how to elminate micro bubbles from etss skimmer?

popper231 · 07/16/2010, 10:31 AM

some reason the skimmer output a lot of micro bubbles, therefore goes straight into the dt. anybody know how to get rid of these? my return pump is a mag 12 with the foam attached.

thanks

Run the skimmer output through a sock.

+1. I put the foam sleeve that comes with it around the output pipe and that conveniently fits perfect in the neck of a short filter sock...no bubbles.

popper231 · 07/17/2010, 03:29 PM

i did the foam sleeve+filter sock connected to the return pump, no luck. i'm not able to connect the foam sleeve and sock to the skimmer output. the bulkhead won't fit any sock.

Which ETSS skimmer? It should go on the outlet pipe past the gate valve.

jaygalindo · 07/17/2010, 05:42 PM

maybe too much flow going through skimmer????

popper231 · 07/17/2010, 06:29 PM

etss 800, no room for sock/foam at the outlet pipe. show me your picture.

popper231 · 07/17/2010, 06:30 PM

if i restrict flow, it will overflow the skimmer. also, that didn't help. still bubbly.

i contacted etss, lets see what they say.

you restricted the output, try to restrict the input, the feed pump.

jaygalindo · 07/18/2010, 09:43 AM

what pump are you running?

popper231 · 07/19/2010, 12:26 PM

doesn't restricting the input wears down the pump? if not, i might have to change the plastic hose to pvc to install a valve.

i'm running a mag 18

the rep from aetech etss was not much help. a lot of his answers were "maybe and i don't know"

I think that he meant that you should restrict the outflow of the pump before it enters the skimmer. You are correct in thinking that you don't want to restrict the input to a pump.

If you are not using a proper sump for that skimmer you will always have micro bubbles in the tank.I am assuming you do not have a UHF sump or equivelent..A properly designed sump would have a few bubble traps and also a filter sock where the tank drain hits the sump.Also at times Bio bail is used to remove residual micro bubbles if a smaller then recomended sump is utilized.

popper231 · 07/22/2010, 01:19 PM

i have tried the iwaki 55rlt which is the recommmended pump for etss 800...same result. i fixed this problem by moving the return pump to a different chamber as the skimmer return.

not something i want to do, but for now it'll have to work.

rigleautomotive · 07/22/2010, 01:37 PM

SUMP not PUMP
you are missing the point here.The proper sump would have baffles with the return pump being mounted on the opposite side as the skimmer output.I think you have acomplished what I meant by moving the pump though .Check out the design on the UHF ETSS Sumps http://superskimmer.com/SumpsBerlin.htm
and you will see what I mean.

popper231 · 07/22/2010, 03:27 PM

the sump is designed with bioballs, but i used lr instead. yah i know what you're talking about, but i don't have that type of sump. there is a chamber for return. it's not ideal, but this will work.

JoeRonda · 07/22/2010, 07:07 PM

It is really no wonder why you have micro bubbles getting into your D.T. Your skimmer output is right next to your return pump, and there isn't enough distance to allow the bubbles from the drain and skimmer to dissipate and pop. You might want to consider another sump idea, I don't think that is a preferable design. .....Sorry to be the bearer of bad news.

popper231 · 07/26/2010, 05:21 PM

yah thats why i move the return pump to the middle section. the output goes where the skimmer pump is ,that creates tons of bubbles....now that i moved the return pump to middle, no more bubble, but less ideal because some water won't be skim

johnnyb05 · 09/09/2010, 07:45 AM

i have used a small amount of bio-bale in my sump. the water has to flow throught the bale and it will get those little suckers. it does a very good job.
