**Question of the week** | When’s the last time you did a water change?

[StevenF]

typically once week 50% but I-know I can go two weeks without a water change. During the water chanage I also add fertilizer. So when I am taking some time off from work I often just top it off with RO water and then add fertilizer. And then when I get home I do a water change.

A bichir in 55 gal Seems small to me for a fish growing up to 40 cm !
Doesn't it eat his tankmates ?

Don’t worry bud. He is 9 inches. Doesn’t care about tankmates. Giving him away. Delhezi Bichirs only grow 14 inches tops.

I change water when I can be bothered. I test once every two weeks... If I see any real nitrates I will go ahead and change 30% or so. This applies to both my tanks. I have a 10 gallon moderately planted with guppies and a 55 gallon non planted with a lone Blood Parrot. The tanks don't build nitrates fast at all.

Nice !
Many caresheets say up to 40 cm, eat whatever it can swallow, needs 1000 liters for 1 specimen....
I understand why you like it, there's a lil somethin extra with Bichir

How much ?

75%-90% on all the tanks except my QT tank.

Dont trust google. They say "Bichir". There are tons of apecies of bichirs. CB Albino Senegal being the shortest (6-8 inches), and Polypterus Endlicheri 'Congicus' being the largest at 36 inches

Let’s be honest with this one!

1. When’s the last you did a water change on your tanks?
2. Do you usually do water changes on weekends? Days off?

Please vote in the poll!

I do a 50% change every Monday on a well-established tank.

I think we need to address the people who said they never changed water

 

[Thomas Haslam]

I change my water 50% once a month during the week

 

[realgwyneth]

33 percent, every other week, usually on the weekend, for a pretty heavily planted 65g that is understocked. Sometimes bigger if testing suggests nitrates are creeping up.

That’s a very precise percentage!

 

[FishNturt808]

I water change every week-10 days. Usually around 30-40%.
but for the poll, I honestly answered last month (which was about 2.5 weeks ago) because I had to go out of town for 3 weeks for work, and didn’t want to leave the girlfriend with that responsibility. So I did about a 60% water change knowing it was gonna go awhile without it.

 

[ClownLurch]

Two tanks, 50% every weekend. Though Twas Monday morning this week.

I am glad to see I am not the only person who uses the word "Twas" whenever I say it people give me a weird look lol
