Reasonably priced. Worked great and tank was cycled and ready for fish. Tim's website has a pdf with better instructions on how to use this product.

Tims ammonia method. Decided to use this instead of household ammonia (without additives) to avoid dosing calculations. Used to cycle a 5 gallon planted tank.

Bottle has a squirt top to add drops. Comes with a dropper lid.

This stuff is watered down like crazy. Also, the dropper is terrible. Tested it and showed no ammonia, nitrite, or nitrate.

Save yourself the headache and money. Pretty disappointed. Waited another day and nothing.

Found a leak in the old canister filter. Tested the water two days later and there was no ammonia and no nitrite. I use a 330 gallon ibc tote for my water changes.

The complaints about this product seem to be because users expect their aquarium to cycle in a week. Definitely recommend to accelerate the process. Only complaint is that it takes longer than expected.

Oz bottle is way to expensive. I have no idea if it’s effective. It says so on the back in fine print!

If your nitrifying bacteria aren't in a bottle/pouch that needs to be refrigerated, they're probably just worthless dead bacteria. I switched to a different product that i know has live bacteria in it as it smells something awful.
