Professional 15x strength powerful live tank starter nitrifying bioculture, with much fewer temperature and shelf life restrictions than competing products, for rapidly cycling new marine fish and reef aquaria and brackish aquariums, and for recovering from overcrowding or disasters where the bacteria bed has been damaged or when adding new fish. It is also quite useful after re-arranging decorations or performing major maintenance, such as cleaning substrates or biological media to "recharge" the nitrifying bacteria population.

Overview

  • Super concentrated 15X Suspension of LIVE non-pathogenic microbes, specifically formulated to extremely rapidly establish biological filtration in new aquarium set-ups, and to enhance the rate of nitrification in existing systems.

  • Useful for rapidly re-establishing nitrification bacteria in case of an emergency

  • Particularly useful in aquaria with high population densities and when adding new fish

  • Helpful to re-establish nitrifying bacteria after cleaning rocks and surfaces and after use of medications.

    1. Rapid reduction of ammonia, and nitrite.

    2. Prevents “New Tank Syndrome.”

  • Supplied in a proprietary base which provides for maximum longevity

  • Formulated utilizing extensive data compiled by microbiologists.


Description

MicrōBacter Start XLM 15X creates a nitrifying biological filter in marine & brackish aquaria of all types and is particularly useful for new startups, resulting in cycling in about 7 days in most cases, if directions are followed, and no competeing bacteria or nothing toxic is added (please read this whole webpage.) It quickly removes toxic ammonia and nitrite naturally through non pathogenic nitrifying bacterial action. Even though this product is extremely potent, it may be overdosed at up to 5 times the rated dosage during aquarium emergencies. It should be your first choice to remove ammonia during emergencies where the filter has been inadvertently killed or when experiencing overcrowding.

Technical Background

MicrōBacter Start XLM 15X is a highly concentrated, selective complex of live, extremely effective microbes and enzymes that rapidly reduces the concentrations of organic nitrogen - i.e. ammonia, and nitrite in marine and brackish ecosystems, leading to greatly improved water quality and much faster cycling. Use of MicrōBacter Start XLM does not alleviate the requirement for regular partial water changes to help maintain proper concentrations of elements that are vital to long-term health and survival of aquarium inhabitants.

Notes - It is normal that clumps may form in the product and the product and the aquarium may have an “earthy” smell or smell “off” and the aquarium water could become cloudy and the smell and cloudiness could remain for many hours after using. This is due to the bacteria themselves and is an indication of quality and is the reason it is necessary to shake product well immediately before using.

PAWISE Pee Pad Holder * Big size *
Size: Small
You GUYS.....they shipped this damn thing in a 65inch TV box Do the measurements and then think about how big a that damn tv box is....literally it arrived and my husband & kids thought 1000% I bought a new TV. So far the product I am happy with / its a bigger square for those dancing pups. I am using this on a Chorkie puppy. The big pads fit and it latches them. Now the pup has realized he can pop the latches but he cant get the pad cause the lid is ontop . Im sure this is a puppy thing and will pass he got redirected and hasnt messed with it since. day 2 of use. *** THANKS JEFF & employees for the huge ass waste of cardboard LOL **

Perfect for puppy!
Size: Small
I got this because I bought another (cheaper) alternative and the pads were shredded within the hour. This holder has the corners of the pad covered and that was the saving grace. Worth the extra money because you aren’t wasting money on puppy pads that are shredded before they are even used. If your puppy is still set on shredding, make sure to add lots of toys on a rotation (never the same toys everyday) and it helps a lot. Once I did that and changed the holder, no shredded puppy pads!

Misleading size stated in adv.
Size: Small, Size: Small
Absolutely ridiculous! Says 23.5” by 23.5 “. It just barely measures a little more than 19 inches. You have to fold up the 24” by 24” per pad to fit it. I don’t know if my 5 pound chihuahua will be able to use it. A complete waste of money!! First photo shows it in frame - 2nd photo show what is a 24 by 24 pad.

FANTASTIC PAD HOLDER
Size: 28'' X 34'', Size: 28'' X 34''
Amazon Basics Dog Training Pad Holder 28X34. I'll start out by saying I wasn't too sure about it, when I got it. It is awkward to put the pads in by yourself if your short as on each end the sides have to come up together and it’s big, however, I've done it five times alone now and it’s doable. There was no smell, it arrived in perfect condition. My husband was home and we set it up together, I walked into the bathroom to get a soiled pad I had keep to put on it for her to know what to do came back and she had already used it and she’s only four months old. I love it love it love it, it’s not too big, but it’s her home too, and we have it in the living room where we spend a lot of time as we’re retired. When she gets a little older, we will probably move it to another room, but for now it’s staying there. After she urinates, it goes down to a very pale yellow color I have been able to use one pad for all day, however, she does have a pad in a under bed tote in our master bathroom. We’ve had a few guests over and if she hadn’t used it they didn’t even know what it was. I highly recommend it. I have been using pads in an under the bed tote for over 10 years and this is a welcome audition. You won’t be sorry if you have little ones that go in the house.

Very easy to use and clean
Size: 22'' X 22''
Saved my pad training with my puppy. It's firm and easy to clean. It holds the pads well for the most part, but sometimes my dog gets a little crazy and it comes out, but I don't think it could be better. Still give a 5-star!
