is it bad that instant ocean salt takes 4 full cups to mix up 5 gallons of water?

I use a 30gal mixing tank with a pump and heater, I always use the same cup to add the salt which is about 500ml, I add one scoop for every 5 gal of water to start, so I fill the tank up to about 25gal and add five scoops, turn the pumb (ocean runner 3500) and heater (300W @ 80*F) on and leave it for about 3 or 4 hrs. When I come back I check the temp & salinity (1.026 target) and add salt or water to balance things out, I usually have to add a little more H2Ocean, maybe a scoop or less to get it where I want it then I let it mix for a few more days and re-check, it usually doesn't change.

Correct, that's why I said 1lb to 11 litres (10.962 to be exact) and it mixed to 1.030

cyano
 

i'm not saying that you won't get cyano,but other people and myself had a huge spike in cyano when we used h2ocean-and now that i switched away,my cyano is almost non existant

My apologies koresample, I misunderstood what you said in your original post. I'd be curious to see if other people report excessive cyano as well. So far all I've noticed is that it has a very high calcium level. Mine shows around 480ppm when mixed.

I use this salt without issues.

I used it for a year and a half without cyano. My tank si gorgeous. Happy, colorful corals - SPS, LPS, Zoas. I think it is a good quality salt. Not sure why some have problems, but it also depends on what else you are doing, ie: balling, dosing, supplementing, etc.

Funny, I switched from the H2Ocean to IO a while back when I couldn't find the H2O, I had a huge cyano bloom about a week after changing...I switched back to the H2O about a month later and no cyano since....

Also I had noticed that allot of people in my area were all experiencing cyano blooms around the same time...environmental, water source??? I don't know, I just thought that was a weird coincident.



I'm back on the H2Ocean diet again and am happy.

yup .....2 1/2 years and FTOTM on H2Ocean:wink:

Higher Phosphates in the water a few months back
