Seachem Prime Water Conditioner, 250 ml

I've been using Seachem Prime Water Conditioner for years. One of the things I appreciate most about Seachem Prime is that it's very concentrated. I only need to use a small amount of the conditioner to treat my entire tank, which means that a single bottle lasts for a long time. This is particularly important for me, as I have a large tank and was previously using a less concentrated water conditioner that required me to use more of the product. Another great thing about Seachem Prime is that it's very easy to use. I simply add the recommended amount of conditioner to my tank each time I do a water change, and it does the rest of the work. Seachem Prime also has the added benefit of not affecting the pH level of my tank. This is particularly important for me, as I have a delicate ecosystem in my tank that requires a consistent pH level. I've found that some other water conditioners can cause fluctuations in pH levels, which can be harmful to my fish and plants. With Seachem Prime, I don't have to worry about this issue. Overall, I would definitely recommend Seachem Prime Water Conditioner to any fish owner looking for an effective and concentrated water conditioner. It does a great job of detoxifying tap water and keeping my fish healthy, without affecting the pH level of my tank. Plus, the concentrated formula means that a single bottle will last for a long time, making it a great value for the price.

Read loads about prime so decided to give it a go. It's actually great, it's highly concentrated so only need a little. It has easy instructions and does exactly what it says. I wouldn't use anything else.

Works well. Always have in for my axolotls

Product as described, my 2 little water babies will be thankful after cycle crash as am i. Great price too many thanks

Requires very little of this solution to treat a vast quality of water. The one thing I hate is the paper seal under the cap wasn't firmly glued to the cap, and I've had to carefully put it back each time I've used it. Otherwise, I highly recommend it.

I discovered yesterday, much to my horror, that my nitrite levels had spiked to around 4 - 5ppm - this is a toxic level for fish, my nitrate levels were up at around 50 (again not good news). I was gutted as I love the fish. I think the fault was not cycling the tank properly before I put my fish in and a few days after I bought my fish I changed my old and very used filter sponge for a brand new one - convinced I was doing my little fishies a lot of good! Yesterday afternoon, upon reading the results of my water test, I immediately did a 50 per cent water change and ordered this Seachem Prime as it had many reviews saying it immediately got rid of nitrites, nitrates and ammonia etc This morning when I woke up I did another 25 per cent water change and an hour later tested my water - I had managed to get my nitrite levels down to roughly 2ppm. This is still no good, they MUST read 0 or your fish are in danger. The Seachem Prime arrived today (less than 24 hours after ordering) and I immediately put 3ml into my 60L tank, which is 3x the stated dose but I had a nitrite emergency and felt happy all would be well. I read my water levels an hour later and the nitrite readings are now roughly 0 - 0.5. It has clearly had an immediate effect on these levels and probably saved my little fish. I also have 3 minuscule little fry in the tank and I am hoping it has saved their little lives as well. The nitrate levels are now at around 20 ish which is perfectly safe for fish. I am planning to put around 1ml of Prime into my water every 24 hours now, and do a 25 per cent water change twice a week until I think my tank has cycled fully. I will then reduce the Prime to once every 48 hours and continue to test, then once every 3 to 4 days and test to ensure there are no spikes and that my tank is cycled! I am so grateful for this product, I did not sleep a wink last night desperate to sort this problem out! Just to note, Seachem Prime can be used as a water conditioner by itself and it makes tap water safe for fish. However because this product had not arrived when I did my water changes I used API Stress Coat Plus in my new water which also makes tap water safe for fish as it removes chlorines and chloramines etc The Prime can be used in conjunction with other products, it will not harm the fish. In future when I do water changes I will use Prime only as my water conditioner. I also use a Gravel Cleaner liquid which breaks down waste and slows the build up of green algea. I cannot recommend this product enough if you have a nitrite spike, it will save fishy lives! UPDATE: LESS THAN 5 DAYS AFTER STARTING WITH THIS PRODUCT NITRITE AND NITRATE LEVELS BOTH 0. This is a great product. I'll now only use it as a water conditioner with my weekly water change!

After 30 plus years with tropical fish tanks this product is the one that I always purchase. I assume it works as I never have any issues with replacing the water in my fish tanks with water from my taps. I go through a lot of this conditioner as I am a little OCD with the two tanks that I am down to and I never measure it precisely so I am probably adding more of the liquid than I need. A 500ml bottle still lasts me several months and I would just recommend that you get the largest bottle possible as it makes a difference to the end price.

worth the price and it lasts ages

Le produit a un réel impact sur les analyses d'eau, très efficace à petite dose. Seul aspect dérangeant: son odeur de soufre à l'ouverture de la bouteille. Mais une fois dans l'eau ça ne sent rien. J'ai reçu par contre une bouteille abimée, l'embouchure était tordue et une fois enlevé l'opercule, l'étanchéité était compromise, j'ai dû transvaser le produit dans une autre bouteille.

Produit toujours au top pour mon aquarium, jamais eu de soucis et flacon qui dure souvent plus que les autres car moins dilué avec de l'eau que certaines autres marques.

Very effective

The story starts with my old established tank being broken by relatives kid and it just broke glass on base and one side. i have large angels, peacock rainbows, corycats and bosemani ranibows. i decided to make a new tank instead of fixing the old one, due to the size issues i had to give it 3 days after siliconing it to let it dry out, by that time the bacteria in my filter might not have survived as there was no circulation in filter. i brought prime to cure my issue of new tank syndrome as it was going to be a fully stocked tank, thankfully i had my sponge filter working in bucket so it had the bacteria colony from my old tank. seachem prime did what it was suppose to do, it helped me set up a tank and i just lost 1 fish. Its costly but considering its a highly concentrated solution and you just need 7ml for 300L (my tank is actually 290L) it would last you a long time. if you use any chlorine remover, you can replace it with this. it also converts ammonia/nitrate. please do remember adding this is not the end all of your regular maintenance, you will still need to change the water depending on stocking level of your tank and tank size. i highly recommend this and in long run it turns out to be around same cost as any other item.
