Common questions about adding One & Only are: “I have fish in the tank can I add One & Only?” or “My tank is set-up and I have high ammonia and/or nitrite can I add One & Only”? or “If I add One & Only can I add fish immediately”? The simple answer to all these types of questions is that you can add One & Only anytime once the tank is set-up and the water dechlorinated. One & Only is completely non-toxic and will not harm fish, corals or invertebrates and so it can be added when fish and invertebrate are already in the tank. Just shake the bottle well and pour. If your system is already set-up and you have high ammonia or nitrite you can add One & Only anytime to help bring the values down faster. If either the ammonia or nitrite is above 5 mg/l […]

How to change water after fishless cycling with DrTim’s Aquatics’ One and Only
Featured Blog Posts
There are two general types of water for your saltwater or reef aquarium: real seawater that you buy at the fish store or get from the ocean yourself and artificial saltwater that you buy pre-mixed from your local store or in powder form (artificial sea salts) and you mix into saltwater yourself. We’re going to talk about how to mix up your own saltwater. It is easy to do but you need a few items and to plan ahead a little. To begin you’ll need to get the following – a high quality sea salt mix, a clean bucket or trash can (one that has never been cleaned with soap or used for anything else), a hydrometer or refractometer and a source of fresh water. A small submersible pump also comes in handy to help speed the mixing. If you are going to be using tapwater you’ll also need a […]
When it comes to the variety of DrTim’s Aquatics products, some can be used together but sometimes they should not be mixed. I am going to sort this out in a quick fashion for you. One & Only Live Nitrifying Bacteria — before adding One & Only Live Nitrifying Bacteria, the water must be free of chlorine and chloramines so use AquaCleanse or First Defense to accomplish this. Make sure to turn off devices such as the protein skimmer and UV-sterilizer, and remove any filter socks for 48 hours after adding One & Only Live Nitrifying Bacteria. Do not add Waste-Away, Re-Fresh or Eco-Balance during the first 2 weeks of adding One & Only Live Nitrifying Bacteria. AquaCleanse — can be used when first filling your aquarium and when doing large water changes (over 50%). While AquaCleanse can be used to temporarily control ammonia in emergencies, it is much better […]
You read or hear from “experts,” that nitrifying bacteria mixtures don’t work so don’t waste your money. That statement may have been true 10 years ago but is not today. I will explain why. But first let me acknowledge that I do manufacture and sell a mixture of nitrifying bacteria. However, unlike every other company selling these products, I have been conducting research on nitrifying bacteria for nearly 20 years, did my Ph.D. on nitrifying bacteria in aquaria and have published my work in peer-reviewed, scientific literature. No other company can make those same claims. So I ask you: whose bacteria would you rather buy? A brand developed by a scientist (who is also a life-long fish hobbyist) who is published, and has been studying and developing nitrifying bacteria for aquaria for nearly two decades, or one of the brands that has a big marketing department behind them? Let me […]
