Good value on cycling kit

I picked up one of the Aquarium Cycling Kits during a weekend sale, mainly for the Ammonium Chloride Solution. It was a good deal, saved me a bit compared to buying everything separate. The kit had everything I needed, and the instructions were clear enough. Shipping took 5 days to reach Denver, which was fine. Overall, I feel like I got good value for what I paid, and my tank is cycling along nicely. Pretty happy with it.

Consistent results, as always

Another solid order from DrTims. I've been getting my Waste-Away Sludge Busting Bacteria here for a couple years now, and it always does the job. My pond stays clear and healthy, even with all the koi. Shipping was quick, got here in about 4 days to my place in Florida, just like last time. It's why I keep coming back, can always count on them for my pond supplies.

One and Only works great!

I used the One and Only Nitrifying Bacteria for my new freshwater tank cycle, and wow, it worked so fast! My water parameters were perfect in less than a week. I'm definitely buying from DrTims again and telling all my aquarium friends.

Hey, I'm thinking about getting some of the One and Only bacteria for my new tank. Do these guys ever have sales on it or is it pretty much full price all the time?

M Mike G. 3 months ago
Yeah, they definitely do sales. I saw a pretty good discount on One and Only around Black Friday last year. Also, if it's your first order, you might get a little intro discount.

They run sales pretty often, actually. I think I got 15% off some Waste-Away stuff a few months ago for a spring sale. Keep an eye out especially around holidays.

Does DrTims ship pretty fast? I'm in like, Texas, and I want to start cycling my new tank ASAP. Just wondering what to expect for delivery times.

From what I remember, I got my order in about 5-7 days to Florida. It was pretty standard shipping. If you're really in a rush, maybe check if they have any expedited options, but the regular one was decent.

I'm in California and it took about a week for my last order to arrive. It wasn't super fast but not super slow either, just average ground shipping usually. They do offer free shipping if you spend enough, though, which is nice.
