The Life Reef Skimmer Club

Which one is working out better for you, the higher or lower flow?




I got some very surprising results with the flow test. I'm going to hard pipe the output later this week and see if that makes a difference as there was a slight kink in the hose I currently have on there.

With the pump pushing all the water through the skimmer it filled a 1 gallon bucket in 6 seconds. That's only 600 gph.

With the gate valve on the T open letting some of the water exit before the skimmer, it filled the 1 gallon bucket in 8 seconds, only 450 gph.

I did the test multiple times and it always came out the same. Still, I'm not sure if I trust those numbers.
 
They're both about the same with the T and swirling action, maybe a little better with slower flow, but the difference was so small it could have been due to what was in the tank. Also if the measurements are correct, it's only a difference of 150 gph. I haven't tried the stock downpipe with all the flow through the skimmer yet. Either way I'm not going to keep this one. I'm going to try a genx pcx40 next and then decide between that or the 100 px for good.
 
Any of you guys connecting your large VS3 skimmers the conventional way along with the counter current option. If so, does it improve the performance. I have a VS3-72 with a Reeflo Dart pump. I'm thinking of connecting the counter current option in hopes of improving the performance. The skimmer seems to work fine but I have nothing to compare it to. I'm not even sure the dart pump is the optimal option. Even though LR says you can use any pump with this skimmer.

Any thoughts?

Anyone?
 
His skimmer was designed to run two ways, Straight down pipe into a mixing tube like the 36" and smaller or straight down pipe into a tee with 90's on each side. Jeff made the skimmer to be run both ways.
 
Am I the only one that things he has a ton of air flow? That air is so turbulent I'm not surprised he has water level stability issues?

Before you throw the towel on it, I'd atleast try dialing down the air line with a needle valve as mentioned by someone before.
 
Yeah, I was on my phone at a stoplight before. The 48" and larger models have four options standard;
- Conventional
-Counter-current
-Re-Circulation/Co-current
-Re-Circulation/Counter-Current
They all have the T with 45's/90's to make the flow swirl. This skimmer is only 6" inches shorter than the 48", but has the same volume as the 72" so Jeff built it with both options. I'm just trying to figure out which setup works best. There are a lot of options with all those variables. And yes there are stability issues that I can't pinpoint with 100% accuracy yet, but the smaller pump was more stable so I'm thinking of going with something smaller than I am running now.
 
Should have my iwaki 40rt(jap motor) next week. looking forward to seeing the pressure rated difference!

Wow! Do you think it will pull too much air for the 24" body? If so will you just needle valve the air to venturi like someone else mentioned a while ago?

Also, do you have an a meter? iirc this will be your 3rd or 4th pump on that body, would have been nice to record some numbers with all the switching you're going through. :spin2:

If needed I will either restrict the pumps outlet or air with a needle valve. Maybe both. My gate valve is still closed quite a bit with the mag12. So I find it hard to believe that the rt40 will provide too much air or water as it is only ~820gph. Keep in mind, I am running the stock venturi. If I switched to a mazzei then maybe I would have air issues but I have no plans to switch that out.


Yeah, I don't have any air/water flow meters unfortunately. I wouldn't bother unless I could measure both as skimming is a result of both. One without the other doesn't provide much valuable information imo.

I don't think you are going to be happy with that pump on a 24" unless you choke the pump output back.
 
It's going to be the same thing as a result of the most important part of the largest one. The only thing that you can get is the best pump and the rest are not an intended recipient of this application.

Yep, I'll have a gate valve for the outlet. I'd rather get something slightly more powerful in case I upgrade to a 30" or 36". Keep in mind, I have the stock venturi.

If you do upgrade to a 36" that pump would work great. I am running the Panworld 100PX which equal to that pump on my 36". The only thing I have to do is throttle down the air draw. Like to know how it runs with the stock venturi.

Yep. Wattage will be nice with it throttled back too :)

Was thinking about plumbing 1" for the inlet and reducing to 3/4" right before the pump... Any thoughts?
