## Questions & Answers

**Q: can i use this in tropical tank to treat bacteria in general . thanks**
A: Hi, the short answer is yes.
But please bear in mind that adding salt to fresh water is the same as giving yourself a salt bath and will act as an irritant to your fishes eyes etc. Hope this helps.

### ⭐⭐⭐⭐⭐ Perfect 👌
*by M***K on 10 May 2026*

Does the job and seems of high quality. Dissolves easily. A bit cheaper than most on the market, will buy again.

### ⭐⭐⭐⭐⭐ levels of various elements pretty much as advertised
*by R***D on 2 February 2018*

Disolves very quickly, levels of various elements pretty much as advertised. Tested Ca, Mg, KH/CH, using Salifert KH + Alkalinity Profi-Test Kit using R/O water as base: Ca = 420 Mg = 1400 dKH = 10 (Bit higher than advertised but exactly what I need due to Carbonate usage) PH, Ammonia, Nitrite & Nitrate tested using API Liquid Saltwater Marine Master Test Kit PH = 8.3 Ammonia = 0 Nitrite = 0 Nitrate = 0

### ⭐⭐⭐⭐ Good price.. instructions would be good.
*by G***E on 13 January 2018*

No information for this brand on the internet so was weary about buying it but found it dissolves easily and corals seem happy. Would have given it 5 stars but there is no mixing instructions so was trial and error. Found around 9 tablespoons to 10 gallons gives around a salinity of 1.023 so it's just a case of adding gradually.
