We would recommend you set the tank up and let it run for 24 hours. Use the Aquasafe as soon as you set it up, to remove the chlorine, heavy metals, etc. After 24 hours go ahead and get your frogs. As they float in their bags, waiting to be released, go ahead and add in the Safe Start. You cannot use it at the same time you use AquaSafe, which is why I recommended waiting 24 hours. After about 10 minutes, release the frogs.

You should not need any other chemicals, and the frogs will not tolerate chemicals in any case.

Question

how much safe start plus do I need in my 2.6 gallon tank? Also, when should I add fish?

Set up tank about 4 weeks ago. Added ammonia to begin initial bio filter cycle. Ammonia level is down to 2.0 ppm from 6.0ppm. Nitrite level is 0.0 ppm. Nitrate level is 0.0 ppm.

You can go ahead and add the TSS Plus now. But add a fish to the tank immediately before or after you add the TSS Plus. The bacteria will need a constant source of food once they are in the tank. It will take several days, but they will cycle the tank for you without your needing to add anything else. Do not do any water changes for at least 7 days after you add them.

For such a small tank, you will not need very much. I'm not sure what size bottle you purchased, but probably 1/4 of the bottle will be plenty.

Question

How long to wait accurate results of Ammonia, Nitrite and Nitrate after using Tetra Safe Start ?

I have a 10 gallon tank with 1 platy fish and I've been cycling about a week when I decided to put some TSS on the 9th day. After 4 days I tested my water parameters and it showed 0.25 NH3 0 Nitrite and 10-20 ppm Nitrate. I never saw a spike in my Nitrite and I also did a 10% water change to control ammonia levels down. My ammonia level has always been 0.25 ever since I started my cycling so I was a bit confused about the results I got. So what I'm asking is if TSS is working? and if my results are accurate enough. Would the Nitrate level be toxic for my fish? Because I have another bottle of TSS + on hand if the previous bottle that I placed is not working. If TSS is not working would I do a big water change and then put TSS+? Thanks!

It sounds like you have already cycled the tank. The nitrate is the final stage. Once you start registering any nitrate, NO3, then you are pretty much done with the initial cycling stages, other than waiting for the bacteria to break down whatever remnants of ammonia and nitrite you still read.

.25 ammonia NH3/NH4 is negligible and not of concern. Your kit may be giving a slightly wrong reading for ammonia, or you may not be interpreting the color properly.

You only have one fish; we would not expect to see an ammonia or nitrite spike at all (spikes are higher than .25, at least 1.0)

We recommend waiting one more week, then begin whatever your water change routine will be; i.e. 10% once a week, 20% every other week, etc. Whatever you are planning on establishing as a routine.

Yes, definitely. Safe Start can be added at any time other than when you are medicating or have just used any product that removes or locks up ammonia, including water conditioners. You also would not use it when using an algaecide or water clarifier or if you ammonia or nitrite levels are extremely high.

Hello -
Shew! That is slew of questions. TSS or Tetra SafeStart is a wonderful product which speeds up the cycling process of a tank and also introduces necessary, beneficial bacteria into a tank(which aids in breaking down the toxic effect of biological waste.)

To answer your first question, you would want to add in the TSS no more than 30 minutes before adding in your fish. As for subsequent dosings and stocking, you will need to closely monitor your water quality. If you see a spike your nitrites, add in another dose of TSS and hold off adding any more fish until your nitrites and ammonia are back down to a "safe" level. Ideally, you will only do a 25% water change (using a gravel vacuum) every 2 weeks. For the first six weeks, you may wish to add in more TSS as a precautionary measure after a partial water change.

Best of luck!

Always use Aqua Safe, yes. If the tank is overall healthy, water quality parameters are good, and the water change is small, less than 25%, you should not need TSS. If you are doing large water changes or have cloudy water, water quality issues, starting a brand new filter system, adding fish, anything like that, then yes, use the TSS.

You cannot harm the system or the fish by adding TSS regularly though. It is always beneficial to add it.

I need to know what levels of ph and other chemicals are safe for safe-start. I have 6 fish already in and I have very high ph. 7.8-8.0. I just put in a bottle of safe start plus for my 36 gallon and i either think that they have not blossomed or they are dead what levels of ammonia does it need. Any answers will be greatly appreciated and if possible could I get them in a hurry.

pH will not affect TSS Plus. The bacteria will be affected by any chemical that locks up or removes ammonia, including basic dechlorinator. You also would not want to use it at the same time you are medicating a tank or using an algaecide. Essentially, it is best and safest to not use it within 24 hours of any chemical.

They don't require ammonia levels to be present in the tank in the way that I think you mean. The container they come in has a special solution that feeds them until they are placed in a tank with fish. Even one fish in the tank will be producing ammonia, and hence, feeding the bacteria. If you have 6 fish in your 36 gallon, they are getting plenty of ammonia.

