FOWLR Tank only requires it to be 1.017-1.027 very wide range.

You've been so helpful. Not sure you can figure out this for me, but if I currently have the water in the 68 gal at 1.012 and want to go to 1.017, and have left room to add water, do you have a clue how much salt I should add to get there??

I would say I can add another 10-15 possible gallons of water to fill the tank, and I want to bump the salinity up so I can get some live rock.

Depends on the salt your using I believe. The inscructiions on the bag should give you an idea how many cups to use. But if your mixing it in a small bucket first, then adding it to the tank water, if I guess here, I'd say mix a gallon at 3 times a gallon mix. I'd its still low after that, yiu can always take alittle water out of the tank to add a higher mix again.

Okay, last question I've got the 68 gallon at salinity of 1.018 with a filter running on it. Couple pieces of live rock and 8 cups of substrate from someone running a coral only marine tank added yesterday. When the tank finishes cycling, will I have any problems when I move the other filter, a fluval 305 (I'll run two filters until tank is well established) that is on the 28 gallon with salinity of 1.012? I'm worried the good bacteria in the fluval will not manage the higher salinity. I'm I worry needlessly? I hope that makes sense. I can't take the fluval over yet, because my GSP is in that tank, and needs to have a filter running. Thanks much!!

To be honest, I don't know wether the bacteria will be ok going from 1.018 to 1.012. Never had anyone take them from Marine to Brackish.

Tank looks good though. =)

Reefing madness - thanks for all your help. Another forum (puffers) is telling me that Live rock won't live in 1.017, but I'm not raising the salinity anymore at this point than where it's at at 1.018. If the live rock dies, so be it, but I'm counting on you being correct Currently, parameters are reading some ammonia .025 and nitrates at 5ppm, but no nitrites!

I'm going to see what happens when I move the other filter over to higher salinity. I'll keep an eye on the water parameters, and should be okay, because it is just one small GSP in a 68 gallon.

Thanks again. I'll keep you posted :)

The Live Rock is not going to die at 1.017. The bacteria will grow on it no matter what salinity level you have it in. But if you raise or lower it to fast that specific bacteria that was growng may die off, but new bacteria will gorw in its place.

So, can you help me understand how SW cycles? If I'm now getting a reading of .50 for ammonia, and 10ppm for nitrates, but have 0 nitrites, will I expect to see some nitrites, or could the tank cycle without that happening?

I'm trying to figure out how long this will take, because I have someone who wants to take my smaller tank, when I upgrade my fish to this larger tank. It's tough being inpatient

Thanks
