glass thickness.
 

It says on the hydor website that the magnet is good for 15mm glass thickness, Which is 0.591 inches. The design also incorporates the magnet into a suction cup, so you would think it should work fine.

Mine is attached to my 220g, which is 1/2" glass. It works but not as strongly as my NanoStreams' magnets. The HK4 stays in place & that's all I ask of the magnets.

Paul's Aquarium <- Wholesale Outlet. they have plenty in stock and is recommending the HK's if your worried about too much flow they have sizes 1 through 4

Anybody got a 6 month update they'd like to share?

I'm currently running a 1 and a 3 in my 40, and I still love them. Easy to clean, no chatter and no problems.

I just bought a couple of #1's the other day and they are working great no noise at all. doesn't feel like there is much flow though not use to the disburstment that they give out.

I would also like to know if anyone has any problems with them.

Koralia
 

I'm in the middle of trying to choose between 2 Koralia 4's or 2 Tunze nanostream 6045(1189gph). Tough decision. Heard lots of good about Koralia and Tunze. I'm not sure if a Koralia is designed to work with a wavemaker though.

No they aren't i was talking to a guy today about that and the motors burn out because they aren't ment to be turned on and off appearently. My advice i was given was if you want it hooked to a wave maker i would spend the extra cash and get something garuanteed to work

I have had my Hydor #2 for a good couple months, and no problems whatsoever. I will be buying a couple more here soon too.....

I have both and prefer the Tunze.
