The media could not be loaded. 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.
