Danner Aqua-Supreme Air Pumps Review

I've been in the Aquarium hobby for almost three decades. During that time, I've gone through almost every type of air pump made with a large U-Haul box of discarded ones in my garage to prove it. Most air pumps are excessively loud, wear out in a short amount of time. or (in most cases), both. A couple years back I had pretty much settled on Tetra Whisper pumps, considering them the "least bad of the affordable bunch". Then I discovered the Danner Aqua-Supreme Air Pumps.

As far as noise is concerned, there is no comparison. The Danner AP-4 (with dual outputs) is the quietest air pump I've ever used. With every other pump I've ever used, I am aware of them running. I am not aware of the Danner even though it is 2 feet behind my Lazyboy. As a result, I am currently ordering additional Danner Air Pumps to replace all of my remaining Tetra Whispers, each of which will go in the discard box with all of the other "spare" pumps. The Danner AP4 is not as powerful as the Tetra Whisper Model 60 (the equivalent dual outlet pump) but it is powerful enough to easily drive a pair of sponge filters and I will gladly exchange a bit of power for noise reduction.

The adjustable flow on the Danner pumps is beneficial in several aspects. If you need to drive some type of ornament that requires reduced flow (the skeleton on a toilet comes to mind), you can do so. If the flow is too extreme for smaller tanks, it can be reduced. Having this built into the pump reduces wear (thus improving longevity) as it is controlling the motor speed, not restricting flow which causes back pressure on the diaphram, as happens with airline valves.

 

Pros:

  • Quiet: This is (thus far) the single biggest benefit of this airpump. While no air pump can be considered silent, this is the most quite air pump I've used.
  • Cost: The cost is almost identical to the Tetra Whispers. The AP-4 (with dual outlets) is about $16 online.
  • Scalability: The AP-8 is a four outlet model for only $25 (online). Tetra Whisper pumps do not have a four outlet model. Other comparible pumps are much more expensive.

Cons:

  • Availabilty: Danner Air pumps are not readily available at locations such as PetCo, PetSmart, or Wal-Mart. Tetra dominates this market. They only recently became a product carried by Drs. Foster and Smith and I've never seen then available at Big Als. Regardless, you will likely need to purchase these online.
  • Longevity: I cannot testify to how long these pumps last as I've only started using them recently. However, Danner is a respected name in this market. I will assume they are a better made product than the Tetra Whispers. The first of these pumps I purchased has been running for about 6 months with no increase in noise and no loss of power.

Replacement Turtle Dock Suction Cups

 

Zoo Med Replacment Turtle Dock Suction Cups

by Kmuda

Overview:

One of the shortcomings in the world of aquarium equipment are suction cups. Let's face it, suction cups suck.... and not necessarily in a good way. Wink

We need suction cups for almost everything that is placed into the aquarium. Heaters, filter intakes, spray bars, sponge filters, etc.... And suction cups that come with the equipment generally last for about 6 months before they only start to suck in the bad way. The rubber (or silicone) becomes oxidized and you wind up with a suction cup shaped rock that no longer has the flexibility to attach to the wall of the aquarium, leaving equipment that just will not stay where we want it. In some instances, such as with filter spray bars, this can become dangerous. We are at work, our Oscar goes on one of their tirads, and the next thing you know you have a spray bar that is now spraying water on the floor instead of in the tank.

So, provided we are going to do something about it, we have two options:

1. Magnetic Suction Cup Replacements, which are expensive

2. Have replacement suction cups on hand

I chose option 2 and in doing so, began the search for a "standard" replacement. What I found (or was actually steered to by Chile) were the Zoo Med Replacement Turtle Dock Suction Cups.

Why these?

The answer is simple. They are cheap and effective. Cost is $1.19 for four cups and I've used them everywhere. These cups are currently used to secure my Eheim 2215 and 2217 spray bars, the intakes on all of my Eheims, the intakes on my C-360, my Eheim Heaters, my Fluval Tronic Heaters, and my Rena Heater. They have also replaced the suction cups on each of my Azoo Sponge filters.

However, a word of warning is necessary. As stated, I use these everywhere, but they are not made for use "everywhere". As an example, using them as a replacement suction cup for Eheim equipment can be a bit of struggle as the "peg" on the Eheim clips (as it is on most equipment) is larger than these cups are designed for. To get them to work, soak the suction cups in some warm (to hot) water for a few minutes, then attach the cup to a solid surface, and use a pair of pliers to force then clip into the hole, spinning it when it starts to get seated (see the below example).

As proof, here are a pair of Eheim clips attached to these cups.

So I managed to find an inexpensive and (thus far) universal suction cup. Cheap enough that I always have them on hand so that my equipment always stays where I want it to.

You can go the magnetic route, at about $9 per cup. In my house I would need about 30 of these. Yes, it would be permanent, but at a total cost of almost $300.

You can buy Eheim Replacement cups at a cost of almost $1 per cup. Why, when I can get four of these for about the same cost?

So, there you go. A solution to an ongoing problem. Just load up on these cups, have them on hand, and whenever you notice a piece of equipment not adhering the way it should because the suction cup is now hard as a rock, replace it. One less ding on the frustation meter.

I purchase these online at http://www.BigAlsOnline.Com.
