Turboflotor 1000, reducing splash noise

[dendro982]

Hi, maybe you can help: I find it quite irritating the constant splashing noise from outflow tubes of Turboflotor 1000 skimmer (not Multi). How can it be reduced?

Check with me, if I'm doing it right:
1. In sump Turboflotor 1000, Ocean Runner recirculating pump, Maxi-Jet 1200 as a feeding pump.

2. Water level in sump is 14-15 cm (manual recommends 10-15 cm).

3. Return tubes end within 1" above water level. Tried prolong them under water or use filter bags as an extension, still air bubbles, popping in the water, make main noise.

3. Flow control caps (removable ones) are pushed out by bubbling water it their tubes. Not at once, but eventually they rotate and start restrict water flow, then they are pushed out. Without them - a lot of noise, but less than from return tubes.

4. Recommended water level within skimmer body is when the collection cup is removed, skimmer should not overflow. With Maxi-Jet 1200, commonly used for this, it overflows. With collection cup on, the bubbles level is already in the neck.

Also I found recommendation to use powerful air pump on air intake for increasing productivity. Tried, splashing noise air bubbles from outflow tubes and at place, where flow control caps should be, became much stronger. Filter bags don't help, micron bags are washed away after several hours of work, as well as flow control caps (popped up by flow, very soon).

What I do wrong and how you are dealing with the problem?

try these two things:
1. take the flow control caps off completely, they are kinda useless. that will reduce the water level by allowing more out.
2. if you have a sponge inbetween where the return pump is and the sump area, direct the return tubes onto the sponge. if not wight down a sponge and place it under the return tubes so the water hits the sponge not the water.

I run my T-1000 in 20 to 25 cm of water and feed it with a MJ900 and it works awesome. No splashing or large bubbles. I removed the riser caps and threw them away long ago and installed air airline valve on the air tube so I can adjust the air feed or it skims wet.

Thanks! I'll try to add sponges (as soon as I figure out how to keep them from floating away), they will need to be cleaned at least twice a week, judging by color of filter bags on outflow tubes now.

Changed MJ1200 on MJ900, in the same level of water so far: better, but bubble level in skimmer is still to high - well inside the neck right after turning all on. Caps are pushed up anyway, and without them the noise is quite strong.

AZDesertRat: as I understand, air supply should be limited by air valve, not added by air pump, right?

Yes, The needlewheel pump (OR2700 or Rio whichever you have) provides plenty of bubbles. I have to much air at times so limiting it works better.
I would not suggest the foam, foam filters breed nitrates when not serviced on a regular basis by trapping organics and debris. I will not use any sponges in my system with the exception of a submerged small sponge sock on the suction of my calcium reactor feed pump, a MJ400 powerhead so I don't fill my reactor with debris.

Thank you!
