One confident reviewer writes, “ I’m back to order more!! “. Editrice concludes, “ So far i love it! “. Another reviewer says “ Great sponge filter may never change “.
Great price for these! I prefer this smaller size, it’s perfect for any use or tank size and easily hidden! I use them as regular sponge filters attached to the air pump. I also use them as pre-filters on my canister and HOB filters. I even have some attached to the intake of my powerheads for polishing. Yes, the sponges are fine, but that’s desirable since it keeps your water clear. It only take a weekly squeeze out in some tank water, so very simple. I have bought large course sponges and cut them to fit these to replace the fine ones on my canister filters, since the flow is much higher. I have a high fish load in all my tanks, I’m the world’s worst about overfeeding, but over-filter and these still manage keep the water flawlessly clear with very little maintenance.
I’m back to order more!!
Just started w it in my tank but it’s a nice fit in a 10 gallon. Seems gentle for my betta. Tiny bit worried he could get stuck in outflow tube, so i’ll monitor. Edit: i got w a tetra whisper10. Attached flow regulator to turn flow down a bit. (Couldnt bring it down too far or heater wont work.) Put output against a flat leaf on a plant in my tank, so betta wouldnt be tempted to put head in opening. Betta loves the soft flow. He slept w the bubbles his 1st nite in tank
So far i love it!
Love these filters much smaller then the old school sponge filter but I can clearly see it pushes more water through the filter and helps provide a little current to circulate the water, I have 2 one at each end of my 20 gal betta tank and they dont seem to mind it at all. And yes you can have more then 1 betta In the same tank it’s called a sorority look it up 😉 Bonuses part, my kid killed his tank and I had to completely restart it bacteria and all. having the 2 sponges per filter i was able to transfer a sponge from my established tank to the new one to help jump start the bacteria
Great sponge filter may never change
