pumps so loud

[dmbnpj]

I have modded the maxijet 1200's and I run 2 of them on opposite sides of my 75 gallon tank. These pumps make so much noise I am sick of them.

Do the expensive tunze pumps work with very little noise? Or the vortech pump?

I modded two 1200 for my 75g. They where so loud, even after a week of running 24/7,I took them out. put mods on 900's were a much better. I ended up going with the Seio 620's.

I have tunze and they are very quiet. I have never had a vortech but the motor is outside and I assume they are slightly louder than the tunze

hydro's are quiet. i have two hydro 4's and you wouldn't know they were running unless you looked at the prop

draleigh are you talking about the Hydor Koralia 4? If so, are those 2 enough for your 180 gallon tank alone?

Thanks

yeah i meant the koralia4's. I don't think two are enough, i also have two maxi 1200's with the hacksaw mod done to them on a wave maker, along with my returns. I am guessing i have about 3000 - 3500 GPH turn over. Food stays adrift and nothing sits on the bottom - no detruis problems my sand is nice a white. They are a little bigger then i expected, but i think they have a nice flow, nothing direct like the maxi mod

How is the sound on the koralia4 compared to the modded maxi jet? I currently run 2 modded maxijet 1200's on my 75 gallon tank and the pumps are sooo loud.

You wont even hear it run.

[dmbnpj]

Dubbin1, do you have any on your 75 gallon tank? If so, how many do you run?

I have 2 K4s on my 120. I don't hear them at all. I don't have anye experience with pumps other than MJs but for bang for your bucks, noise and flow go with the K4s.

Sounds like I am sold on the koralia 4's. I plan on 2 of them for my 75 gallon tank.

Thanks
