A question about Koralia powerheads
 

just looking for some help from people who have experience with the Koralias powerhead.
Ocean Aquatics is have a sale on them and I would like to buy some.
my question is are they 4's too strong? 1200 GPH seems like alot of water movement. does it affect the fish at all?
one of the tanks I want to set up is a 4 foot 130 gallon SPS tank, how many 4's would u put in it? I was thinking 4 in total...is that many, I also want fish in there as well....would this be too much current?
as well, as anyone had any other problems with them?

thanks in advance for any input.
Neal

I think 4 will work great on a 4 foot tank, there should be no problems at all with to much flow for the fish.

I think for the money the Koralias are not better than a MJ1200 with a Sureflow kit. Not to mention you are saving a pile of money.

So far all I've used are two small koralia 1's for some additional flow in my frag tank but I have been quite happy with them. I do need to clean them once a week as their design seems to collect algae very well but I dont think many people have that problem.

ive got 2 in my 75 and my fish think its a playground! they love the things

I have 2- 4 and 2-3 in my 90 and my fish think its a playground! they love the things

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!

Ya that Vortech is sweet maybe some day. I am trying to get the 155 BF up without braking the bank & most of all **** off the wife with how much I have already spent,LOL. What she don't know wont her me unless she get's out the calculator & all the bills.

where do you get the sunsun from ?

Got mine from a LFS in Calgary called Ocean City. I don't know how widespread the distributorship is on them yet.

I ordered a sun sun off e-bay they are like $10 + $10 shipping mine didn't seem to have any flow at all. I used the magnet for a sure-flow mod and it works like a hot damn.

Got mine coming from E-Bay as well. Have not arrived yet & can't wait for them to get here.

Where did your's come from? Was NIB or used?
