Thanks for your interesting comment! I have done water changes with tap water for years now, without conditioner etc. and never faced any problems, even bred several types of fish and shrimps. However, I live in Germany, and chlorine is only used in very rare occasions to purify the tap water. I also know my water pipes are new and not made out of copper to my knowledge, and I also tested it once, there was no trace of it. But of course, you should only use the tap water for the water change if it doesn’t harm the animals!!

What evidence do you have copper pipes release anything into water passing through? Your copper pipes must be different to everyone else’s.

From my knowledge, copper pipes can leak if you have certain water parameters that „attack“ the copper chemically. Normally, a protective layer builds up relatively fast and no copper gets into the water. But normally, in areas with those water parameters, copper is not used for pipes. But I don’t know much about it, only that copper in the tap water is usually not a problem for aquariums, and many people keep shrimps for example, so it would get noticed pretty fast 👍

Great Idea! 👍

Someone else also mentioned that the back pressure could be a problem. I haven’t noticed something like that yet, and my water should have quite some calcium in it… but I‘m not an expert on this matter (plumbing) at all 😂

They Just Make it so much easier! Greetings from the other Side of the ocean ✌️

Hey, that’s absolutely no problem, negative experiences are useful and part of the topic :) I am not a native speaker so I am not familiar with every single technical term you used, but I understand the problem. I honestly have never thought about this issue. I know that many people use a system like this for many years and never face problems like this, but of course every house and plumbing is very different… Personally, I always avoid having pressure on the system when it is completely closed. That’s why I explained all the steps that detailed, so there is never a moment where the water is on and all the „exits“ of the adapter are closed. And I never use the system with the full water pressure, maybe 30% tap flow at maximum. Did the plumber tell you whether this is a general problem or was this the cause in combination with another issue? Thanks for commenting your experience!

The plumber was unfamiliar with the Python device, but I did some searching and found that "modern" faucets are not designed to withstand back pressure . I guess they were not designed by aquarists!

Okay, I have not noticed something similar yet, and I hopefully won’t. But sad that you left the hobby because of this, why don’t you try out a nano tank where a 50% water change means 5-10 liters? There is something coming in that direction as well, maybe it’s an option for you… :)

Thats Great! It really depends on the tank, but from my experience, this doesn’t work well for Aquascapes when there is heavy fertilization, like in my case. But in many low tech setups, you don’t need water changes to achieve success :) Do you fertilize and have lots of fast growing plants? Or is it a „classical“ low tech setup?

Hi, I‘m sorry to hear that! I never had quality problems with this adapter so far, but maybe you had the older version. They changed some things some time ago… Now considering the vacuuming, I am absolutely with you. I haven’t even tried it yet because I know that it can’t work with such a small height difference and weak flow. I do this the Classic way with a bucket. That’s why I chose not to talk about the Aqua In-Out System and only about the adapter, because I only use it for water changes and everything else should better be done a different way. I hope you still had some amazing results with your tank, and the good think is that on smaller tanks, the water changes can be done the classical way quite easily :) Thanks for commenting!

@@passion4aqua Yes, maybe I had a bad luck and they probably improved it in the mean time. To be honest, yes, flow is weak but it works. And idea overall is great. No buckets, no splitting water... just hoses and this module. I think the point is: if your tank is closer to the sink you will get stronger flow. Maybe its about diameter of hoses as well... You should try it anyway :)

I might try it out someday! But the height difference is essential, you can see the difference of flow when you do a water change with a bucket and an equal diameter hose… for water changes, this tool is just great in my opinion :)

That’s why I made, I’ve heard this concerns a few times now.

Cheers from Germany! 👍

Thanks for commenting! Unfortunately, I fail to understand what exactly you are warning me about (not a native speaker)… can you write it again in different words so I can understand it? 😂

@@passion4aquaA little late, but I think he meant putting a stainer under the outlet so you don’t accidentally siphon a ton of gravel down the drain and block it.

Thanks for your help! That makes a lot of sense :)

Hello, thanks for commenting! 1. I dont know where you live, but I also have warm water during the winter period, that’s why I said that the temperature should be tested upfront, so warm and cold water can be mixed in the right ratio. I don’t put in cold water of course 😂 2. I also mentioned this under another comment, where I live, the water is pretty much safe to use straight from the tap, I have done this for years and even bred and raised juvenile fish and shrimp like this, so I would say there are no problems. In general, I know many people here (in Germany) that just use tap water for their aquariums, also in combination with big water changes (Aquascaping). Of course, if you live in a country with „bad“ tap water, you should treat the water accordingly before you put it in the tank. Or just do smaller water changes. About the 50% water changes, I understand your argument, but I would also argue that too small water changes result in a build up of certain parameters over time, especially when there is a strong fertilization like in my tanks. Of course, in a blackwater with lots of tannins and low ph or other setups with extreme water Parameters, big water changes might not be the solution. But I believe that more water changes are beneficial for the tank in general, and my tanks that were the most stable in the past were always the ones with more water changes.

