That might work for people who want the 25s and 40s, but not the 60s. :) Sent from my iPhone using Tapatalk

Yup, I can look into adding you into group buy. When did you want it? How soon? (I am in Berkeley nowadays, BTW). Anyone else want in to try these pumps? I will check to see about buying a mixed set of pumps Sent from my iPhone using Tapatalk

A voltmeter does not measure frequency. One way to find an approximate voltage is to put an RC low pass filter to smooth out the PWM pulses (or hook up an oscilloscope). Otherwise, your voltmeter will not register the actual pulse width modulation. Only other way is to KNOW your PWM is...

Oh, I did not specify... For those that are wondering, there will be a partition wall build all around the tank sides. So the columns will be squared out and covered with marble/tile/laminate. TBD. This is the existing stand but I am trying convince FIL to change it to metal stand. Better...

I may end up putting together a buy for some, since I need to buy two anyways. PM me if you want me to ask about adding items for you guys. Sent from my iPhone using Tapatalk

Water over a drain that has no air in the pipe and is draining is operating as a full siphon, no? The challenge is usually keeping enough water above it to keep it under full siphon conditions. As for horizontal runs, are you referring to the pipe friction loss that occurs? A vertical...

I think it depends on how much "water height" and if you are running a siphon drain. Siphon drains can do like 3-5 times normal "aerated" gravity drain flow. Is that what you mean about the bulkhead flow rate? Sent from my iPhone using Tapatalk

Depending in how long it takes to set up my inlaws 240 lee mar, he wants "softies" so he will be interested. Sent from my iPhone using Tapatalk

I think I need to leave the slots on bottom so I can get enough "flow" through the tank. I probably need 240 gallons x 6~8X per hour turnover. So that means about 1440GPH or 1920GPH According to this calculator: http://reefcentral.com/calc/drain.php If I target 1500 GPH, that means I need...

Yeah, that's what I figured. Or else the original "leemar" tank was "mis-designed" by the original owner.
