Penn-Plax Bubble-Wall Aquarium, 7-Inch

Works well. A whisper 40 would push enough air switched to whisper 100 and its more than enough! Probably somewhere between 60-80 would be ideal. the bubbles are nice and consistant (and small) LOVE IT!PRO-TIPs: If you are using multiple wand shafts connected and you don't get consistent bubbles across the whole length:1) make sure all connections are tight a little leak can kinda kill the second wand section (if its hard to get a tight fit, carfully shave the ends of bubble wand material with a scalpel or razor blade.2) If that does not work try running air to both ends to even out the bubble flow.3) If that still isn't working your pump is too small.would have given it 5 stars had the instructions been better/ had pump to length suggestions. Still it is the best product I have gotten for this function. DEFINITELY RECOMMEND!

I bought the 23" to install in my 40 gallon tank and use a 75 gallon pump with 4 air outlets and variable air output. First, the wands are cheaply made and are quite flimsy. You must be careful when assembling not to break the air tubes. Biggest issue I had is that because my tank is almost as deep as it's long (24" deep x 32" long) getting the two assembled wands to the bottom of the tank without the two halves separating was nearly impossible. because the wands float and won't stay down without the suction cups attached to the glass (this may not be an issue with the shorter wands or with shallower tanks) they kept separating and water would enter the air tube so I had to start over and could not reassemble under water. I started with the suction cups attached to the glass and then I would slide them down a little bit each side but half way down the two halves would separate. I found somewhat better success with having the suction cups attached to the glass at the bottom of the tank and then submerging the air wands and clipping them at the bottom. A 30 minute royal pain in the a$$ that should take no more than 5 minutes.The reason for the 3 stars:pros:* The first half does produce a beautiful bubble wall with different size bubbles that looks amazing in the tank.* Price; it does not get any cheaper than this to get a bubble wallCons:* Difficult to install ,have to guess a lot and figure out your own method* Second half or wand does not get enough air so while it produces bubbles throughout the whole tube it's less than half the intensity of the first half.Eventually I will follow the advice of some of the reviewers and get to the task of cutting the second half and bevel it and see if the connection improves to make the "wall" more uniform. (maybe when I do the next large water change and the water level is way down in my tank)I saw a question that read that you had to poke the holes in the wand yourself. this is NOT the case the instruction read that you only have to punch holes in the event that you have hard water and the wand is clogged after having already been used for some time, then you can "revive" the wall by puncturing holes with a needle. out of the package you do not need to do this. If your wands don't make bubbles out of the box check for air line kinks or blockage and lastly you may need a larger air pump.I recommend purchasing the blue air line they sell in amazon as it really is nearly invisible under water and extra suction cup clips to keep the air line out of the fish way.

First let me start by stating I absolutely LOVE these Bubble walls/Wands. They are the best I've ever found for our aquariums. This review will be my first and I hope as thorough as I am (detailed) that my review will be of great help and informative as I intend it to be.I will say, some reviewers seem, in the kindness words- A little unknowledgable in this subject as per their reviews I have spent a great deal of time reading. There are some perimeters you need to know, understand and consider before installing and writing bad reviews.First and foremost, these come "Pre-Holed" if you will. There is no need to add holes unless you so desire. It comes completely ready to install and work beautifully as originally intended. They are also most easy to cut the length desired with a simple razor blade and clipping the end cap back on😉. I have included pictures and video of the fully working Bubble Wall with no issues whatsoever ☺️.The second thing you need to consider is your air pump. How much air does it put out and for what size aquarium is it intended?? I find, my bubble walls all work best with larger size air pumps than my aquarium actually calls for. Such as for this installation I purchased the MillionAir MA-600 also on Amazon. It has double outlets, variable control and is equipped to handle aquariums 60 gallons and up. I have never used any air pump that is equipped for an aquarium less than 30 gallons. Usually the "200" version of most air pump company's line on pumps. As Bubble walls of this fine quality require more air to be pushed through to achieve the fullness of the product.The third thing to consider is how long of the airline tubing you use and how deep the aquarium. The longer the airline tubing, the longer it takes that forced air to pump down the line to get to the Bubble Wall. The depth can sometimes greatly impact your Bubble wall and its performance. As the pressure and flow it has to put out will need to be greater for larger, deeper aquariums. Therefore the need for a larger air pump is required to compensate for the longer air line and/or the increased depth.The forth thing to consider is, are there any large bends or crimps in the airline?? If so, the less bends, there are, the easier airflow is allowed. If there are any crimps, you will have significant issues in getting your Bubble Wall to perform at its very best or at all for that matter many times.As I have stated before, I just absolutely love this line of Bubble Walls opposed to the alternative "Stone Bubble Wall". This material creates lovely, exceptionally fine, and an abundant amount of bubbles. I personally enjoy, not only the amount of bubbles, but the fineness of them. The are tiny and inviting. No only to the aquarium inhabitants, to the the curious viewer from the outside. To express this to you all, I have included photos and a video to show just how wondously abundant, extraordinarily fine and intriguing the Bubbles and this wall truly is😉.I have also found I can install it under the gravel, and looks great, but works be unobstructed at the bottom of the aquarium, directly on top of the gravel in the back.I must mention that our Fish and Cory Cats (catfish) Absolutely adore this Bubble Wall. They all LOVE to play in and out of the Bubble Wall. Running up and down it and inside and out. Especially the Cory cats!! It's their favorite thing to do most of the day when not sleeping. I've even seen some of the catfish sleeping next to or sometimes on the actual Bubble Wall. Very relaxing, fun and entertaining to our inhabitants and us viewing them!! ☺️ I simply made their world better by removing a shorter version of this to replace it with a much longer and substantial one. They are thankful!! I will use the shorter one in another aquarium.My Husband has also even broken the one we originally purchased at PetSmart (when I was hooked years ago) 3/4's of the way at the end and all I had to do was cut it of with a razor blade and clip the end cap back on and vola, it was fixed!! Just a little shorter!! 😃When I installed this particular Bubble Wall/Wand I did not alter it in any way. I just pushed the two halves together (no sanding down or beveling) moved the suction cups down to the ends and middle respectively (on the actual bubble wall, not on the plastic ends) and it is working just as specified. Beautifully I might add!!The pictures and video I have included show the Bubble Wall on the lowest setting and highest setting of the MillionAir MA-600 air pump, also located on Amazon.I hope I have remember to put all I wanted and that has been stated in previous reviews into my own. I also hope this review has answered any questions or concerns anyone else has or had while in the thought of purchasing this particular product.

I have been using these now for a few weeks and there's pros and cons to it as with anything.The pros of it is the beauty it provides for the backdrop of your aquarium. I've always like the bubble effect on the back of an aquarium.The con is because of it being so large the pump takes a few minutes for it to fully push enough air thru to make all the bubbles going. I guess another con would be if you don't have your aquarium full enough the bubbles do make a lot of noise so make sure you fill it pretty close to the top and that'll take care of the intense bubble sound. The other con is because of it being so big if it bends at all in the middle the air doesn't go to the other side which leads me to the air it does push in it will lift the air diffuser up over time. I had this covered with about half inch of gravel as close as I could to the bottom and the air would push the gravel off of it over time and start moving upward. So each time I do a water change I have to readjust it which overtime is kind of annoying.Also note: when I first got this I soaked if for about 8 hours then turned on the air pump it would NOT pump air into it. Even after 5 mins. So I took it out and poked holes in it about every half inch and it worked Perfectly after! And now the bubbles are perfectly spaced and looks wonderful.SO overall I would recommend it but a word of caution it will add time to your weekly maintence of your aquarium.
