Hydor Koralia Super-Mod

Looks like the only drawback is the size. Even the nanostream is too big for my taste but at least stick it at the corner wasn't too bad looking.

Will the suction cup pretty much make it impossible to slide the pump around the tank by moving the outside magnet? If so can the suction cup be removed?

The suction cup can be removed on both magnets. I wouldn't suggest it though on tanks with glass thickness greater than 1/2". The suction cup just gives you that extra security in holding the pump up.

Peace,

But, even the nanostreams are hard to move around without actually getting in the tank and moving them around because of those tiny rubber feet on the magnet mounts.

Come on guys... this is getting ridiculous... read the title of the thread. For general "what is a koralia" chatter please post in the regular hydor koralia thread - this one is for modifications to the koralia.
 
Unfortunately after a thread is split, it is difficult to do a search on it anymore because the old thread is usually, well old so it does not show up on the search list. How about a link to that big thread?

Can't the RC mods fix that search issue?

About 2500 GPH with a MJ 1200 magnet and an Octura 1440. This estimate is based on the commonly accepted estimate of what a modded MJ 1200 with that prop does, and comparing it directly with the modded 1200. It puts out the same if not a bit more than the MJ (more maybe due to the more porous shroud).
 
Kroe, thanks for the idea! I modded 3 of the koraila 4s tonight. I used the stinger 1.5 inch props on mj 900 impeller magnets. I did the rigid tube into the magnet mod. All I can say is WOW! These pumps are outperforming Tunze and Reun by appearance of the water movement. I directed them to exactly the same direction as tunzes and they blew up detritus into the water column. I didn't think I had detritus...And the pumps start in the right direction most of the time. Worlds most awesome 5 minute mod!

Glad others are trying this mod.

I think that if you make the new magnet, prop assembly the same length as the stock one it will always spin the correct direction without a stopper. I haven't tried it though.

Anyone tried a really big prop on this thing?
 
what prop are you using ken? I'm using the one I got from you and I can't seem to get it to spin underwater however it does spin partialy out of the water..not like that helps
 
What happens when you start it out of the water then put it in?

The one I gave you was an Octura 2035. Are you using that with the stock magnet or a MJ 1200 magnet?

I was using an octura 1440 (about the same size as the 2035) with a MJ 1200 magnet.
