Would Seio PHs be too much?

[runway1]

I have a 55 reef and need to replace my maxi-jets. Would a pair of Seio M620 (620gph each) be too much? I currently have 3 MJ900s totaling ~700gph with my sump pump at about 300 gph.

Which would be a preferred setup for a reef? 2 Seios M620s or 3 maxis MJ900s?

I dont think it would be too much. I am running a modded maxijet(800+ gph) and a Seio 620. This does not include the 700 or so I get from my return.

It really depends what you are keeping. Maxijets are cheap and durable though.

I have 6 SEIOs and 4 of them have already locked up on me. I just bought Hydor Koralia Water Circulation Pump http://www.drsfostersmith.com/produ...&Ntx=mode+matchallpartial&Np=1&pc=1&N=0&Nty=1 and so far, I love them. I found the SEIOs to be a bit bulky, in my 55G. I replaced them with two Koralia 2s and am very pleased.

Wow, roka, those look pretty cool. Does the mag work good at holding them? I hate the suction cup thing. They always need replacing and funbling with. They're a lot smaller than the Seios as well?? How long have you been running them? Thanks!

Yup, they use magnets. I have a pair of 4 on my 125 and on that one, I took off the rubber pieces to help it stick better. I still have the rubber pieces on the 55G. The 2s, you can probably fit a golf ball in it, just for an idea of size. A word of caution, I have only had them for 2-3 months, so I am not sure how long they last.
Overall, I like them, so far.

Awesome, thanks! I think I'll give them a try.

I have had issues with the Seios as well but mine has been running for a couple of years. The ceramic shaft can freeze up and need cleaned more often.

My modded maxijets are great though. Cheap flow if you have the maxijet already.

I will be trying a Hydor 4 though. The smaller units are having some issues from what I have read but 4's appear to be the most reliable.

The Korallias are having issues. They are/where leaking current into tanks, and models 2 and 3 where asked to be sent back for replacement. AFAIK there was no official "recall" though. The new ones will be out approx. 4/13, at last announcement. FWIW I have been happy w/ my Seio 620, though it is a little bulky.

MT79, ellisz, where have you heard of these probelms? Thanks.

On other forums from hobbiest and the vendors that sell them. Here is a link to a thread I found quickly- http://www.reefcentral.com/forums/showthread.php?s=&threadid=1060944&perpage=25&pagenumber=1
