high flow propeller

i was wondering there is a thread about modding the koralia 4, which will require a high flow propeller(gulf stream 2) where do i should i get it? aquarium supply direct trying to sale it to me for 7 each for 6 for shipping so 2 x 7 + 12 for shipping come out to be 24 dollar. what a rip off, anyone else know where to get them? mod suppose to be for mj1200

 

i might get a modded MJ for my tank to add flow. they are quite imppressive. 2000+ gallons per hour for 30 bux. cant beat it

 

I think you are refering to the Dumas 3004 prop. It can be found at any hobby shop. I just picked up a Koralia 4 in a trade and was thinking of the same.

The only other prop that would be more is the Octura 2035. I examined the prop on the Hydor and it seems to be the same pitch as the Octura 1435 that is commonly used in maxi-modding.

Edit... hmm. that is for 1600 model. I am confused, do you think this will work for your Hydor?

 

as long as you use same magnet, all you have to do is replace the prop on the end on the hydor

 

matt I believe the kit that u r refering to works with the koralia too however as I learned that the the algea free mod kit come w a mj impeller magnet there is no need to buy one from Lfs to do themod. The most important thingisthe flow pattern, for mj it will produce a long stream also jet like it coulddamsge some coral especially at around 2500+ for the koralia it still carries it flow pattern wide and strong it felt stronger than the maxijet so I would expect it to sit some where around 3k+ gph.

 

this mod kit comes with both the 1600 gph prop for the mj pumps 900 and down and the 2000 gph prop for the mj 1200 this larger prop wont run on the smaller ones

not shure if it will work on the hydor but you could get rc boat prop from a local hobby shop to do the upgrades get several different sizes to see wich one works best for your powerhead

 

LIke I said you can upgrade the Koralia 4 to either the Octura 2035 or the Dumas 3004.

 

Watch it, I just added a brand new MJ 1200 with the algae-free kit on Saturday to my 55, supposed to be 2100 gph. I could only find one place in my tank where it wouldn't stir the sand up! It worked out great and I love it, lots of flow for one little ph, but after my day-long experience of moving sand I wouldn't buy a powerhead over the 2100 gph for a 55... just IMO.
