Biologically Established Active Sponge Filters
If you are putting the filter in with new-born fry
or a tank that is 5 gallons or less, then the 50ppi
is the best choice, otherwise, the 15/30ppi filters are a better
deal for a much larger size.
These have established colonies of nitrifying bacteria and other
micro organisms that occur in a balanced tank. The bacteria survives
shipping quite well, but faster is better when deciding on the shipping
method during checkout. If the filter freezes, the bacteria
may be killed so pay attention to the weather, here and where you
are. If it freezes, it is at your risk.
It is very risky to order when night-time temps are below 0 F. We
are in a potentially very cold area of the country (zip 14760).
The filters vary in size and shape within the
range listed. All of our Active filters are the "Internal
Weight" filter version.
We have too many filter types to have them all in an "active" version
and this type is easy to ship without water leaking from the bag.
These are "established" in our disease-free aquariums. Read
about our process to eliminate diseases here.
This assures that no pathogens are transferred to your fish.
This is safer than using a filter out of your own tanks, since few,
if any are disease-free. These filters have been run for about
a month in our super healthy tanks to insure the nitrifying bacteria are well established
within the sponge.
If you do not see a box with Tabs below it means
your display is too small for this feature to work. For this additional
information you should view this on a device with a larger display.
When you receive these, make sure to add any water in the
bag to the tank. Do not worry about it being dirty. It is full
of nitrifying bacteria and you do not want to throw this out
or siphon it out with a water change until the tank is fully
Setting Up Filter: Run an airline to the lift tube. Insert the airline into the hole in the top side of the lift tube and thread
it to withn 1/2" of the bottom. Then insert the bottom of the lift tube into the hole in the sponge. You can put the filter into any part of
the tank. If it floats, genetly squeeze the air out of it.
Some people cut these to fit inside of power filters. That will work if the fit is tight, but if
water can travel around the filter instead of through it, then that is what the water will do
and it will not be as effective in establishing your aquarium.
We are not fans of "fish-less" cycling. It seems every time a customer is having trouble
cycling their tanks with our filters, it's a "fish-less" cycle. It's possible some additive in the ammonia
they're adding, is interferring with their test kit readings or is simply doing something to the nitrifying
bacteria. Either way, if you add one of our active filters, your tank is ready for fish. Forget about adding ammonia

|Great product. I was having issues with ammonia and
nitrite in my newly set up 75 gal and within 2 days of
attaching this sponge filter to the intake of my
canister filter(not the way they recommend using it,
but it worked) both ammonia and nitrites are at 0.
Highly recommend this product if you are wanting to
quickly cycle your aquarium. Plus they sent a nice big
bag of beefheart flakes for free. |

|This worked in a week. Amazing. The best thing
I've done for our fish. They also love the free
sample of brine shrimp flakes. Thanks AngelsPlus!|

|I was struggling cycling my tank. After a month of
frustration, I deduced to order one of these. Guess
what, instant cycle. Within 24 hours, I was having
nitrates. Two weeks with the filter, and everything is
perfect. This is the way to go!|

|Why are so many promoting fish-less cycle when this
filter works 100 times better? I'm telling
eveyone, this is way to go. Mine worked perfectly.|

|I was struggling big time getting my tank to cycle and
I heard about these so I figured I'd give it a
shot. Well, 24 hrs later, and the tank is now great. I
couldn't belive it could cycle that quick!|

|This filter does NOT cycle aquariums. All it does is
cloud the tank with fish waste. I ordered one and spent
about $20(shipping), and the water was so dirty, the
ammonia actually spiked.I am completely dissatisfied
with this product and I will not be purchasing anything
from angelsplus again. Also when I placed my order they
claimed they would send me a sample of food, which I
never recieved. |

|After treating my 55 gal tank for Camallanus worms, I
struggled to get a cycle going. It was extremely
stressful with daily small water changes to keep the
ammonia from becoming toxic. I stumbled on Steve's
website and immediately ordered one of his active
sponges...I figured I had nothing to lose and
everything to gain. By day two, my tank parameters
were perfect and my fish very happy! |

|I used the filter for my 36 gallon tank and left if in
for a couple of weeks. I decided to put it in my 5
gallon tank that I never could get to cycle. It has 2
corys and 1 betta. In 24 hours I have no ammonia and
nitrites and I finally see some nitrates! I wish I knew
someone close by I could pass this filter along to when
I'm done with it! It's almost like magic! I am

|Best money I have spent for my aquarium! I don't
think I ever had any nitrites! Fish have done well. I
added them a day after putting in the sponge. The
sponge is a little large and not so pretty in my tank,
but so worth it...besides the sponge will be coming out
soon. I intend on putting the sponge in my smaller tank
next to help it cycle. Customer service is great too.
They reply to emails!|

|Best aquarium investment ever made! I was stuck in high
nitrites and by day 2 this had straightened it out!
Customer service is great too! Thanks!|

|Very good! We got the filter on Saturday and
tank was cycled on Sunday. We also got
Sunday. We have not got fish more
than 7 weeks
because the ammonia and nitrite
was to high until
we found this product. I
wish we found this sooner.
