SeachemPrime Fresh and Saltwater Conditioner - Chemical Remover and Detoxifier 20L / 5.3 gal

I got the smallest size and it will last me a long time. It doesn’t smell strong and it works well. I’ve used this brand a while ago and had to try it again.

I've been using Prime for quite a while now and it seems to be working out for me. When I first started out with my tanks I was using "Jungle" water conditioner and it seemed to do it's job but I wanted something more "top of the line" if you will. I didn't make the switch because I thought the "Jungle" product was inferior but I just wanted the "best" for my fish. I started researching about the best water conditioner and everyone kept raving about "Prime" they would talk about how affordable it was and the benefits that came from using this product. It seemed like the best choice for me so I made the switch I did notice that the stuff is very strong and concentrated so it doesn't take much to treat your water. As far as dosing Prime you just need to follow the instructions on the back of the bottle. I'm usually careful when I dose with Prime because of it's potency so when I prepare my water in a 5 gallon bucket I usually dose 2 drops per gallon. The reason I do it this way is because I don't want to overdose on Prime I rather be safe than sorry. With that said when I first started dosing with Prime I would dose it straight into the bucket of water. Then I would siphon the water into my tank without letting the water age. I started noticing that every time after I did a water change my fish would start gulping for air at the surface. I started reading certain threads and some people stated that in some cases too much Prime can cause oxygen depletion. Seachem has stated that you can overdose Prime about 5x the recommended dosage and it still would be safe for fish. I personally wouldn't take the risk especially if you don't have proper aeration in your tank. I know most people will say that it doesn't matter if you let your water age or if you wait for the water conditioner to take effect (since it works instantly) and they might be right but in my situation it seems to make a difference. I let my water age for about 24 hours and I sometimes even dose the water before letting it age. I also give the water a little stir just to make sure everything is mixed up well I'm not sure if it helps but I do it regardless. I've noticed that after doing all of the above my fish don't gasp for air anymore and they don't seem to be bothered at all by weekly water changes. The only downside to my method would be that the agents that lock down ammonia, nitrites and nitrates to something less toxic wouldn't really be taking effect. These locking agents stop working after 24 hours or 48 hours depending on how much you dose. I'm not too worried about it though because I keep my tanks fairly clean and I methodically keep up with my water changes. Be warned that Prime does not get rid of ammonia, nitrites or nitrates for good it just converts it to something less toxic which then allows your biological filtration to clean it up for a short period of time. Like I stated before Prime only takes effect for a brief moment and once it stops working the toxins that were locked down are released back into your water. That's where regular water changes come into play having clean water and using Prime in conjunction will definitely work to your advantage. I would say that in laymen terms Prime is a good water dechlorinator that happens to come with a few extra's. Would I say it's worth making the switch? I wouldn't really be able to answer that question because there are a lot of great products out in the market that work similar if not the same as Prime. I would however say that from a personal stand point Prime is a great product and it works very well and if used correctly it can be very effective and affordable at the same time.

Seachem Prime is perfect to use in a start up aquarium to remove chlorine and condition water. This product also can be used to detoxify ammonia. It is great to use with Seachem Stability, and Seachem Pristine. These products keep my water crystal clear and help maintain the health of my fish. The directions are very clear, and the caps can be used to measure appropriate amount of the product.Just follow the instructions on the bottle. Seachem also has a custom service number you can call for any questions. I would highly recommend Seachem products.

I wasted so much literal time and money on other products. I have 7 large aquariums and some plant tanks. The efficacy and length of time Prime lasts is the best and I'm never using anything else. The fish seem happier, plants grow healthier. I use it in my stillwater, worm breeding and Walstad projects as well. Arrived with no leaks.

My aquarium's nitrate levels were high and despite water changes, I wasn't able to lower it. I tried this product and it works as instructed. I fish look much happier and healthier as well. A small bottle will go a long way too.

love this and feel safe using this for when i do water changes, I have an axolotl so im always doing water changes anyway. Minus the sulfur smell this is my go to. Great brand!

TLDR: Prime is not a miracle product that can prevent "new tank syndrome". It works on chloramines, but not on ammonia, which is equally toxic to fish and invertebrates. If you have ammonia in your tap water, you will need to use something else when cycling your tank with livestock in it.Long version:If you have chloramines in your tap water, you need to either buy or generate RO (reverse osmosis) water, or use a conditioner like Prime to prevent the chloramines, which are highly toxic to fish and invertebrates, from killing your livestock. To that end, Prime works well, even for San Diego tap water, which is notorious for having high levels of chloramines.However, Prime also claims to "detoxify" ammonia, presumably ionizing it and changing it from NH3 to NH4 (ammonium). If you perform even a cursory search online, you will find numerous forum postings about the effectiveness (or lack thereof) of Prime. Many hobbyists and even some chemists have tested this claim and found no evidence that the proportion of NH3 to NH4 is any lower after treating with Prime.This lack of evidence for the "detoxifying" effects of Prime on ammonia is important because it means that Prime cannot save your livestock from "new tank syndrome" as claimed. New tank syndrome is the spike in ammonia that occurs when livestock are first added to a tank before the biological filter (i.e. the colonies of beneficial bacteria that convert ammonia into nitrite and then into nitrate) are established.If you are cycling a tank with livestock, you will need to closely monitor and manage the ammonia levels, and cannot depend on Prime to save your livestock. Instead, if you must cycle with livestock, you will need a product like Stability to temporarily establish placeholder colonies to break down as much of the ammonia as possible. You will also need to perform frequent water changes to get the ammonia out of the tank.As some municipal water suppliers add chloramines AND ammonia to their water, this presents a problem for water changes. If you have ammonia in your tap water and you add that water to your tank, you are adding ammonia, some of which will be the more toxic NH3 form. Without an established biological filter, this ammonia will poison your livestock. Therefore, if you have ammonia in your tap water, you need to use RO or spring water instead, at least until your biological filter is established and able to quickly process the amount of ammonia present in your water changes.

This product is great. I was having an issue with ammonia and nitrite. I did 5X the dosage as the directions suggested and immediate relief. This is essential for anyone with an aquarium.

Um dos melhores do mercado brasileiro

Can never use too much of this stuff and I live in the city where there’s lots of chlorine in the water. I add a splash to each jug I’m adding to my tank daily due to evaporation and I’ve had zero issues (salt water tank)

Mt bom a água ficou show recomendo

un excelente producto

Always need it
