Water change

[tybooyahh]

Hi,
This is my first post on this forum so I hope Im making it in the right category, if not, sorry in advance.

Basically I have 200l tank with tripical fish and Im making partial water changes every 7-10 days, usually 35-50l. Before when I had 60l tank every time I was buying 5l btls of water, adding tap safe and changing the water. With new tank Im changing water with tap water and tap safe.

Sometimes Im busy and dont realy have time to make a change on the usual day so I do it day or two after. What I was wondering is, if I can prepare tap water with tap safe on one day but lets say I will change the water after 2 days. Is that prepared 2 days before tap water with tap safe will still be good to use ?

You can prepare the water on the day you do the water change. Most of us add the dechlorinator to a bucket, run water in and add it to the tank. One or two members allow the water to stand for 30 minutes before adding it to the tank. Those members who refill with a hose usually add the full amount of dechlorinator to the tank then run the water in. I would just empty the tank, then add the tap safe to the new water just before you put it in the tank.

The recommended water change regime is at least 50% once a week so with your 200 litre tank you need to change at least 100 litre every time.

Thank you for your reply. I know that tap safe products work basically after few min after adding them into tap water. I was about to change the water 2 days ago after work so I prepared water before work but I finished late and I did not managed to do it. Now I want to change the water today but Im just wondering if it is safe to use the same water from 2 days ago or should I just prepare the new one ?

Im using Fluval Aquaplus Aquarium Water Conditioner

The water is fine to use as long as the temperature is close to that in the tank. I just test temperature with my hand, others use a thermometer to get it within a degree or two.

In answer to the question, yes its fine. The conditioner removes the chlorine and once its gone its gone - so there is no problem in letting the water stand for a few days after adding it.
Just FWIW I would change around 100 litres per week. I have a 200l tank. With the substrate and air gap at the top it actually holds around 160 litres and I usually change 120 litres every week. Its the tank you can see in my signature.

I will start doing bigger changes than. The reason why I wasnt doing more than 50l changes it is because my water in the tank is fine. Im testing it every 2-3 daya

And when it comes to temperature , I have a problem now as Im trying to fight. Basically my entire flat is hot and sometimes the temp in the tank is as high as 30C but Im bringing it down with frozen btl of water and ice packs

I do weekly 50% water changes. The water may test fine but there are substances that build up that we can't test. Changing water reduces these chemicals and organisms. fresh clean water is the best medicine for th he fish , preventative AND reactive.
The fish will cope with the temperature fluctuation, it happens in nature and in London it won't be that high consistently. I'm in the midlands, I've never needed to cool a tank. You may find its sufficient to remove the lid in the warmest part of the day.

Cool coop thank you all for the advise. Once all of us are here I might need help in one topic, well in two but they are connected. Basically I have a very mean yoyo loach. I mean generaly he coops great, what Im surprised with old buddies like cory(I know, bad comoination but they are totaly fine) or neons tetra. The only problem is with new added fish, he goes crazzzzy, specially the last time when I added small angelfish and 5 glass catfish. He went mad on them so I tried to rearange the whole tank 3 times already but nothing changed and it made me to put him in breeding box. I have him for 2 days there already but I want to know if there is anything also that I can do to make him more, hmm friendly before I will give it away to fish store ? Also my glass catfish seems to be very stressed or shy. They stay all of them in one place all the time, they do not eat when it is food time. They only come out after the lights go off and thats when I try to feed them and the eat a little bit but during the day they wont come out and they wont eat woth the rest of the fish.
