Airmaster Pump

Still running strong and very very quiet.......

The cheapest place I found for a Rena was from Big Al's (the 400 was only 50 bucks or so & it was between 80-90 in my lps).

The smaller Renas dont have an adjuster but the bigger ones do.

I found that by oversizing the air pump for the tank (by alot) I can keep it turned waaay down & the thing runs almost silently & I still get enough air. (My 37 gal is next to the TV & it was driving us nuts. Then I noticed that my 2.5 gal was silent & I finally figuered it out)

I do use only Rena's now though. I tried a lot of different brands & just ended up returning them (An employee gave me a really weird look when I asked to plug it in in the store before I bought it - I was so tired of returning them! )

So far the Rena's have been the quietest of the lot.

Just my 2 cents!

are airators even required in a goldie tank?? just wondering becuase i have a couple but they are really loud cheapos.

Having air bubbles in a tank - from an airpump and a bubble bar/disk/stone lifts the water from the bottom of the tank to the surface of the tank, increasing circulation and incresing the oxygen that is contained in the water. The oxygen comes from the water having contact with air - at the surface mostly, but to a lesser degree from the bubbles. The larger the bubble, the less surface area for the air and the water to mix, so you really want to have as small a bubble as possible. Millions of tiny bubbles have a lot more surface area than hundreds of larger bubbles.

In a tank that is deep, oddly shaped, under medication (which can often dramatically reduce oxygen content or fish's capasity to process the oxygen), or is warmer than usual (in the summer particularly), extra oxygen is not only a good thing, it is essential.

Yes its silent running and I have it set up on a pump tray hanging between my two filters.

Mine is on a flex bubbler wand and according to my DO test: 12mg/l this is set up on a 55 gl with double emporer 400's.

The pump is made by marineland who also makes Penguin and Emporer filters.

This tank is maxed out you could say!

Hi - How is that airpump holding up? I have not seen those - where did you find it? I would like to compare that to a Rena of similar size... Thanks!

I have noticed this, too, and have been thinking of an upgrade on this principal:

I found that by oversizing the air pump for the tank (by alot) I can keep it turned waaay down & the thing runs almost silently

It also gives me room to adjust the amount of airflow if the temp goes up, the fish is sick, or whatever else might require increased O2.

I have been wondering if the spray bar being placed above the bubble wand was a good idea or not (it is the only place for both) but Daryl has answered that here! Thanks - again!

I get these microbubbles that float around in the tank - sometimes it doesn't look so pretty (like the tank is foggy) but if its good for GN, it's very cool!

Its so very quiet and still runing strong. I found it at Dr's Foster & Smith.
