Amazing product!! My tank was cycling for over a month and no changes, my ammonia 0ppm, nitrite super high and barely any nitrate, and I was using brightwell florin bacter 7 which is great as well but for some reason wasn’t working for this bigger tank. So I did some research and it said I could just substitute the florin Bacter for the micro bacter start XLF since they’re the same brand and are compatible (do your research) so I did and after 4 days dosing it my tank was ready and no nitrites at all!! It was like magic. I recommend this to start cycling the tank since it’s so strong and then continue after water changes with the Florin Bacter7 which is what I’m doing and it’s going great so far. Also keep both in the fridge. One think I must add is that for some reason I thought the bottle was going to be bigger because of the picture they display but it’s still enough because it’s concentrated and it’s only to use once in a while. I also use it when I have ammonia in my nano tank I dose it for 2-3 days and it boosts the nitrifying bacteria 🙌🏻 love it and will buy again and again.

This is the best quick start for bacteria that i have used. I’ve tried all the other brand names that everyone is aware of. My tank was cycled in a week. Will be my go to from now on.

So I moved from a 29 gallon to a 75 gallon and I only brought one decoration and a sponge filter from the 29 gallon. I noticed after 2 days my ammonia was converting but I honestly can't tell if its because my bacteria survived or because this is a great product. Nonetheless, I'm sure it aided in the process. I kind of bought this cause DrTim's was out but I'm sure it actually does work. Also the cap had a little hole so every time I shook a little would come out. Didn't affect my water clarity or anything. For the price I think it's alright.
