Eheim Sludge Extractor?

Do any of you own the Eheim Sludge Extractor? Ever seen it in action?

With Glosso and Hairgrass--combined with a breeding supply of Cherry Shrimp--I'm looking at ways I can clean the EC substrate without losing shrimp in the process. Using a traditional gravel vac has been a little difficult. I like the fact that this thing has internal filters which presumably would catch the shrimp. Of course, one could always add a filter to a standard gravel vac, too.

I have alot of shrimp, a lot of shrimp poo, and hair algae around the substrate as a result (I think).

Got one of these, its not bad in removing mulm, but you end up with cloudy water in the end cause the water sucked in is returned in the tank.

Makes sense. I'm thinking a turkey baster might be best: stir up the mulm & them siphon it all out of the tank.

This vacuum is not recommended by me.
Bought one last night, taking it back today.

It has the worst suction, and useless imo.

I think I will be making a power vac from a power head, 2 liter and filter floss instead. It just does not pick up the muck like I expected. Especially being a Eheim product I was rather disappointed.

Never bought them, but the petco and petsmart near me put these on clearance last year not long after they started carrying them.

You'd probably just be better off with something like the fluval edge gravel cleaner. It's cheap and has a low flow rate, so you can suck up all the muck without inhaling a bunch of substrate or critters. I can clean up the messiest parts of my 20L with only about 2-3 gallons of water coming out, which is easily replaced.
