low salinity

My usual routine is to run about 30-32 gallons of RODI for my water change, and I mix my salt overnight. I use Red Sea Coral Pro and have never had a problem. I realize instructions say not to mix more than 2 hours, but by aerating it overnight I’ve had better luck with a stable reading. I’ve...

Yesterday I upgraded my sump and added fresh water to it, tank was due for a water change but ran out of Red Sea coral salt. Anyway I turned the pumps back on and added a lot of beneficial bacteria to the tank (100ml). Today I torched are looking happy as ever so I checked the salinity and it’s...

Hey everyone. I'm curious to see what anyone has to say about the lowest they've seen their salinity in their tank with corals still thriving? I recently realized my tank was running at 1.020 for quite a long period of time. Verified by 2 separate digital Milwaukee checkers. I've since brought...

I’m brand new to saltwater so I decided to get a EVO 13.5 gal to start off. I bought water from my local aquarium store… I set everything up with the sand and rock I bought all the essential I thought I would need expect (protein skimmer) but it’s been 2 days and 1.023 PPT and i was told it...

I just noticed My salinity is around 1.018 and i don't own a RODI unit yet so I have no way of raising it since it's Christmas Eve and I have no idea if any stores will be open tomorrow, I have about 3 gallons of RO water in a jug so I might be able to mix salt water should I get my hands on...

Hello! I just had the surreal experience of winning a salt water tank last night. it is 30gal and has a variety of coral, live rock, a few types of snails, 2 Peppermint Shrimp and a young Clownfish. I was able to set it up last night with 90% of the original water and added 3gal of distilled...
