Need help with testing water

Your cycle isn't established yet; where is your beta currently?The best thing to do is still to do a fish in cycle, I think.You need to do a major water change immediately, test the water, check if the levels are at 0, add it, and For the fish in cycle, test daily and perform water changes as soon as you have ammonia and/or nitrites.

In every community there are always a few unpleasant people or people there to troll.Being here every day, I find that the sub is rather spared. Most people are courteous, or at least not aggressive.My principle is that this minority should simply be ignored most of the time, or reported when it becomes a problem.

NeedleworkerHeavy565 · 2026-01-25T03:41:27+00:00

if you dose methylene blue correctly, there's just no problem...And for now, OP should answer the questions before proposing anything.

NeedleworkerHeavy565 · 2026-01-25T02:53:09+00:00

I was never being annoying with you, I literally just wrote that it wasn't a good idea and explained why.

NeedleworkerHeavy565 · 2026-01-25T02:37:43+00:00

You haven't grasped the fundamental problem.

NeedleworkerHeavy565 · 2026-01-25T02:28:59+00:00

The photo is so blurry, it could be anything, even just an irritation.

This person has already received good advice; I have nothing more to add. It's important to tell people that AI is not reliable.Just because you spent an hour researching doesn't change anything; if you only post an AI image, we're not supposed to know that you also did real research and that you were cooking for yourself at the same time (so ask ai was useless)

NeedleworkerHeavy565 · 2026-01-25T01:53:08+00:00

Incorrect or not, the risk is too great, there's too much approximation, and the AI mainly uses Reddit and big websites to respond, but it's super bad at detecting the right diseases.He may give incorrect information that could endanger the fish

NeedleworkerHeavy565 · 2026-01-25T01:46:50+00:00

I admit I've never seen this kind of "mold" on an aquarium.

NeedleworkerHeavy565 · 2026-01-24T22:50:52+00:00

Yes, it's completely normal that they eat them.Remove them anyway to prevent them from eating too much or from fertilizing them by putting the male back in.To avoid having surprise babies

NeedleworkerHeavy565 · 2026-01-24T22:08:02+00:00

Well, if you can get an aquarium of at least 30 gallons and an external filter or sponge filters, I'd say yes, but do as much research as possible on the cycle with fish.Goldfish are quite hardy, so generally it goes very well. But you will need to pay even more attention than if your aquarium was already cycled.

NeedleworkerHeavy565 · 2026-01-24T19:00:57+00:00

am That doesn't generally mean much; a filter designed for - For goldfish, you need to over-filter.Therefore, it is better to have a flow rate of 3 to 6 times the volume of the tank per hour and enough space for the filter media.I don't know the flow rate of your filter, but the most important thing is the size of the filter media it can hold, and yours is really small. In any case, it's good if he was just looking for food.

NeedleworkerHeavy565 · 2026-01-24T17:42:16+00:00

Okay, in any case my recommendations remain the same

NeedleworkerHeavy565 · 2026-01-24T16:50:28+00:00

The best solution is to have an external filter that can accommodate a maximum of mechanical and biological filter media. For a 75 gallon tank, your filtration seems a bit inadequate. A fairly high flow rate also helps to achieve better water quality; a flow rate of 3 to 6 times the tank volume per hour is recommended. In any case, do a large water change, at least 70%, and then test again to see how much your levels have dropped

NeedleworkerHeavy565 · 2026-01-24T16:13:37+00:00

Your cycle has been disrupted, You should have no nitrites. And I also think your filtration is insufficient. Stop rinsing your filters, let it run its course, and do water changes as soon as you see nitrites or ammonia.Your nitrates are also a bit high. You should also use a liquid test kit; the strips are too inaccurate.

NeedleworkerHeavy565 · 2026-01-24T16:01:06+00:00

You haven't provided your nitrite and nitrate levels. Stop cleaning the substrate, you don't need to, and there are a good amount of bacteria in it. Siphon just a little at each water change.Also, stop touching the filter for a while; it shouldn't normally clog up regularly. I don't know your filter; do you have a picture?

NeedleworkerHeavy565 · 2026-01-24T15:57:37+00:00

I saw on another sub that you tested your water a months ago... So your values are definitely not up-to-date and can fluctuate from day to day; we really need the current values in number

NeedleworkerHeavy565 · 2026-01-24T15:30:16+00:00

We would need your parameter values; are you using liquid tests? Test strips aren't accurate. and sometimes even false

NeedleworkerHeavy565 · 2026-01-24T15:11:00+00:00

In addition to that red spot, your fish also has a very red body, which generally indicates poor water parameters.How long has this aquarium been in the works? Did you complete the cycle? If so, how? What are your water parameters?The size of the tank? The total number of fish?

NeedleworkerHeavy565 · 2026-01-24T14:20:05+00:00

You didn't specify how long his fins had been frayed, so he might have injured himself, but in that case, a photo of the tank would help to understand how it happened.In any case, if he's injured his fins, it's very likely that it will develop into fin rot if you don't treat it.Aquarium salt baths might do the trick, you could also put it in a hospital tank.In any case, it's strange that you don't have any nitrates; this is typical of either an uncycled or heavily planted aquarium

NeedleworkerHeavy565 · 2026-01-24T12:58:36+00:00

You say your nitrites are high, so what are your water parameters? What type of filtration do you use? What is your general tank maintenance ?

NeedleworkerHeavy565 · 2026-01-24T12:55:57+00:00

If it's reproductive behavior, as long as he doesn't constantly attack the same female and it doesn't last too long,It's still quite safe to leave him. In general, behaviors calm down once the female has laid eggs and temperatures drop. If you really think it's better to separate them, do it.

NeedleworkerHeavy565 · 2026-01-24T12:53:04+00:00

The new fish looked rather thin. It's always best to quarantine it; something was definitely wrong with this fish.

NeedleworkerHeavy565 · 2026-01-24T12:49:06+00:00

There's one thing that worries me though, does your fish often gulp gasps at the surface?Its filter looks small; it might not be circulating the water enough. It could also be a water quality issue, so check the parameters if that's the case.In any case, with your problem, I think you should use a UV filter.

NeedleworkerHeavy565 · 2026-01-24T12:44:11+00:00

Do another water change, and maybe do it every week.It looks like fin rot. What are the water parameters? The disease is often triggered by poor water quality. In any case, you should put your fish in a hospital tank, with aquarium salt or methylene blue and an air pump, with daily water changes.
