Rena air pumps

[doogie]

Hi, was wondering if anyone had the Rena 400 and could tell me if the are indeed QUIET and if they liked them or not. I am in the market for an air pump for my 125G tank and would like something quiet with dual outlets.

I have a 400 that I just put in my fish room that runs 5 20ish gallon tanks no problem .
I had a top fin 8000 in there but hum drove me nuts. I find the rena to be very quiet.

With bigger pump. You may consider bleeding off excess air as a mean of controlling the air into your tank. Restricting the push of the diaphragm will make the pump hums and shorten the life of the diaphragm as well.

I found the Whisper very quiet as well. Put them on a foam or hang them on a net will also cut of the echo (resonance) through the hard surface they sit on.

i have tried many different airpums over the few years i have been in the hobby such as marina,tetra,topfin,silent air,fusion air.

none of them are that quiet or last as long as a rena

i have 17 aquariums running at the moment,and 15 rena airpumps.(i dont use any other brand anymore)

Rena it is then, thanks!

I've had the opposite experience.

My Rena airpump's screws became loose and started humming really loudly. I had to tighten it every week or so. I ended up giving up and purchased a fusion airpump. I find the fusion to be way quieter and last longer. I think they were cheaper too?

fusion pumps are the quietest I've ever used.

never had that problem but i do check my equipment multiple times a week just to make sure everything is running good.so it would never get a chance for the 'screws to come lose and make noise'

this may be a long term problem if you dont want to check out you equipment once inawhile

thank you for bringing this to my attention jkam

yeah, I think it happened to loosen from the vibrations it sends off. Most of my equipment is dead silent, so it's easy to tell once something is making noise. I do check my equipment, just not the screws haha.

I've pretty much tried them all and will only run fusions now. I find them not only dead silent, but you can't beat the price.
