Penn-PlaxCascade 1200/1500 GPH Canister Filter Aquarium Bio Sponge Replacement; 1 Pack

With above ground pool pumps/filters sold out everywhere this Covid-19 summer, we got the Penn Plax Cascade 1500 filter pump for our 300 gallon stock tank that we use to cool off in. It arrived in two days at a great price and works like a charm to keep the water in the stock tank crystal clear (we cover the tank at night and also use a floater with small chlorine tablets). The pump is near silent and performs way better for our make-do little above ground pool than we ever expected, though it was designed for aquariums and not pools.

Better then any Marineland equipment. The price is a lot better too. Glad I took a risk!! Have had it for almost 2 months with zero issues and the set up was super easy.

The "used" Penn Plax 1500 I purchased for a great discount was apparently sold as used only because the box was slightly crushed, which in no way effected the filter. The filter was pristine, not scratched in any way, and after googling how to place the biomedia ( the instructions were completely opposite of all I'd ever researched ) it only took five minutes or so to have the filter up and running. I continued using my previous filter in hopes that it would help speed up or reduce the cycling time. That worked perfectly😎 BTW, and by the next morning the water was so crystal clear it looked as though my turtles were suspended in air. I'd actually never realized just what a difference a canister filter would make in my water quality. I usually do a weekly water change of about 25% as a matter of course, and waited for one month before cleaning the filter. Based on the appearance of the bio media at that change, I will increase the timeframe by at least two weeks before cleaning it again, and if it still looks as clean at that time, and my water testing remains at proper levels, I'll increase the time between cleanings accordingly.It was slightly intimidating the first time I turned it off, but shouldn't have been. Only took about five to ten minutes all told to clean, and another five or so to get it hooked back up and primed. I'm extremely pleased with the product and the seller. I would make the same purchase from the seller at anytime I need another filter for a new tank.

This is a great filter system that works very effectively. The bio sponge fits nicely in the tray and when cleaned properly will last a long time. I change mine about every 6 months and clean it every 2 months. I have mine filtering a 45 gallon and the water parameters have remained perfect.

Works great on my 55g cichlid tank. Water changes are far more infrequent.

I have a cannister filter and use the Bio Sponge in one of the three trays. It has performed well and I can rinse it as opposed to replacing it like I do floss pads.

I love the ease of replacing with just using another sponge - easy change out. My tank is so clean that I have noticed colors in my fish I never saw before.. This is obviously making a difference and I am gong to continue using this product as well as recommend it to others. I thought my filter was doing a great job, but adding this sponge has made a great looking tank even more awesome! Thank You !!!!

it does what its made to do keep tank clean been using it for many years im surprised i can still find product

Perfect!