Thats great! There are many ways to make Water changes easier… I found this one to be Really practical for „smaller“ tanks, but for people with many Tanks and/or big aquariums, a More advanced system is probably the way to go 👍

@@passion4aqua yeah might give this ago for the smaller tanks. Thanks for the video 😁

Happy you liked it :)

This one is from JBL: www.amazon.de/JBL-Wasserwechselset-Aquarien-Anschluss-Wasserhahn/dp/B08WJSW83X?th=1&psc=1 There are multiple adapters like this one, all of them work the same. Just pay attention that the one you choose is compatible with your sink, if you can’t screw it on the sink it won’t work! You can search „water change system aquarium“ or „water change adapter aquarium“ or something like that on Amazon 👍

It is from JBL: www.amazon.de/JBL-Wasserwechselset-Aquarien-Anschluss-Wasserhahn/dp/B08WJSW83X?th=1&psc=1 But really the only thing that matters is that it fits your sink, so make sure that it is compatible with yours, there are many products like this and they all work the Same. Although this one has the typical good JBL Quality :)

My tap water doesn’t contain any chlorine 👍 If yours has some in it, you should add some type of conditioner in the tank before you fill it up again.

@@passion4aquamaybe tell your followers that you have a well.. that way there are no embarrassing situations that you may inadvertently cause… take care 👍

You too! 👍

Hi, I didn’t put a link on purpose, because I don’t want people to just buy it because I showed it! The most important thing about a water change adapter is that it fits the sink. And JBL is a German brand (I live in Germany), so it is made for the typical sinks in mid Europe… I don’t think that it would fit the typical Asian And American sinks, which is why I wanted to show the concept, but not the product! The brand is not that important, but the connection to the sink is essential! If you are sure that it fits your sink, the one that I use is this one: www.amazon.de/JBL-Wasserwechselset-Aquarien-Anschluss-Wasserhahn/dp/B08WJSW83X?th=1&psc=1

@@passion4aqua ah ok. Understandable, thank you. I found one but it had mixed review so I might try a dyi

Interesting, good luck with the project! :)

That’s unfortunate, especially with 16 tanks 😂 but I have a project coming up where I can’t use my tap water as well, so I will definitely make a video about a more advanced version of the process for sure 👍

Very unfortunate, I didnt realize how much luck I have with my tap water until I made this video 😂 But I will do a project soon that I will not be able to use my tap water for… so there will be Video about using this water change system with altered tap water too! Stay tuned and thanks for commenting! 👍

Vielen Dank, freut mich, dass es dir gefällt! :)

No, I live in Germany, and the tap water is not treated with chlorine, only in very extreme situations (floods etc.). In general, tap water here is very good to use for aquariums (too hard sometimes, but no contamination with copper etc.). I actually never heard of water conditioner before I watched some US Videos 😂 But depending on where you live and what you have in your tank, you should treat the water in a tub and then pump it in the tank :)

You are soooo lucky. My tap water has chlorine, chloramines and nitrites.

Oh that’s unfortunate! Do you use a dechlorinator? Or do you make the water completely „from scratch“ with a reverse osmosis system?

@@Karbent you can put conditioner for the entire Tank first before refilling it. Remember to treat the entire tank not just the amount of water you replace.

Ah ok, interesting! So you should be able to use the water change system in combination with the water conditioner right?

They have multiple options to screw it on, so it should probably fit 👍 All the best for you and your tanks!

@@passion4aquaThanks!

Did it fit?

@@passion4aquait did! it's great

Happy to hear that 👍

No, I‘m from Germany :)

Can’t confirm that myself, but the video is about the system itself and not a specific product. But it’s great that you found a solution that works for you!

Why is that?

@@passion4aqua Ordinary tap water is fine for filling up the aquarium as long as you let it sit for several days before adding fish (the chlorine in the tap water will kill the fish). Also the temperature of the water you add may shock your fish.

I have no chlorine in the tap water, so I luckily don’t have that problem myself :) As mentioned, I always adjust the temperature before pumping the water in, it is just a matter of balancing hot and cold water. Maybe I should make a pinned comment about this matter, I have heard these concerns a few times now.

Hot water from the tap can contain contaminants. In England we have chlorine and Fluoride in our water so it has to be treated. Your video is very well put together and I am only pointing out what I have, 'not to discredit you in any way but to educate those who may not realise in many countries we have contaminates in our water.@@passion4aqua

No problem, I made a pinned comment about the issue. I was not aware that this was a common issue in so many comments… thanks for commenting! :)
