I purchased 1 Crypt Undulata, which has been in my dirted tank (new setup) for about a month, and it is doing well! It arrived healthy and only had 1 or 2 leaves melt initially (this is to be expected as it needed to adjust to my water parameters). It has doubled in size and looks great in my new low tech tank.

I have run the green coarse sponges for years and have really enjoyed them. I feel that the black version looks great on tanks with black backgrounds. The included Easy flow kit makes the filters very quiet as well.

I have run the green coarse sponges for years and have really enjoyed them. I feel that the black version looks great on tanks with black backgrounds. I have used the fine sponges in the place of box filter in some of my mulmier tanks. The included Easy flow kit makes the filters very quiet as well.

These have always kept my Amazon swords big and dark green. I tried another brand and turned out to be a waste of money.

Was using the aquarium co op 40g sponge filter in my 20 long and had TWO tetra pumps to power it! The flow was so slow, but with the dual aquarium co op pump and cutting the larger sponge filter in half to use on two filters I’m shocked at how great and even the flow is with both filters and I didn’t have to mess around with air tube splitters or anything! I also love how you can turn the filter on and off with a button instead of unplugging it and you can adjust the strength of the air!

I’ve owned my single line air pump for a twenty gallon long aquarium since December and have had three power outages that didn’t last more than fifteen minutes and I was home for all three and the pump didn’t miss a beat. Plus it’s super quiet. I’m starting a seven gallon rimless aquarium the middle of July after vacation and I’ve already purchased a second pump for it. Highly recommend these pumps.

I was hoping it would be big and it is! My Parrots and Angelfish sure SOOO happy!!!

In my 40g breeder I have CPDs, neon and ember tetras, a trio of sparkling gouramis, some guppies and a hella chill betta. They ALL love this food! Even my Scarlett baddis will carefully stalk the slow moving particles, though I haven’t seen them actually eat it. Either I look away at the right moment, or their Pygmy Cory cleanup crew also loves this.

Seriously—- this stuff is great. On the rare occasion it makes it to the ground in my big tank, their Cory cleanup crew inhales it.

So far, so good... I've only used it once, but it worked great when collecting Sterbaii eggs... Hopefully my Venezuelan Black Corydoras are next species to go... Thanks again... Keep up y'alls awesomeness...!

I received my new Black Easy Flow Sponge filters today with the fine sponge. Immediately took one out rinsed it off and set it up in a tank. Folks are going to love these, first off I liked the green, blended into a tank nicely. But this black is scrumptious to say the least, very nice. As for the fine sponge, I know many have asked for it especially for shrimp and fry or small fish tanks. You all will really like this sponge, it's not cheap fine sponge it's really nice fine sponge. I kind of expect the first run of these to sell out, so. . . get yours while they are in stock!!!

Absolutely love this makes hatching so easy. Totally worth the money.

These coarse sponge pads are a much better alternative than replaceable cartridges for HOB filters. Just lightly rinse the dirt from the sponge once a month. I have some used for over 3 years. Time to replace them.

This makes feeding my fry so much easier—I find myself feeding them even more now! It literally takes 2 seconds to unscrew the cap and squeeze. I’ve also noticed that the adult fish love it too!

FYI: I ramble on the same thing in the video if you'd prefer that to the wall of text.

I like this food, I so badly wanted my fish to like it, but alas, they barely eat it. I love how it floats in the water and I think it is better at triggering hunting responses in my fish because of how it moves mid column.

It has the same great simple ingredients as the magic small fish feed, but in different quantities, yet my fish like the small fish feed over the community pellet and I think it's because of the hardness of the pellets.

My fish get really excited when it hits the water, but they nom on it for a bit then spit it out. After a while they just start ignoring the pellets floating around. In the hand the pellets have the same hardness feel as some other competitors pellets I've tried, which my fish also do not eat. The pellets aren't huge but I think their size exacerbates the problem of the pellets being too hard for them.

Could it very well just mean my fish are picky? Yes, but I'd keep it in mind if you have fish like mine who prefer soft foods.

So happy with my Betta Community tank; I couldn’t have done it without Aquarium Co-op!

Okay maybe not since sliced bread, but shrimp and my kuhli loaches love these shrimp caves. I have 4 in this tank and they all get used.

Magic Nano Feed, is good for Platies of all sizes, and they love this stuff. Glad I ordered another before they sold out.

Ordered this and it arrived within 3 days, the plant bag was a yellow color, hard to see in the video, and had a foul odor, when the plant was being removed it disintegrated during the process. Now the other plant in the order, pogestemon octopus, came in beautiful, no issues and of course everything else in the order came in no issue, first time having an issue with ordering and I’m certain it wasn’t their fault just sucks since it’s a $20 surcharge to order again, but I’m probably ordering this plant again soon to see if it was just a one time thing.

This plant is great in two ways:
1. Does well in the 83F of my discus tank.
2. Doesn’t get the black algae other plants struggle with.
I’m enjoying how fast it grows and how it converts from leafy to a long thin octopus look.
And it’s good in both substrate or floating.
It might very well be my favorite plant!

Easy peasy lemon squeezy to add to my ACO sponge filter. Really appreciate the video explanation. Took me all of 2 minutes to install. Flow has significantly improved and my filter is already looking messy from the additional suction.

I noticed that my Angel fish had paired and spawned. This product was great they are still in wriggle stage but I estimate at least 200 babies hoping they continue to do well.

When I first hatched BBS I used an off brand from eBay because it was cheap. They seemed fine to me. But the brine shrimp were frequently dead at 27 hours of hatch time. My fish still enjoyed them but they didn't jerk around and cause the feeding frenzy. I ran out of those eggs and bought some eggs at a LFS that is a retail partner. Holy cow were these different. The hatch rate appears to be much higher. The BBS are active for much longer and live much longer. I am so glad I made the change. I thought Cory was just hyping his product to sell more. But once again with ACO the hype was real. These truly are much better eggs than the competition. They aren't that much more expensive but are worth way more than the difference I paid.

Had great results new at hatching brine shrimp. Hope it will be in stock soon as I didn’t really want to try another brand because the eggs float at the top which makes harvesting so much more efficient.

These are by far the best sponge filters around, I’ve had several others and these blow them away I have them in my 10G and my 55G

My fish love these! They are well made and worth the money. The jar is actually all the way full of product, good to see! Honest company doing the right thing! Love these guys!
