Lewisia 5W Solar Air Pump Kit with Air Hoses and Bubble Stones 3 Working Modes Pond Aerator Bubble Oxygenator

Ok I I loved this Solar Pond Pump. Helped my fish to breathe in Hot California Summer. We have a large waterfall but have to place another Bubbler on opposite side of Pond so fish can stay healthy and breathe much better. These always break within a year. It doesn’t matter which brand I buy. It’s so upsetting. I wish manufactures designed these better. It works great when working but now died and have to search another brand before Summer Heat.It’s a myth fish can breathe under water and live happily, they need Oxygen “Bubbles” Constant Waterfall Splashing, they need Aeration. So please have waterfall plus Aerator for Pond or Fish Tank. Especially if Hot or Power Outage. It’s good to have a Solar in case our Power Goes out in Heatwave or bad weather and fish need to still survive so solar is great option. My 40 Large Shubunkins & Comet Goldfish need plenty of oxygen in summer Hot hot weather. The warmer the water the lower the oxygen for your fish making it difficult to breathe. So make sure they have tons of bubbles or oxygen always flowing when it’s hot outside if you want healthy living fish.Everyone should have solar Aerator on hand in case of power outage. Otherwise you have to splash water on surface & create bubbles on your own several times an hour so your fish can breathe until electricity comes back on. Tip use a bucket & remove pond water with the bucket & dump it back in “creating splashes” several times an hour. If power outage does occur & have no Aeration. You must create bubbles “oxygen” in the event of power outage. If fortunate Aerators might last a good year. So why pay more then $50 for something that will crash in less then a year.

I live in an area with Sulfur smell in the water. This is caused by the Dihydrogen Sulfide Gas that is produced by Iron eating bacteria and becomes dissolved in the water. I bought this to aerate my water storage tank and pull out the H2SO. While the pump worked this was a fantastic little setup. The Solar Cell still appears to work and is showing status lights and voltage on the connector. The pump itself no longer works.The pump is supposed to be constant use but it failed in less than two months.Update:Lewisia was kind enough to send me a replacement pump which I installed and it worked. However, now less than two months later the pump is not capable of pumping air hard enough to produce bubbles through the aeration stones. This has served as a good proof of concept for me but the pump is just not of good enough quality to last more than two months of continuous use. This is a bit disappointing as I liked having a device I didn't need to plug into the wall.Update:I really didn't want to give up on this as it was working fairly well. The conditions of the pump is inside a Rubbermaid upright storage housing underneath an eave of the house. It is well sheltered from the weather. The hose and power enter in beneath it preventing weather elements from affecting the pump.I performed some maintenance on the pump. The following is probably not for everyone. I removed the four phillips head screws from the housing. Opened the cover and loosened the wire restraint. I needed a precision phillips head screw driver for those on the pump. Upon opening the actual pump head I discovered a good amount of dirt on the inlets and on the pump diaphragm. I cleaned them off with qtips and distilled water and then reassembled the pump. I put in back into the system and it started pumping air again. Unfortunately this little guy has no filter on him so I will have to make this part of the maintenance for the pump in order to keep it working. Happily this is a fairly easy clean though tedious.I've raised my score to 3 stars as the product is salvageable and does do what I want it to do again.

I bought it 2020, I was building my pond and wanted to make sure water moved a little. Welp it sat unopened for two years finally set it it this summer and in 3 months it stopped working. The panel charges fine gets great exposure but the pump is dead, if there is a replacement pump available I want to get it to not waste the solar panel but they don't seem to offer one.

This pump worked great right out of the box with no preliminary charge time, and with the battery backup, it was still working the next morning. After about a month, it stopped working. Unfortunately, the manual is minimal, and includes no troubleshooting tips. I watched it for several days and then contacted the company. I tried cleaning out the air intake hole and cutting out a small kink in the tubing, but it still wasn't working. Because I wasn't sure how long it would take Lewisia to respond, I did my research all over again, and when I couldn't find another pump with the same features (bubble stones instead of a fountain, solar power, backup battery), I ordered another one because I'd been so happy with it when it was working. The company contacted me right away and offered me a replacement, but since they'd also noticed that I'd ordered a new one, they offered me the option of a reimbursement. Meanwhile, the new pump arrived and I took it out to the pond to connect it. But when I picked up the old pump, I noticed that it was vibrating. So I pulled up the stones, and sure enough, they were bubbling merrily. I still don't know what I did to fix it (although I did push all the buttons again before I went to disconnect it) or if it just went on vacation for a week. But I am, once again, delighted with this product.

Have this for a small water trough to try and keep it clean. It does the job when it works which is not that often. The solar panel is in a tree with no branches in its way for sunlight. It will work for a day or two then stop working. I also have the two stones hooked up and only one will ever work at a time.

I have been using this pump for a good while now and it works greatIf it gets enough charge during the day it runs through the night. I use it in my fish pond which is located outside and I can hear it in the house at night