I'm not sure why you think they are dead or have not "blossomed". As they are bacteria, they do not work like a chemical. They will cycle a tank over a period of two weeks, and you may get readings of ammonia or nitrite up to 1.5 ppm during that time, as a part of the process. Those levels are fine.

Is it ok to use Safestart 10 days in to cycle?

I am 10 days in to a fishless cycle and I'm thinking of using Tetra Safestart instead. My current water parameters are 2-4ppm ammonia, 0 nitrites and 0 nitrates with a ph of 7.2. Can I do some water changes to get ammonia down than start cycling with Tetra Safestart and adding a few fish? After I change the water I will be using Prime and letting the tank rest for 24 hours. I have a 29g tank.

Yes, you can. We would recommend exactly what you are suggesting doing. Do the water changes, get the ammonia down, add a couple of hardy species of fish, just one or two total, depending on the size of the tank, and add TSS Plus. Make sure to wait 24 hours after the last water change, before adding the TSS. Do not use it in conjunction with Prime. Prime will greatly reduce the effectiveness of the TSS.

Question

How much Tetra safe start Plus for fishless cycle?

Hello, I am trying to do a fishless cycle. Now I know that adding one 8.45oz bottle of TSS Plus in a 75G fishless tank with a 4ppm ammonia will be useless since it is going to overwhelm & kill all the beneficial bacterias in TSS.
My question is: if I have 4ppm of ammonia, would it help to put 2 or 3 bottle of TSS (3x8.45oz) to make sure their good bacterias are not overwhelmed? I want to stay at 4ppm of ammonia because I want to build a strong bio-filter. Thank you!

According to our product manager, you can go ahead and add the entire bottle, and one bottle should be enough. It will take a few days for the bacteria to kick in, but they will be fine. They will need a constant food source of course.

You would need the test kit. They typically come with such a chart.

Basically though, for ammonia and nitrite, anything more than 0 is not good. If it is 2.0 ppm or higher, it is toxic. For nitrate, you want to be around 0-10 ppm for freshwater, and at 0 for saltwater.

pH, alkalinity, etc, will vary according to what kind fo fish you keep.

TSS Usage

I've set up my tank (5 gal.). I've put in the Aqua Start and added my fish several hours later. I waited 24 hrs. Can the TSS be added to the tank now or do I need to mix it with water before adding and should the new water be treated with Aqua Start first? Yeah, I know I'll have to wait another 24 hrs first.

Question

Why do you add an entire bottle of TSS on start up of a new aquarium?

Just read an answer that you said there was no exact measurement of TSS since it is cultured bacteria. The bottle said to empty the entire contents in the new aquarium up to 40 gallons. Since I have a five gallon tank why wouldn't I use 1/8 of the bottle or in this case 12.5 ml to start.

You can, if you wish to do so. We recommend using the entire bottle because once you open the bottle, you shorten the shelf life to just 6 months. However, if you cap it tightly, store it properly, you can use more each time you add a fish or get cloudy water, etc. Using the whole bottle would not be an overdose though as it is not a chemical, but aerobic bacteria that establish your tank and keep it healthy. You cannot have too many of these little guys in your corner, so to speak.

The smell is from a high level of ammonia or in other words, fish waste. Replace over half of the water in the tank, and mix up Aquasafe into new water. Slowly add it to the tank to keep from shocking the fish (do all of this over about a 30 minute period). Make sure the water temperature is similar to the room temperature. Wait 24 hours and add the Safe Start. You don't add the TSS at the same time as the Aqua Safe because the Aquasafe can harm the TSS.

Also, only feed once a day for the first month, 1 to 2 pieces of food per fish.

To answer your original question...yes...and no.... You can add fish without SafeStart, but you have to add them at a very slow rate. We usually recommend 1" of fish per every ten gallons of water for the first 2-4 weeks and minimal feeding to avoid problems with ammonia and nitrite.

With TSS, you can add it a few minutes before you add your fish, and fully stock your tank if you wish. The ammonia and nitrite will gradually rise to around 1.0-1.5 over a period of a week, and go back to 0 by the end of the second week, causing no issues with the fish, and fully establishing your tank. You can also add a few fish at a time, but not as slowly as in my first recommendation, and suffer no ill effects.

No, you do not want to mix it with a medication, the medication could definitely harm the sensitive bacteria. You want to wait until your treatment is done, then do a 25% water change and put fresh carbon in your filter to help pull the remaining medication out. Wait another 24 hours after this, and treat with TSS. As long as you did not add a lot of fish, the cycling should progress slowly enough that you can wait a few days before using TSS. If you are already registering ammonia, it may be better to sacrifice the one fish, and add TSS, as long as the ammonia is still low. Keep in mind, TSS is NOT a chemical, so it takes several days to start seeing results, and approximately 10-14 days for it to cycle a tank. Without TSS, it takes 4-8 weeks to cycle a tank.
