    From the manufacturer


    No other company comes close to our experience, original research and knowledge about nitrifying bacteria in aquatic systems. We’re not only experts we’re hobbyists, too. Our goals are to help you be successful and have fun keeping your fish.

    Why Should You Choose DrTim’s Products?

    DrTim’s Aquatics is the leader in bringing new, innovative products to the fishkeeping industry, including Pet Stores, Public Aquariums, Fish and Coral Farms, and Service Companies. We strive for 100% natural products and contain the latest in scientific research for making fishkeeping easier.

    Fishless Cycling

    The term “fishless cycling” refers to the process of establishing the nitrifying bacteria in a newly set-up aquarium without using fish which are used in the traditional cycling method. The problem associated with using fish in the cycling period is that normally, when establishing the nitrifying bacteria in a new aquarium, the ammonia and nitrite concentrations can get so high that the fish may die.

    How Our Products Work

    DrTim’s Aquatics offers a variety of products, most bacterial-based. For maximum effectiveness some products should not be added together to the aquarium on the same day. This allows the bacteria in a specific product to work without competition from the bacteria in other products.

    Filtration Media

    Quality media, for each of type of filtration (mechanical, chemical and biological) is important for setting-up and maintaining your aquarium. DrTim’s Aquatics uses the highest standards when selecting our media. We provide a wide range of aquarium media to meet every situation: from our biomedia and activated carbon to our ion exchange resins our products and more you can count on DrTIm’s Aquatics Filtration Media.

Use as directed, when needed, and you'll be good to go.
A must have if you have a need for a ZDDP additive. This won't fix your worn valve seats, leaking piston rings, seasonal depression or gout but it will improve the lubricating properties of a quality oil in a properly maintained motor for your longevity goals.

Buddy filled diesel skid steer with automotive gas engine oil. Used this to help.
We all know that guy who will buy a $65,000 machine and then only service it once a year with the cheapest oil on the shelf from Rural King or some other place with ultra cheap, home branded, questionably quality oil. Yep. That is my good buddy. So I go to the shop a couple weeks back and he is re-filling the skid steer engine with some ultra cheap, totally not to spec, gas engine oil. I question him and he states that it is perfect oil for the machine being 5W-30. I ask him if it meets the SAE ratings for the diesel, he repeats back that yep... it is 5W-30. So I go grab his New Holland book (C232 track skid steer) and look up the oil requirements, then I look at this junk oil, and I try to explain to him the SAE designations on the back of the bottle and the SAE requirements in the book. He looks at me like I have 3 heads and repeats that it is 5W-30, it is totally good. Someone.... kill me please! He has no clue what I am trying to explain. So I couldn't sleep knowing what he is doing, and I ran to Amazon to see if I can at least get zinc to add to the wrong oil and try to help the cam followers and rockers survive this next year. I found this. I ordered a few bottles and had them shipped to his shop, and I explained to him that these need to be dumped in to at least make an attempt in not prematurely wear the engine that likely is worth $20,000 or more! So the real question is, will he actually dump these into the machine, or will he toss them on a shelf never to be seen again? We may never know. But I bet next winter he will once again shop for the cheapest oil on earth to put in a machine that costs as much as some peoples home. He is who he is, you can never change that.

High quality replacement clips. Highly recommend.
I used these when replacing the headlight assemblies on my 2011 Honda CR-V. A few clips were already missing before I even started taking the bumper off, and of course a couple more didn’t survive the job. These fit perfectly and snapped right in with no issues. If you’re missing clips or break some while doing a repair, these are a simple fix that gets everything secured again. Very good deal.
