Rated 5 out of 5 by from WORKS!!! I was very skeptical about this product even after reading good reviews. I decided to buy it after setting up my new 50 gallon aquarium and letting it sit a week with no fish. Went to Walmart bought enough TSS for 60 gallons and 6 Cherry Barbs, that was on a Sunday. By Thursday I had readings of 0 ammonia, 0 nitrite and less then 5.0 nitrate. This product cycled my fish tank in 5 days. Thank you Tetra!

Rated 5 out of 5 by from Best Bacteria Product Hands Down... I've been using this product for years on multiple new aquarium setups from 20 Gal to 150 Gallon tanks. It has worked perfectly every time with a full load of fish immediately. Zero to very minimal Ammonia or Nitrite spikes with Nitrates appearing within a few days. It works fine with Prime conditioner. Only possible issue I've seen is if you wait to long to add the product and the ammonia is too high already. If Ammonia is greater than about 2 PPM it may kill the bacteria. Forget about the other bacteria products, this one does indeed work as advertised. Highly recommended.

Rated 5 out of 5 by from If tank cycled, Do I need to stop using it? after 1 week, my 30gal tank is ammonia = 0.5 nitrite=0 and nitrate=5. Does it mean it is cycled? Any help appreciated.

Rated 5 out of 5 by from Best on the market!!! After trying other products to start a cycled tank I paid the price for safestart. Yes it is a bit pricey but we'll worth it. No need to wait weeks to cycle your aquarium. After all a fishnets cycle is a boring aquarium. Yes there are many of other products that claim to start beneficial bacteria but they don't seem to work for me. Being a breeder of fresh water angelfish I need a product that works. I have in the past set up 55 gallon aquariums waited about 15 minutes after adding dechlorinator. Added a small bottle of safestart then added 30 quarter body size angels and never had a problem. Tested water daily to be safe and never found ammonia or nitrites. I only use chemical test kits because I found the tank dips are not accurate. So for those of you that are setting up for the first time use this product. You will be happy you did.

Rated 5 out of 5 by from Safe Start best product for a new tank I set up a new 125 gallons tank for Cichlid Peacock & Haps and because I don't like to wait 2 or 3 weeks I just add the TSS the next day with 12 cichlids & wait 2 days and add another 8.4 oz of TSS with the others 12 fish and 0 ammonia 0 nitrite and after 1 week start doing my reg 25% water change, best product for those like me that do not wan't to wait 3 weeks to add fish to a new tank.

Rated 5 out of 5 by from This product is great!!!!! It works really well in our tanks. I would recommend Tetra products for any type of tank. Their products are easy to use, helpful and beneficial to having a tank. Also, Tetra sent reminder emails when we first started and registered to remind us of different treatments to use. It was nice, helpful and really great having that extra notice. I like these products!!!!!

Hello, I just started a new aquarium and basically used all your products at once: aquasafe, safestart, filteractive and easybalance. Is this a mistake? Should I use them sequentially?

Asked by: Al from London
Essentially, you want to use AquaSafe and SafeStart/Filteractive for sure. Easy Balance you would wait on until the tank has been set up for a month or more. Also, don't add the SafeStart/FilterActive until you have fish in the tank, or it will simply die off. You add that at the same time you add the fish. BREX

I have a high nitrite reading. My tank is 5 weeks old. Can i add safe start to help my fish feel better and lower my nitrite issue. My fish all seem happy at the moment. Thanks

Asked by: Mandyfishfish
Yes, as long as the nitrite levels are no higher than around 5 ppm. Very high levels can be toxic to the bacteria as well. You can still add SafeStart Plus, but may need to add some each day for it to be fully effective as some bacteria may be killed off at extremely high levels. BREX

Can I use safe startplus and lifeguard at the same time? We are using it to treat a case of ick.

Asked by: Jason024
No, do your treatment first, with LifeGuard, and then once you have completed the treatment, do a partial water change and place fresh carbon back in the filter, then add the SafeStart Plus. BREX

Can I use TSS with Prime? If so can you advise best practise as there seems to be a lot of conflicting information on the Internet.

Asked by: Jay Silver
Not at the same time, no. It is safe to use TSS with AquaSafe Plus at the same time. However, with other manufacturer's water conditioners, you should wait 12-24 hours to be sure to not cause a die off of bacteria. BREX

Hello, I am a new fish owner and was confused on how much of the safe start I am supposed to use. I have a 5 gallon tank with 4 small fish do I use the whole bottle? Thank you in advance!

Asked by: Megloraine
Congratulations on your new tank! No, for that size tank, you would not have to use the entire bottle initially. Depending on which size bottle you purchase, reduce the amount. So, for example, assuming you bought our smallest size which treats up to a 20 gallon tank, we would recommend using only 1/4 of the bottle. There is no danger, however, if you use the entire bottle, you cannot overdose it. It would just provide you with some to add later on, perhaps after a water change or if you have to treat the fish for disease at some point and need to boost the biological filter. BREX

Hi I have used, Aqua safe and safe start all in one go.Can you tell me have I done wrong? Also I have left the tank a few days before adding plants and a filter. I haven't added any fish though, is all of the above OK. Many thanks.

Asked by: Steve 12
Thank you for your support of Tetra products! Generally, you want to add AquaSafe as soon as you add water. However, it is best to wait until you add fish before adding the SafeStart. The bacteria will have starved off by the time you add fish now. We would recommend adding some more at the same time you add your first fish. BREX

I am changing the canister filter on my 36 gal planted tank to a new filter. Can I "seed" the new filter by adding Tetra Safe Start into the canister?

Asked by: Bob K
Thank you for your interest in this product! Yes, you sure can! Just be sure to start up the new filter immediately after adding the SafeStart Plus to it. BREX
