Do you have to do weekly 10% changes if the water perams are good?
Yes, if you want them to stay that way. If fact, some people change 20% every week, but it depends on the tank.
Really you need to monitor the Nitrate levels in the tank, and then adjust the amount of water that is changed out to maintain a healthy tank. This may be as much as 50 / 60 % of water if your tank is heavily stocked.
It is a good idea to change at least 10% of the water weekly just to keep the water params in good check and add and replenish vitamins. I do a 30% water change weekly to ensure my fish are in healthy water. It is nescessary to do water changes to minimise the amount of ammonia in the water caused by fish waste. Ammonia is part of the nitrogen cycle and a cycled aquarium is needed for keeping fish sucsessfully.
I do 30-40% weekly to all my tanks, understocked or not. Disciplined myself before starting out.
I do at least 50% weekly, water changes are not just about keeping nitrates down they also replenish minerals used up by the fish & plants. Thread of interest https://www.fishlore.com/fishforum/...p-up-water-changes-your-fish.html#post1290981
I do 50% weekly on all of mine to ensure their waters minerals are replenished
I guess I have to step up my game then, an additional 10% would not hurt.
I always do a minimum of 25% weekly. I usually aim more around 40-50% weekly. Like stated above its about replenishing minerals in the water as well as keeping the parameters in check
Ok, i usually do a 10% on my 55g & 10g, and a 20% on my 210, so i should in reality be doing a bigger water change?
I would at least do 25% weekly and a 40-50% pwc once a month. Ideally, I would suggest a 40-50% weekly. Do you have a python or aqueon water changer? It will save your life!
A python/aqueon water changer is indeed a life saver. I do a 50-60% change every other week. Sometimes I do every week. It's always good practice to do it weekly.
No, this is what i have https://www.amazon.com/Aqueon-Mediu...&sr=1-1-fkmr0&keywords=Aqueon+aquarium+syphon
How high are your nitrates?
If you have any tanks near a sink (mind you they have 25ft, 50ft, 100ft tubes plus extra extensions you can add) you might want to invest in one! I use it on my 29g and it makes large water changes so easy and painless. I still have to use my gravel vacuum for my 10QT and 20g because the cover on the faucet in my bathroom wont come off. But even having 1 tank with the water changer was well worth it
For all tanks they are about 5
But how would i treat the water before putting it into the tank?
You put enough prime in to treat the entire tank volume before you run the new water in. Then let it flow in.
How it works: Take out the water while vacuuming substrate Empty the hose Get the temp just right Add prime for the entire volume of the tank Switch the function from suck to pour Add the water back to the tank Turn off Empty the hose Done!
I have 90 gallon tank with sump and three large blood Red Parrots. My fish love 10% per week or 25% every two weeks also works well. I what is easiest with my schedule. They because of the size can go 2 1/2 weeks then I do larger change.
