My experience: I change from cannister to sump in a day. Just make sure that you have all your overflow and piping checked and confim working before the switch. Cheers JC

Some info on Sine wave created by UPS. Sine Wave: This is the best waveform, as it is the shape of an (ideal) AC electrical signal from the wall. Square Wave: The least desirable output waveform type, a square wave is sort of a "flattened-out" version of a sine wave. Instead of the voltage smoothly increasing from the negative maximum to the positive maximum and back again, it shifts suddenly from negative to positive, stays there for half a cycle, and then jumps to full negative and stays there for half a cycle, then repeats Modified Square Wave: This waveform is a compromise between the sine wave and the square wave. The positive and negative pulses of the square wave are thinned, separated and made taller, so the peak voltage is much closer to that of a sine wave, and the overall shape of the wave more closely resembles that of a sine wave.

Gd idea but must know exact series that can be used 1st.

I think these are also known as "stepped sine wave" that is used in the backup RS series?

Wat return pump u using?

My plan is to run my eheim 1262 return which uses ard 80W. Based on APC website, can at least run 1hr when power fails. May even consider the 1000VA if price is good.

Roidan has tested APC UPS before. He found that the Smart UPS can be used due to the waveshape been some Low-distortion sine wave. The cheaper backup UPS does not run his tunze. On-battery Me also thinking of getting the APC Smart UPS700VA. 990_7020C7_en.pdf

I see. U mean can get those convertor type and plug it into the UPS before the power plug. Can share a pix on your UPS? Its a gd idea. Maybe can strip the extension cord of its cable and replace with the standard cable used by UPS. Thanks Bro.

Hi Roidan, Just wondering, how do you connect up the equipments to the UPS? The standard power cable for the UPS is meant for computer leh.

Hi Bro, What's the model you using?

Let's keep this thread "clean" and focus on the topic. I actually adjusted the water level higher initially because I wanted to aid the skimmer to break in. Do note that typically, new skimmer will need a few days to break in due to acrylic and pump having some sort of "oil" layer. In the picture, the 2nd O-ring are actually make up of very fine bubbles. The water level (turbulent water) is about 1" above bottom o-ring. Due to the power failure last night, I was not able to review the skimmer performance. I have since re-tune the skimmer. The water level are now below the bottom o-ring. Shall keep track of it again and report back once there any updates. Cheers JC

Base on my observation, controlling the air intake to the beckett injector is important. Since most of the time the air tube will not be open to the max, do not know if draining the water will actually work.

This is actually the picture of it running on MD40. Will be taking more pictures as it break in.

I'll be releasing my Remora Pro with Extrema soon. Let me know if u interested. Cheers JC

Angle shot of this skimmer to share till I continue again tomorrow.

Results Below is the close-up on the dirt that are collected in the cup when using a MD55 after 2hrs. I'll be updating this thread on the performance of this skimmer that is currently running on MD40. Stay tune for more.....

This is a picture of the exact same skimmer that was test running on MD55 for less than 2hrs.

Tuning/Adjusting After checking all my plumbing, with the gate valve, I started the pump. Jet of water with many bubbles are released into the chamber from the beckett smoothly. As this is my first time using a beckett skimmer, I spent a some time fine tuning the skimmer. First, I adjusted the gate value to allow th e chamber to be filled with water. Once the water is up till the neck of the collection cup, I start playing with the air valve to create foam and control the bubble size. As my pump is new, I expect it to take a few days to break-in. Below is the picture of the skimmer after tuning and running for about 1/2hr.

During setup, I was presently surprise how flexible this skimmer is built. The connector for the beckett to pump’s hose can be rotated 360degree depending on requirement. The skimmer by itself (without water) is fairly lightweight. The only compliant I’ll have is some of the pointed edge although this can be rectify easily with some filing. Installation is straightforward. All components fall into place and securely without any difficulties. I spent more time trying to figure out how to connect the MD40 to the sump instead.

Another clearer picture of this beautiful Skimmer.

Another view of the Chamber.

Spots on. U have good eyesight!

Components - 6" diameter Chamber

Components - Gate valve for controlling returns

Components - Beckett with two air tubes for define tuning
