Just another question about Koralia 4's, with 1/2" glass will the magnets hold OK, I thought I read something about the magnets being a bit weak but I can't find anything about it when I search now.

I've used a K4 on 1/2" glass without any issues. Had one on 5/8" glass for a little while as well and never was a problem.

I have some SunSun brand 1300gph powerheads coming when I researched them tons of reviews state they have better mag's then Koralia. Ordered 6 - 1300/gph for $150 INCLUDING SHIPPING.That again is just my 2 cents.

I have two Sunsun's in my 115 cube. They are AWESOME. Two solid thumbs up on these guys.

Neal, of course everything depends on different things like tank size and shape, but for the most part, it's difficult to overdo flow.

Ryan, there is one possible detriment to the Maxijet Sureflows .. at least I found this. The impeller shafts last only about 6 months or so, and then they corrode through. For $20 it's a not a huge deal to go out and buy another but I stopped buying them - I want my powerheads to last longer than that and I'm not sure what baddies are getting into the tank when things rust. It's obviously not a high grade stainless steel or titanium, whatever that shaft is made of. I've gone through at least 5 or 6 of them and they all met the same fate sooner or later (the corroded shaft).

The #4's should be fine, but if you can afford it, look at the Vortech MP40W. I have run Koralia's exclusively since the beginning, but finally tried the Vortech about a month ago now... All I can say is this unit far surpasses any of my Koralia's for flow and of course you have the ability to change things up with it. the programming in the Vortech lifted hidden filth from behind rocks and crevaces... I can say it works great!
