    I highly recommend this product. A couple of months ago I had a catastrophic filter failure and effectively had to restart the cycle in my tank, but this time with 16 residents.

    Ammonia levels soared, despite trying nearly every bacteria aid product out there, and this continued for 2 months (lots of pwc, more chemicals that I care for). 2 weeks after starting with Tetra Safe Start I have my weekly average ammonia level down from 35ppm to 0ppm and no more nasty chemical additives.

    Fantastic - a total must for new or uncycled tanks!

    Worked for me in two tanks.
    1. Set up tank, fill with water (make sure to use a dechlorinator, such as Tetra Aqua Safe)
    2. Run filter/s, pump/s and heater/s for 24hours. This isn't just to make sure that all work OK, Tetra have said that Safe Start should be used 24hours after using a dechlorinator product.
    3. Lightly stock with fish.
    4. At the same time as adding fish, add Safe Start. Shake the bottle vigorously beforehand. The water will go cloudy. This is normal.
    5. Feed fish lightly for two weeks.
    6. Don't do a substrate clean/partial water change for 2 weeks (unless you've done something wrong and you have a big Ammonia or Nitrite reading after 1 week)
    7. After two weeks you should have readings of Ammonia 0, Nitrite 0 and a reading for Nitrate. The reading for Nitrate is good (as long as it isn't excessive) as it shows your tank is cycled/cycling.
    8. Do not immediately add more fish after those 2 weeks. Do your normal weekly water change for a couple more weeks at least, all whilst taking water readings. Allow the filter/tank to mature further.
    9. When you do add fish, add a small number at a time. Adding too many could result in the filter not coping and your tank could possibly start cycling again.
    10. It can take 6 or so months for a tank to be fully mature and stable. So don't ruin your hard work after a successful start by immediately fully stocking with fish you want. Take it slow, or there is a very, very good chance it will all go belly up.

    Oh yeah, couple points for potential fishkeepers.
    1. You can't overdose with Safe Start. I pretty much double dosed in the two tanks I've used it in. It's not a chemical, it's bacteria, so overdosing (IMO) can only help.
    2.

    I started a new tank with a few hardy fish. After six weeks there was still nitrite at unacceptable levels. I use Safe Start and 24 hours later nitrite was at zero.
    I have occasionally had a small nitrite spike after changing filters and a small dose of Safe Start has rapidly reduced the nitrite to zero.

    I became aware of this product through an online forum. I have a tropical fish tank and although the tank appeared to have cycled several weeks previously I suddenly had a large ammonia spike. The tank is only 45 litres but I used the entire bottle over a period of 2/3 weeks, adding more with each partial water change. The ammonia levels dropped after this time. This product is great for people like me who have an established tank and are having "water issues" or for those who are just setting up. Tetra recommends cycling a tank using Safe Start with only a few fish to begin with but as I have only 6, it was the ideal product. Note; I had fish and ammonia before I used Safe Start - the bacteria in the bottle need something to feed upon.

    I bought this product to cycle a new tank, and had very little luck with it.

    I bought it after reading some comments that they had their ammonia and nitrite levels at 0 after a few days, well, in my tank I patienty waited to 2 weeks now and Ammonia is at the same level (3) and there's been no nitrite readings ever (it's on 0) and no nitrates so there's been no bacteria action at all, it seems.

    After adding it there are lots of cloudness (normal) and lots of seemingly dead debris floating in the tank (not normal).

    My only guess is I've had a bad batch (I'll be sending my bottle back to Amazon) with dead bacteria inside.

    Will try other products instead as this was, unfortunately, a disappointment and a waste of time.

    Excellent for new tanks. I use a little bit every water change too just to keep everything in the tank healthy. I have a small tank and do weekly water changes (30%) to keep the water clear and the fish happy. Use with AquaSafe every time. If you have a childs medicine syringe (the one without the needle!) it fits perfectly in the bottle opening and ensures you put the correct amount of liquid in the new water.
