Seachem Prime Dechlorinator 250/500ml

Seachem Prime is the complete and concentrated conditioner for both fresh and saltwater aquariums. Prime removes chlorine and chloramine while also detoxifying ammonia by converting it into a safe, non-toxic form that is readily removed by the tank’s biofilter. Seachem Prime may be used during tank cycling to alleviate ammonia/nitrite toxicity. It will also detoxify any heavy metals found in the tap water at typical concentration levels. Prime is non-acidic and will not impact pH. Use at start-up and whenever adding or replacing water.

When transporting or quarantining fish, use Seachem StressGuard. When adding new fish, use Stability. Both are ideal for use with Prime.

Nearly all companies manufacture a product that removes chlorine. None of those, however, can compare in quality, concentration, or effectiveness to Seachem’s flagship product: Prime. A single 100ml bottle will treat 4000 litres of tap water. Prime will remove both chlorine and chloramines from tap water.

Prime also contains a binder which renders ammonia, nitrite, and nitrate non-toxic. It is very important to understand how those two functions work together. All dechlorinators operate through a chemical process known as reduction. In this process, toxic dissolved chlorine gas (Cl2) is converted into non-toxic chloride ions (Cl-). The reduction process also breaks the bonds between chlorine and nitrogen atoms in the chloramine molecule (NH2Cl), freeing the chlorine atoms and replacing them with hydrogen (H) to create ammonia (NH3).

Typically, dechlorinators stop there, leaving an aquarium full of toxic ammonia! Seachem takes the necessary next step by including an ammonia binder to detoxify the ammonia produced in the reduction process.

Be very careful when purchasing water conditioners. If your tap water contains chloramines, a standard sodium thiosulfate dechlorinator is not enough. Prime promotes the natural production and restoration of the slime coat rather than relying on artificial or non-native slime compounds. A further bonus for the reef hobbyist - Prime will not over-activate protein skimmers.

  • Complete and concentrated conditioner for fresh and saltwater
  • Removes chlorine, chloramine
  • Detoxifies ammonia, nitrite, and nitrate
  • 5x more concentrated than competing products
  • Available sizes; 250ml & 500ml

    Directions...
    Use 1 capful (5ml) for each 200L of new water. For smaller volumes, please note each cap thread is approximately 1ml. May be added to aquarium directly, but better if added to new water first. If adding directly to aquarium, base dose on aquarium volume. Sulfur odor is normal. For exceptionally high chloramine concentrations, a double dose may be used safely. To detoxify nitrite in an emergency, up to 5 times normal dose may be used. If temperature is > 30 °C (86°F) and chlorine or ammonia levels are low, use a half dose.

Great shelves
Size: 24 Inch, Color: White
Easy to assemble and comes with everything you need for drywall or wood. Nice color and texture and comes with stickers to hide the holes underneath. I bought two sets of three. These are very long, so I recommend just using two at a time.

JAXPETY Room Divider Panel 6Ft Privacy Screen Wall Divider 88" W x 73" H - 3 Panel Black
Color: Black, Size: 3-Panel, Color: Black, Size: 3-Panel
I was looking for a screen to use while making video calls. I am on a budget, wanted something easy to put together, and would hide my apt in the background. Being on a budget, I thought my purchase qualified for the coupon. I was mistaken but contacted the seller. I received a quick response explaining how the coupon was applied. I was happy with the quick response and explanation which I verified when I went back to the page. The once all put together the screens are light weight and fairly easy to move. they do not seem to be made for easy daily breakdown. However, if you should need to take them apart to move or something, easy to break down. Depending on lighting will depend on if you find them transparent. I don't mind possible vague outlines; I was looking so no real details of my belongings in the background could be seen (shelves; figurines; etc.) My apt living room has no overhead light source, so floor lamps give light. In the 3 photos of 2 of the screens put together; the first is with a lamp in front and back of the screen as well as a tv on. The next has the tv off lamps still on and the screen reflecting the pc monitors. The third is with both lamps and the tv off, monitors on but not as reflective. In the box, you have all the parts you need as well as a small tool and an instruction manual. Item 'bags' are number [though they may come off in the box] to assist with assembly. Now assembly can be easy or hard depending on your abilities and the area you are working in. I have bad knees, so kneeling was not an option for me. My first attempt to put this together, I put the 'feet bases' on while still connecting the top bar. It made it twice as hard, and I stretched the fabric more than was necessary causing wholes around some of the stitching and stretching them a little. As well as causing some stitching to come undone on one of the pictured areas. Once I took off the 'feet bases', I had an easier time to screwing in the top bars. You will still need some hand strength, which I don't have much of, but it is possible. I use the grip things to open pickles jars. Once the screens were assembled, I followed the instructions of tying an outer screen to the inner screen and using the Velcro 'privacy flaps' to complete the connection. I have what I think is low shag carpeting which they were able to stand stably on once I wiggled them into standing straight up and in place. Given these post pandemic times, I am overall happy with both the divider and the price. The 2 things I do not like about the divider is the difficulty putting in the top bar [after connecting the top and sides] and storability when not in use issue I am having. Others with larger space will likely not have the last issue.

100% worth it - I recommend to EVERYONE
I've seen coworkers and instructors using folding screens behind them for video calls since the pandemic started, and I finally gave in and purchased this one. I freaking LOVE it. I love that I can be on a video call and not have to worry about the angle of my laptop or having people 'in' my home while I'm at work. It's so nice. I may eventually buy and deconstruct a wall hanging to create some colorful fabric panels instead of the brown, but (and I say this as NOT a brown fabric-lover) the brown looks pretty nice. It's a very dark brown, and it serves as completely neutral while still feeling a bit warm. - No need for tools to assemble, even though it says screwdriver. - One thing: I thought it would fold up flat, and it does NOT fold up flat. Important to know. I just keep it folded up into a 16.5" (grabbed a tape measure to check) square column by my desk and unfold whenever I have video conferences. If you can't tell, I really like having this thing around. 100% recommend and would buy again.

it's a utility screen
Color: Black, Size: 3-Panel
It's a basic, utilitarian screen. It's what I expected it to be. Assembly isn't hard, but it does require two people when stretching the fabric between the poles. I got it to use in a closet to separate the water heater from the washer/dryer, so it'll be perfect for that. Pros: it's opaque and tall (my 6'4" husband can't see over it unless he is standing against it) and I like the ability for the three pieces to stand separately of each other. Cons: it's flimsy. It wobbles and will tip over easily.

Great for the price
The item is great bit I wish it were a bit more sturdy and it folded flat. It folds into a square so it does take up some room when it's not in use.
