API QUICK START

The API QUICK START for freshwater and saltwater aquariums is a total game-changer—especially if you're setting up a new tank or adding fish to an existing one. It makes the nitrogen cycle process way less stressful, both for you and your fish. I used it when starting a new freshwater setup, and within 24 hours my tank was safe and stable. No ammonia spikes, no nitrite issues—it genuinely helps establish the biological filter FAST. It's also great to use after water changes, adding new fish, or cleaning the filter. What I love is that it’s super easy to use—just shake and pour. The bottle gives clear instructions, and the results speak for themselves. My fish were active and healthy from day one. This is one of those products you always want on hand. It helps create a healthy environment and gives peace of mind whether you're a beginner or a seasoned aquarist.

Works well to make tap water safe for fish.

This is great for starting a saltwater tank. Water clarity is great. Longevity is good. Concentration is simple and effective.

This is great! I use all the time when changing out water my fish tank.

This is the ONLY THING I USE FOR MY TURTLES to keep they BIOWASTE DOWN AND MAINTAIN THEIR NITROGEN CYCLE. This product works wonders and i highly recommend it. This product is SUPER CONCENTRATED so you only need to use it AS THE BOTTLE RECCOMENDS!!!!! TRUST ME ON THIS!!!!! I have 1 turtle and 2 bettah fish and i use this product for both tanks. ANYTHING WITH WEBED FEET HANDS OR GILLS REQUIRES THE NITROGEN CYCLE and this product does EXCELLENT with starting the cycle and MAINTAINING IT keeping NITRATES AND NITRITES DOWN TO A VERY MANAGEABLE LEVEL and keeping down the SMELL OF AMONIA IF ANY!!!! so anyone with fish or turtles like me..........BUY THIS AND THANK ME LATER!!!! ENJOY

Si, ok

this definitely helped cycle my tank super quickly i really recommend this as someone who struggled with cycling tanks a lot. i gave up so many times and sold everything and then rebought stuff again like a year later and i had gotten this and it cycled my tank in literally like a week- that's crazy to me the ammonia levels were on point i used dr tim's droplets the water ph levels and everything else was very good! it kept the water super clean too (idk if that was this particularly or not) but it's an amazing product and it's really not that expensive! it's super easy to use as long as you follow the directions and it's very accurate at being a quick start!

I have had an established twenty gallon long. Aquarium for over six weeks, from time to time, I have been losing guppies like crazy it's been terrible today. I added two 10 ml of this product it perked up my guppies as a matter of fact my dumbo looked like, he was gonna be the next victim. And this helped his colors back day 2 everyones good 👍 buy it It's a probiotic

Its good to rapidly reduce ammonia

Highly effective Improves water quality by maintaining bacterial colonies Easy to use... Rather than other products. Must to stepup a new tank.. also it is good to add once in month so replenish the bacterial colonies

API quick start ist super, ich benutze es seit etwa einem halben Jahr und bin sehr zufrieden. Ich empfehle es mit gutem Gewissen weiter!

Good product
