Great product, great price
Great product and excellent customer service. My first bottle arrived empty, but the seller sorted it out straight away and sent a replacement very quickly with no hassle. Really appreciate how fast the problem was resolved. Very happy with the purchase and would definitely buy from this seller again.

Mixed reviews.
The mixed reviews and its claims have made me worried about using this. However I put a half measure in. I found in some fish products you can have Armageddon so if in doubt donโt use it or use smaller measurements. I have no fish in the tank yet and Iโve been doing test strips. Fish in two weeks and water checks coming to satisfactory so must play some part. I usually use cycle but water tests for both have been good.

Good product!
Got this as a cheaper alternative to the more expensive axolotyl versions and it has been great. Like people have said it is quite small but it is also perfect as you only add a couple of drops each time.

Quick Start aquarium liquid
It is good stuff but wait 4 weeks before putting any fish in your tank. Plants growing very strong.
User
worth the money
provides your tank with a bulk load of good bacteria to help build a colony against amonia and nitrates / nitrites

Tried and true
Works. It helps to establish the tank over time. Thereโs no instant cure and you cannot get fish or axolotl or anything in a tank with out any cycle. Wait for it to cycle. Use this. It works well. It takes four weeks to cycle.
