All I had with the sureflow or GS2 is problems. Really bad humming, 2 mjs broke on the back, the propeller cracked on 2 of the gs2.
 
So where can I get the new and improved sureflow kit, I see it on algaefree's website, but don't know where to actually buy it from online. Marinedepot just has listed the old kit.
 
my high flow GS2 has been running toally problem free for about 3 weeks now... I am installing a 2nd one as soon as I get another MJ
 
Hey it looks like you can get the new version for free.

I have an old Sure Flow 1600 Kit. Can I upgrade?

Yes, if you have an old kit we can send you the upgrade kit (free) which includes:

1. New high flow propeller(for use with Maxi-Jet 1200 only)
2. New adapter bracket to attach original Maxi-Jet brackets to full rotation bracket (no glue required)
3. New much stronger rotation bracket, made of new material for added strength

To get an upgrade kit for your old sure flow, send a copy of your receipt, or UPC code cut from the Sure Flow box to:

Algae Free, LLC

Is Algae Free Planning on releasing to distributors anytime soon or is my best bet to purchase another and send them the UPC?
 
You can get the high flow mod at premium aquatics for the sure flow. IMO its the easiest mod that works great. The sure flow high and GSII are both great for larger tanks.
 
I recently picked up a SureFlow 2000 and a GSII kit. The SureFlow comes with an impeller assembly (magnet, impleller, shaft, etc) all ready to go. It also includes the props for both the 1600 kit and 2000 kit. I went with the larger prop on my MJ1200. The mounting bracket is nice as you can use it with your existing MJ mounting options. The flow is sick. My scientific observations make me believe it's flowing more than my Tunze 6100.

The GSII is very similar, but only comes with one prop and you have to reuse your MJ magnet and end caps. You also cannot use stock MJ brackets with it. For these reasons, I'm favoring the SureFlow.
 
I recieved my new sureflow mods last night. I was running the old mod on a 1200 and just installed two of the new ones on 1200's and I am gettting a lot more flow from them. As for noise the new mod makes a slightly louder humming noise but no chatterring
 
I definitely get a humming noise, but I think that the humming mainly comes from the pump vibrating the mount and transferring the vibration to the glass of the aquarium.
 
That seems right as there is a good amount of movement by the ph.
On another note I snapped the mount on my original sureflow when I tried forcing beyond its limitations. Could I attach a magnet to the back of the MJ and have it mounted as such? At current I have it attached to the original MJ suction sup mount but that limits my placement.
 
GSII high flow is giving me a lot of problems now. I was mixing salt for about 22 hours and all of a sudden the mj1200 started chattering really bad. I have an extra ecomod so it isn't a big deal but the GSII kit will not work at all.
 
I have 4 GSII, they all broke. I got replacement parts for 2 but The are rattling again, so I think they will break too.
 
what did they replace?

I have used this pump kit for maybe 5 water changes and its now broke. Can't believe it broke so quick. I have 2 ecomods running 24/7 for months on mj400 without any problems.
