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.
There are likely hundreds of species of nitrifying bacteria in a
tank that has been "established" for over a year. This is why those
commercial "starter" products with a dozen or so species, don't work
very well. Our filters contain all the species in balance and
is why they work so much better.
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, so pay attention
to the weather and to where you choose to have them delivered. Sitting outside after
delivery is generally not a good idea.
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

|Wanted to say THANK YOU for providing a wonderful
product. We were having a really hard time getting a
ten gallon tank with only one male betta fish to cycle.
Only 48 hours after adding this sponge filter our tank
"cycled" and has maintained perfect water
perametersi ever since. This is the rare product that
does exactly what it promises. Absolutely recommend!|

|Hello, I just wanted to send and email to say thank
you! I received 2 of your active filters on Thursday. I
made a very newbie mistake and changed to many things
and destroyed my cycle. I have been struggling for two
months to get it back on track. Daily water changes,
ammonia never going down, never seeing nitrite or
nitrate. I am in tears right now it is Sunday and my
tank is cycled. I found out about your filters from an
old post in a fish blog. I cannot thank you enough. I
am extremely happy with your product and I will be
ordering more for future tanks. |

|I just moved half way across the country, and took 20
angels, 5 discus and 13" and 14" Oscars.
Unfortunately, my filter media was lost, and after 5
days in coolers my fish were going into uncycled tanks.
I am so grateful these were available. Thank you!|

|It has been 6 weeks since I placed my biologically
established active sponge filter in my new 10 gallon
fresh water tank. Prior to this, I have struggled for
months trying to cycle my tank and lost many fish.
This is the first time ever I have successfully cycled
my aquarium. All levels are normal and my fancy guppies
are healthy and thriving. Highly recommend this

|Despite usually having active tanks that I could use
for seeding, I still get these active filters if I want
to start a new tank. I like the quality and size of
the sponges and they cut the new tank cycling time down
to days instead of weeks. I add a fish or two
immediately and stock slowly to make sure everything
remains in balance and haven't had a failure yet.|

|I was given a tank that was 8 years old and has had 3
different owners and none of them could keep anything
alive. After a decon(H2O2)of all items I started to get
tank together. After 4 weeks of ammonia with no end in
sight I bought this.Test results before PH 7.2 Am 2
Nrite 0 Nrate 0. 22 hours after filter, Ph 7.2 Am .25
Nrite 1 Nrate 5. WOW what a difference! Outstanding. No
food sample though.|

|Thank you for this unbelievable product! My tank had
been cycling for nearly 3 months with high ammonia and
no end in sight. I tried so many different things and
none worked. That is until I found Angels Plus. Within
24 hours of putting the sponge in my HOB filer, the
ammonia levels began dropping. After a few days,
ammonia levels were 0 and I had nitrates. You can't
go wrong with this product!|

|EXCELLENT. THIS IS THE CURE!!! If your even
considering this or having issues with the cycle, spend
the money, put this in and your done. I have three of
them going at all times! Perfect water quality with

|Thank you! After 6 weeks of unsuccessful fishless
cycling using other products, installed active filter
from Angels Plus and within 12 hours, ammonia levels
were down and seeing nitrates for first time! Will be
stocking tank within days. Great product, wish I had
known about sooner!|

|Thank You !!!!! I have wasted probably over a 100.00
dollars in last few months with different filters,
media products and chemicals , to help get my nitrates
in line and clear my tank up. I received my sponge
today , did a 30 % water change added sponge and the
sponge water , tank is looking GREAT !! and nitrates
already dropping !!! best 10 dollars i have spent in a
long time |

|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!|
