than the cheap vivosun compressor ones. I’ve heard hi-blow and hailea are quieter but those are really pricey

Yeah but those are flow rates under no load, so speak. Once you start adding tubing and stones, the average output is around that stated barring any long tubing runs ect.. There are flow charts the manufacturer should provide which show this, similar to a waterpump.
Those types of pumps are badass if I may mention. I loved my ET-80. Over the fans and stuff I would have to touch it sometimes to be sure it was running, very quiet.

Those ET 80's aren't cheap either...around $190. Top of the line, no doubt. Nice

Yeah, but FWIW my first grow was done with two 25$ ecoplus 18w commercial pumps. Havent been able to do better, believe it or not....still have those pumps as backup.
The upside to using cheap pumps is when one dies, which it will it can be easily replaced. You can just buy a couple extra just cause.
Just saying.

Ecoplus quieter than the rest? I've been looking up how to make them more quiet...hanging by bunji cord, ect...But I think the first step is start w the quietest of the "cheaper" air pumps first, then work outward from there by trying to make it more quiet.

Here is a picture of the first grow configuration. I originally just had one plugged in, and the other one ran for redundancy to the same tubing. Ended up running both 24/7. The short sections of tubing quieted them down...marginally at best.
Ecoplus was simply the cheapest option at the time. I had no experience with air pumps.
