Did the job in my new tank

I bought this to cycle a new 255 litre reef tank. The instructions were very clear and there are a couple of very useful videos on line. I followed the instructions to the letter in terms of dosing and testing and the cycle happened just as should, going through the various stages. Personally I much prefer to use something like this rather than use a live fish which would likely be stressed by the poor water quality during the cycle. One concern I did have was that if you followed the instructions fully it states that the tank would be ready for fish after 9 days. This certainly wasn’t the case and it wasn’t until day 15 the the nitrate levels had fallen to zero making the tank fully cycled. I would suggest not following the 9 day suggestion but relying on the results from ammonia, nitrite and nitrate tests. However I was still happy with a 15 day cycle so would use this again if I ever start a new tank.

My go to for all my new tanks and established tanks

This product is great for those not patient for a full cycle.Product is great if you want to introduce fish and running a fish only system.If growing corals I recommend using it but also doing a full cycle as the lights can cause a very tough ugly stage

Works well, did the job.

I've always been a little worried about using chemicals in the tank, but this stuff was great, along with the ammonia it cycled the tank very quickly, haven't had any problems so far, it's been a week with the fish in and still all readings are as they should be, did my first sand clean and water change today and all is good. This stuff works.

Not convinced...

I have added this to my tank as per instructions and correct dose 4 weeks ago. Currently my tank has reading for ammonia and nitrite but has not completed the nitrification cycle as it doesn't have any nitrates.Don't think i would have purchased this had I known the outcome.
