so at the moment I don't have a ro unit, so at the advice of my LFS I used sea pora natural sea water, it came in 5g jugs. so I added the sand, live rock and the water on sunday. so I test the saltwater with my hydrometer and its reading 1.021..so my question is. was it bad to use that water? how would I go about raising the salinity? should I go back to mixing my salt? can I still do that? tank has no fiish or anything in it yet. thanks in advance everyone

you can add salt slowly and begin raising the salinity. You wanna be closer to 1.026

Also get rid of that junk Hydrometer and buy a refractometer. They give piss poor readings over time.

So should I buy salt and add it? I still have a jug of that sea water, but I don't think adding that would help right? I am in the process of getting one actually.

Went and got my water tested and tested the hydrometer to a refractomer and the hydrometer was reading accurate.

That's what I was gonna do. So I guess it's best to go back to mixing my water instead of this pre made stuff

It will be WAY more cost effective to purchase an RO/DI unit. More money upfront but a huge cost savings. I then stock up on my salt mix for the year at Big Als during their Boxing Day sales. Considering you ned to top off water constantly and bi-weekly water changes, the unit will pay for itself in no time.

I'm trying to convince the wife to get one lol. Does it matter that we don't have a water softener? I've checked a few places like water depot and they wanted 600. I know they are cheaper but where?

royal aquariums may still have them on sale if they havnt closed yet... you can pay any where from $100 for fish only tanks up to $300 or so if you are running an sps setup and anywhere in between plus bells and whistles.. imo something like a 4 stage 75gpd setup is good for the average reefer..

till then find a corner store with an r/o dispenser and buy salt... instant ocean is popular and easy to find..

Thanks dale, that is what I did with my last tank. i just picked up some ro water. For the ro unit does it matter if I don't have a water softener?
