Can i relax the water changes?

1201td

so i’ve been doing weekly water changes for a while, around 25% cuz my tank is cycled and i’ve been putting bottled BB into my tank (i just do water changes to keep my nitrates stable). anyways, i was just wondering if i can stretch it out to every 2 weeks since my tank is cycled. can i?

I wouldn't at that small of a percentage.

I’d actually increase your weekly change to 50%.

I can save you some money though. . . Stop using bottled bacteria. It’s unnecessary once your tank is cycled.

Sure. I personally don't see a problem doing monthly or even quarterly water changes, provided parameters are still in check.

I wouldn't advise that blindly without knowing the setup (plants, filtration etc.), especially to a beginner with a freshly cycled tank. If the tank was well established, lightly stocked and decently planted, maybe, but without any info? I don't know...

ok thanks

i forgot to mention i have 3 guppies and 4 neon tetras. would you still say it’s ok? or do you think i should keep up the weekly water changes.

it’s ok, i’m very paranoid so i’ll keep the bottled BB (i have gotten the advice to put it away if i’m not okay with spending money on something i probably don’t need) but thanks for the advice!

What size is the tank and what kind of filtration do you have?

I would bump it up to 50% a week myself too. Your cycle is too new right now for skipping water changes.

That bacteria really is not doing anything for you. You only need so much bacteria to eat the ammonia from your light stocking. Changing only water doesnt remove it.

I would use it if you stock more fish, do a filter clean or something like that sure. If you want to.

I think except in special setups waterchanges always have to be weekly. Just the stocking doesn't help. In a 30 liter no plants, hang on back filter, just cyled that stocking would warrant 50-75% a week. In a 100 liter, densely planted (and I mean all green jungle style), oversized canister filter and established for 2 years, every 3 weeks, maybe once a month, is absolutely fine.

What size is the tank?
Yes. Best with a picture of the tank.

Nitrates are a good way of determining how often/much you change your water. It's not the only consideration though. Our water contains minerals and buffers in it that keep our ph steady and fish and plants healthy. Sadly we don't have an easy way to measure this or know how much is enough. It's probably ok to cut back a bit on the water changes just keep an eye on ph/nitrate and fish health and maybe every few months do a big water change. It's not an exact science.

The problem with fewer water changes is that you find out you're not changing enough water when your animals get sick.

When you do weekly water changes it keeps your tap and tank water closer to each other. There isnt as much of a shock from bigger parameter swings.
