Marine salt for R/O and tap water

Thanks to its exceptional consistency and uniform grain size, sera marin salt dissolves swiftly and leaves no residues, resulting in crystal clear marine water. It helps to establish natural GH and KH levels, while being rich in calcium and magnesium in biologically suitable proportions. The pH value is kept stable and accurate, thanks to the natural buffering system found in sera marin salt.

Through a unique process, sera marin salt retains trace elements in a manner that keeps them consistently dissolved and available for extended periods. This salt does not include any substances that could artificially boost protein skimmer performance. Moreover, it is free from nitrates, silicates, and phosphates.

Sera (sea salt without nitrates, phosphates, and silicates) is rich in calcium and all essential trace elements required for successfully cultivating ornamental algae and lower resins in seawater. It contains a blend of special substances that aid in the removal of harmful elements such as heavy metals and copper. The salt dissolves rapidly and without leaving deposits. With its natural buffering capability, it ensures an optimal and stable pH level.

Instructions for use: Dissolve Sera marin salt (approximately 33 g per liter of water) to achieve a water density of 1.022 to 1.024 g/ml in a container using treated water (osmosis) or chlorine-free tap water. Aerate for 24 hours or thoroughly mix with a submersible pump to introduce oxygen and carbon dioxide.

Warning: Avoid dissolving sea salt directly in an active aquarium! We suggest replacing 5-10% of the aquarium water monthly and treating it with sera aquatan and sera bio reef clear to enhance water quality. When setting up a new aquarium, treat the water with Sera aquatan and Sera bio reef clear, and allow the aquarium, along with the connected equipment (pumps, heaters, filter...), to run for at least 14 days to ensure biological stabilization before adding any fish.

Great socks
Size: Medium, Color: Pink - 647
Well-made and comfortable to wear. Great for golf and other outdoor activities. Like them because they do not show above shoes.

These ACTUALLY stay put all day long - I was skeptical, but am so glad I took a chance on these
Size: Medium, Color: (014) Halo Gray / Halo Gray / Castlerock
I was so skeptical about whether these would stay on my feet all day without sliding down into my shoe - I’ve tried so many socks in the past with the silicone strip on the heel which failed. I’ve owned these for a couple months now and they have never slipped down - they stay put all day! I love the variety of colors to choose from, and the value per pack is great since six pairs come per pack (I thought it was only three when I first purchased and was pleasantly surprised by the additional pairs). They also have perfect thickness - not too warm to wear during the summer months with sneakers; I live in a tropical climate, though, so I’m not sure how they will do in cooler climates. I’ve washed each pair once or twice and the color and quality of the silicone has stayed so far (knock on wood). Overall: high recommend based on my experience so far!

No show but stays on
Size: Medium, Color: (014) Halo Gray / Halo Gray / Castlerock
I wear these socks daily. They truly don’t show with my workout shoes or with hey dudes. But the best thing about them is that they actually stay on your foot. I work out hard and I don’t ever have to pull them up. I do wish they were just a little bit thicker than they are, but they are definitely a product I will buy again.
