Great active filter - Was able to fully cycle my tank in about 4-5 days. Thank you!
I have been trying to get my tank to cycle for months and my ammonia levels kept on rising so I did some research and stumbled on these filters. Within 6 days my ammonia levels went all the way down and has stayed down since and it’s been over a month.
Sponge was ordered on a Wednesday, shipped Thursday, received Monday. Even though it was that long receiving it, my fault fot not checking delivery time before ordering, because of no mail delivery Sunday, my betta & tank are doing great. Wonderful product! Thank you for making this available.
We had been trying to do a fishless cycle on our 20 gallon tank for several months but it kept crashing. We were getting impatient and somewhat exhausted trying to get this tank going. I had read about seeding the tank with filters like this and figured "What do we have to lose?". We live in Montana and the past week or so the night time temps have gotten down to 40F. I ordered the filter on a Wednesday hoping to see it by Friday/Saturday but USPS was being a bit slow. I kicked myself for not paying for faster shipping figuring that the bacteria would be sitting in near freezing temps in a warehouse somewhere and it would leave nothing viable. Well... the filter arrived on Monday and after a full water change and a little dose of ammonia (3-4ppm), we gave it another go. By Tuesday ammonia was reading 0 ppm, nitrites were 1ppm, and nitrates were already present (10-20ppm)! All my concerns were out the window at that point. We have only had the filter for a single day but things are already looking way better than trying a cycle using a product like Stability. Would 100% recommend these for a first time aquarium buyer.
We were struggling to get out 10 gallon tank cycled and were unsure what to do. My boyfriend came across this and we decided to order it based on all of the great reviews. Once we received the filter and put it in our tank, it took around 6-7 days to fully cycle our tank. We are very happy with this product and would recommend it to anyone looking to cycle their tank quickly!
