Seachem’s Clarity water clarifier for marine and freshwater is the ultimate solution to remove cloudiness from your tank or aquarium.
For over three decades, Seachem has been a company rooted in sound science. Our experience in the hobby and an educated staff of chemists and biologists are part of the package when you purchase Seachem products. Seachem remains as one of the few surviving independent and privately owned pet care companies. Seachem is owned and operated by hobbyists. All of our employees are hobbyists who maintain aquariums at home and at the office. Seachem itself was started because one such passionate hobbyist - Dr. Leo G. Morin (Founder) - recognized that the available solutions to aquarists problem wanting. This resulted in Seachem’s very first product: Cupraplex (today known as Cupramine). Over thirty years later Seachem is still approaching old problems in a new way.
Seachem’s philosophy is that the knowledgeable hobbyist makes the best customer. This is reflected in solid and reliable customer education and support as well as products proven in science and performance. While Seachem has grown rapidly into a national and international firm, it retains the culture of a small company and is readily available to its customers.

Does a great job at collecting the little particles to be sucked up by the filter, keeps water crystal, good for the price

This is an excellent product and works exactly as described. I had some residual cloudiness in my Mbuna tank and from some aquarium sand. After two uses this product completely cleared up the water. And it is crystal clear. You need fine filter floss to use this product correctly. After using it you will see a large amount of orange debris in your filter floss. Repeat as needed, but only takes one or two uses. Highly recommend this product.As the label states you will see an initial haze, but it clears up after two hours and stays clear.

This product is great. My filtration system does its job very well but there are times when my water is a little cloudy. I’m a fanatic about clear water. This does the trick. Use as directed and know your water will be cloudier for a while that’s how you know it’s working. It attaches to the particulates in the water column so the filter takes them out. I have purchased this several times and will purchase it again.

Ho testato il Seachem Clarity e devo dire che è un prodotto straordinario per mantenere l'acqua del mio acquario cristallina. Questo chiarificatore è efficace sia per acquari d'acqua dolce che marina, e la confezione da 100 ml è molto pratica.Dopo averlo utilizzato, ho notato che l'acqua diventa limpida in poche ore. Clarity agisce legando particelle in sospensione, facilitando la loro rimozione tramite il filtro. È semplice da usare: basta aggiungere la giusta dose e lasciare che il filtro faccia il resto.Un altro aspetto positivo è che non sembra influire negativamente sui pesci o sulle piante, il che è fondamentale per chi ha un ecosistema acquatico. Consiglio vivamente Seachem Clarity a chiunque desideri migliorare la qualità dell'acqua del proprio acquario. Un ottimo prodotto da avere sempre a disposizione!

I've used several other brands of aquarium "de-clouder" and this is BY FAR my preference.This brand is the best deal because YOU USE MUCH LESS product per use. LESS THAN A CAP-FULL for 10gallon tank. The product works very well. Its not instant (mine was overnight), but good quality takes good time.Definitely try it out.

Clears up cloudy water in a few hours IF you have filter floss or sponge filters. It binds to particles to make them large enough to catch and remove with fine filters. It's not a magic potion that turns water clear for no reason. Not good for tannins from wood or milky water from bacterial bloom. But if you bought this not knowing what you're clearing up you shouldn't be in this hobby to begin with.

I don't own fish; I actually bought this to see if I could use it to get all the air bubbles out of a desktop toy: LED "jellyfish" tank. The additive forces water impurities out of solution near-instantly; after a few minutes of letting the pumps recirculate the water, I switched it off, and waited. In about two hours, all the previously dissolved solids had formed a thin layer on the bottom, and all but a handful of tiny bubbles had collapsed.If the tank had filters, I suspect the water would be totally clear, now. For my purposes, it actually works better than expected; when the pumps are running (on and off) for about two minutes, the solids stirred back up from the bottom turn the water very slightly murky, which gives the LEDs a cool "spotlight" effect; like shining a light through seawater. The bubbles from the tap water remain banished, and the latex "jellyfish" no longer bob around at the top.If only the jellyfish tank had shipped with a small amount of this. And filtration.
