In fact it has the potential to act as a flocculent, binding any soluble organic polymers and orthophosphate so that it can be easily removed by the skimmer thus contributing to the quality of the water.

As people have commented negatively on the aesthetics of this occasional deposit we have now changed the supply of the additive so that this is no longer present.

As far as the mix ratio is concerned - the actual mix should be 39.6g / lt whereas a check that we made with some Tropic Marine Pro required 41.2g / lt to give the same salinity.

Remember that the mix is done by weight/volume of water and so to measure in cups per gallon is very rough as it depends on how dry the salt is and how fine/compacted it is.

The correct mix according to my calculation is 1lb of salt to 3.025 US gallons of water to get a salinity of 35.5ppt or an SG at 25C of 1.025.

Remember that the most important thing is how good the tank looks and how healthy the corals appear to be. Do not fall into the trap of the pilot who flies into a mountain because his instruments tell him he is high enough to miss it - use your eyes and observe the differences in your tank.

Thanks for the great reply, you answered all my questions. And my tank is looking great.

Wow lots of great info in this thread, I'm going to switch over from Instant ocean to H2O.

I made the switch. running my 135 & red sea on it. Colors of corals are awesome. Of course im using Zeo too

Ive been using H20 for about a year now and my corals always respond well after a water change.Coral colours became richer,especially the reds.
I was a pleasantly suprised that i was able to use the salt without any calcium,Alk or magnesium additions as i had to previously with another well known salt.

I know,I know this is an old thread but i'm thinking of switching salt from Reefer's best to this H2o salt.Reason is i can get H2o localy and the Reefer's best i have to order.
So i wanna know if everyone is still happy with this salt.
Thank you
