I have 1/2" thick glass.

With the magnet issue, will the magnet hold the Koralia in place or not? If the magnet is strong enough to hold it there that is all I need, if it keeps falling off the magnet then that is another story.

I have one on 3/8 glass and I havent had a problem but on the half inch glass my rabbit can flip his tail and knock it off the glass. However its been on the tank for 3 months and I have only had it fall twice because of the fish. When I added the maxi mod I spent a couple of hours making it work, the maxi keep blowing the K4 off the glass. Along with the magnet is a suction cup and between the two, do an ok job. Could be better but......

So it looks like I have a choice between a higher priced German unit that will break, or a lower priced one that will fall off its magnet.

I had the Hydro 4 on my 120 the glass is 5/8" and I didnt like the magnets on it that is the only down fall.

It's not super powerful, but I had my HK4 on my 210g with 1/2" glass no problem. I now have it on the 120g with no problem.

Or you could buy the Maxi Jet 1200 ($27), the Sure Flow mod kit for it ($20), and a Sure Grip magnet holder for it ($28-40 depending on how thick your glass is). Then you beat all the problems...

Btw, the Sure Flow mod kit has two propellers in the kit, one propeller will make any MaxiJet do 1600 gph. The second propeller is for the MJ1200 only, and will make it push over 2000 gph. AND, it has a bracket that you super glue onto the Sure Grip magnet holder that allows the MaxiJet to swivel like the Nanostreams and Koralias. PLUS, it widens the flow of the MaxiJet as it uses a propeller instead of an impeller. Both the Tunze Nanostreams and the Koralias use propellers. A MaxiJet originally comes with an impeller.

MaxiJets have a 2 year warranty, and if they break down after that they're only $27 to replace. Well worth the money if you ask me!!

Just picked up a Tunze 6055. Those infamous clips are fine so far (knock on wood

). Looks like they've managed to work the bugs out of the original design and materials used. I think if you purchase any of the "post-fix" Nanostreams their build quality shouldn't be a huge issue anymore.

I've had Tunze pumps -- including the nanostream 6055 -- for a few years now, and they've never had a problem. Admittedly they're expensive, and for the price they should work flawlessly.

Perhaps I've been lucky, but thus far I'd recommend Tunzes. Also, their magnets are fantastic. I've got "0.5 inch glass and they stay fixed like bricks, never drifting down.

Some people have complained about too much noise with Tunzes, but this hasn't been my experience. If noise occurs, the pump may need to be nudged from whatever's causing it to vibrate. Once in the right location, they're noiseless.

I don't know about product support for Tunzes as I've never had to use support.

I worked for a short period at an LFS recently, and there were a TON of Tunze Nanostream returns. There was literally a HUGE box filled with them to go back on warranty work. Some of them ARE noisy, and need to be replaired, some break the propellers. I won't buy one. The Koralias are great for smaller tanks with thinner glass.

I'm the proud owner of two 6045 nanostreams and no problems yet. I believe the problems may have been worked out. Flow wise they are really gentle and have a super wide stream. I'm happy with them. Although I will be getting rid of them once I talk myself into spending the money on the Ecotech Vortech.$400+ dollars though.... Ouch!
