Massive StarReef Salt, 6.7kg For Aquarium Ocean Reef Pro Marine Saltwater Coral Premium for Fish Tank

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 = 420Mg = 1400dKH = 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 KitPH = 8.3Ammonia = 0Nitrite = 0Nitrate = 0

Not much I can say to be honest, it’s marine salt!

Have just purchased another bag of this salt. Seems good quality and the corals open up nicely after a water change. Well worth the low cost.

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.

It works very well. Happy Coral

Good salt. No issues to reportGood service.

Dissolved well. Will see how it performs in tank. Couldn’t reseal the bag after open.
