koralia or tunze nano

[davocean]

OK, want to add more flow to my 180 and trying to decide between the koralia 4 or the tunze nano 6045.
Leaning toward the tunze because it's smaller and less invasive.
Main concern is quiet, and temp(I read a comment that koralia4 raised temp 2 degrees?)
What do you guys think?

i have both the koralia 4's and nano's on my 180's.

imo, they are completely different pumps. the koralia 4's reported 1200gph but it 'feels' much higher than this to me. the flow is very wide and it seems to reach halfway to three quarters opposite end of the tank.

i have a koralia on each end with a nano right beside them.

i 'might' not recommend the 6045's as people have been modding 6025's (cheaper) to get more flow than 6045's.

i have noticed ZERO temp increase with my 200g total water volume (adjusted) with the koralia's, nao's and mj 1200's.

i have also noticed ZERO noise with my koralia's and nano's.


both are excellent pumps and would not hesitate getting another koralia 4 and nano's.

I would go with a modded Tunze Nano 6025.

for a 180 you really should be thinking larger, say a 6100 or a modded maxijet

Well, I already have a closed loop w/ a dart @ 3,600 gph, and an eheim 1262 @ 900gph, so flow is roughly 25x
I figure 2 more PH's will give me what I need, and I want small.
I like the koralia's, but bigger than a coke can would take from display, especially since these will be in front corners.
I do like the tunze mod idea, and 2 of those would be perfect I think.
I am concerned about noise though.
Seems everything has a trade off.
Are the tunze noise really that noticeable?
My dart makes a humm that I'm already a little dissapointed with, but hoping my new cabinet enclosure fixes that.

i cannot hear my tunzes on mine and I have two.

The tunzes w/ mods are sounding pretty cool, anyone else think I'm going too small w/ these?
My tank is mixed w/ nems on bottom, some sps on top, plan to get more sps.
Even w/ what little head loss I have this would be about 40x turnover which I think is plenty.
