Fluval A1447 Activated Carbon 900 g

First time ordering this product, good from the start. Packaged well and seeing an improvement in my tank water quality after just a few days, proving to be an effective product. It’s a good sized amount in the tub and easy to set up with the mesh bag provided.

As there is a bag attached it is easy to fill it as much or as little as you need to. Although it says 'bags', there is only one bag attached but it is reusable. I find this product does help to keep the water clear, alongside other items placed in the filtration system. I am happy to recommend it.

Product is ok it is just that the lid had come off so contents had emptied in box.

This carbon is high quality and keeps your aquarium clear and clean smelling. I use it in a freshwater aquarium and it’s down to personal choice really. It won’t solve problems such as algae growth but definitely gives the water a nice polish. As every other review says; it only comes with one bag but if you're using the fluval 30X or 40X filters you can just put the bag over the partition and spread it over both if you plan on using a lot. Keep in mind that you do not need as much as you think; I put in almost a half and it barely fit into the baskets of my 306 filter and I had already rinsed it thoroughly so couldn't take any out. It comes with about 5 small zip ties to close the bag but if you expect to be using less than a fifth of it each time you can easily tie the large bag it comes with in a knot. It works out much cheaper than the individual bags so I cannot complain!! If you want a media bag with a zip and a mesh that’s fine enough to keep this stuff in I recommend Seachem’s small zip bag - it’ll take some of the faff out of replacing the carbon.

Good, better than using carbon filters

First of all if you have an algae bloom deal with it first, I personally use Algumin, follow the instructions and in a few weeks it’s all pretty much dead. But in order to control the growth of algae I now use Clearmax, once any bloom has been dealt with :D Ok so this helps to get rid of algae’s food source ‘phosphates, nitrate and nitrites’ by trapping it in this clearmax resin. It does this very well indeed. The box has 3 felt bags containing 100g each of the clearmax resin, your supposed to use 1 bag at a time and replace after 30 days, each bag is suitable to treat a tank up to 100 litres. But my tanks only 20 litres!? So seen as I haven’t got money to burn I go to poundworld and buy a pack of stockings, cut open one of these clearmax felt bags and pour a 1/3 in then tie off the stocking and cut it and so on, so I am left with eventually 3 x 33g (stocking) bags of clearmax out of just 1 of the felt bags. So now 1 box gives me 9 months of use. I’ve been using it for 4 months now and I have next to no algae growth at all! Well worth the money especially if you do the mod like me for a smaller tank :D

Faisant confiance aux commentaires positifs, j'utilise ce produit depuis le mois de février 2025. Mon eaux trouble et devenue limpide... (quelques jours suffisent). J'utilise deux sachets de 100 gr pour mon aquarium de 250 litres que je change tous les mois dans ma pompe externe. C'est parfait. Je vous recommande ce produit sans hésiter.

Nutze die Aktivkohle für die Bong - zum reinigen des Rauchs und fürs Katzenklo. Funktioniert beides super, dank der genialen Körnung. Kann ich für diese Zwecke auch empfehlen.

Use it in my pool sand filter. Works great.

All okay. Works as described. My fish are happy.

How fantastic this product is! Huge improvement to the water quality. Does not harm plants. Fish are exxtremely happy, energetic again.
