I'm usually the type to have plant/shrimp-only tanks, but my wife has a common goldfish that she's had for longer than me—just under 8 years.
I got back from a trip a few days ago and found that for medical reasons she'd forgotten to do water changes for her goldfish's tank. I measured nitrates at ~40 ppm, perhaps higher, and ammonia at .25-.5ppm. The poor fish is already sensitive to nitrates from being poisoned before we were together, and she was very clearly poisoned now, curled up at the bottom of the tank.
I immediately dosed Prime at 3x the normal rate, added aquarium salt @ 1 tablespoon per 3 gallons, then started doing 5% water changes every hour, and got the nitrates down to 5ppm and ammonia to near-zero. (I'm continually doing water changes to keep this down; seems like her tank could've lost its cycle somehow.)
Here's my problem: It's now been just under three days since I started addressing the nitrates and water quality, and while she's moving a bit more, she's still curled up. I'm worried that she won't be able to eat any food i give her. (I haven't fed her yet; don't want to make matters worse.)
Would Methylene blue clear the bound nitrates from her system and let her uncurl? Is there anything more I can do to help her? I'm willing to try whatever I need to; I've come quite attached to this goldfish, to say the least!
Currently at work, but as soon as I'm home I'll add photos to help anybody that needs it for diagnosis!
TL;DR: My wife's goldfish has what's presenting as nitrate poisoning: curled up at the bottom. I addressed water quality issues three days ago, but she's still curled up and not moving much. What can I do to help? (Methylene Blue, perhaps?)
They are used to quickly stop bleeding, like chronic nosebleeds. Sometimes found in first aid kits, especially around athletic events. Pretty common for veterinary use. I can't seem to find them anywhere.
Edit: Found at Shoppers Drug Mart, Wolfville
our common goldfish is dying of nitrate poisoning. I need to know if we are doing everything we can or if there is something I am missing. 65 gallon tank. Fish is 9-10 years old. Has lived happily all this time (with initial tank upgrades bc he was in poor condition when I met him). Had not checked water parameters in ages (I know this is bad but he has lived fine for so long we didn’t think to check). Was showing signs of nitrate poisoning including lethargy, not eating, starting to stay at the bottom and eventually On side. Checked water parameters.
Ph- 7.6, Ammonia 0, nitrite 0, nitrates 160 (!!!!!!!!!). Of course I was mortified and immediately searched for how to fix it and did one 50% change and then 20% daily after that. Have been doing this for over a week now. Nitrate is now down to 10ppm and we are aiming for 5 as per suggestion in a goldfish Facebook group. We also fasted the fish for 3 days but he wasn’t eating anyway and still won’t eat now but I am not sure if it is because he can’t reach the food or not. We have tried hand feeding him peas but he won’t take it. We added an aerator because we did not have one. Apparently he lived this long without one until a fish keeper friend of mine said it could be a lack of oxygen.
Our fish is still showing all of those signs and in fact sometimes seems almost dead. I am devastated and know we fucked up so please don’t be mean about it, just looking for advice to see if we missed anything that should be checked to help him survive. Is it too late? I don’t want him to suffer.
Finally got myself the master freshwater testing kit and was surprised that my ammonia, ph, and nitrites are great but my nitrates are BRIGHT red. Its a planted 20G long, I have 7 tiger barbs and 3 corys. They are all established and seem fine but over the last month I have been wanting to get some ghost or amano shrimps to deal with some gunk in the tank but I want the tank ready for them.
I had been doing weekly (ish, i have forgotten a few times) 1/3 water changes because I couldn't get the damned ammonia under control. Turns out my old water test kit was crap because I did a side by side test and cheap test still says I have bad ammonia, master test says its fine. (I redid it twice just in case I may have buggered the first test somehow.) But my nitrates are BRIGHT stinking red and I was worried about it.
I read that my tap water may be the biggest culprit. I do use prime conditioner in my change water but is there something else I can pretreat my change water with so that there are less nitrates? Also I have those little ceramic nuts (little ceramic cog shaped things) in my filter instead of the disposable bags and a friend told me to NEVER change them because that is what holds my good bacteria, but online I read that I SHOULD be rubbing them off in treated water every now and again to remove algae or anything else that may have grown on them. Should I start by cleaning those off?
I am cycling a new system. About 4 weeks in I started to see Nitrates in the tests. For about a week Nitrate levels slowly increased as expected. It got up to 10 ppm.
Then the last 2 days the Nitrate reading has been 0 ppm. I haven't changed my testing procedure as far as I know.
Is it possible for Nitrates to disappear in a system that is just cycling? Or is something else going on?
I did put some ph down into the system during the last week to slowly lower pH from 7.4 down to 6.7. That is the only addition I've made to the system in the last week.
Help! I've been having issues with nitrates and realised that my tap water gives a dip-test reading of about 40ppm nitrate... Which is what I've been using to do water changes. I always wondered why I had troubles with nitrates even if everything else was perfect! Aside from using RO water, which is not an option for me at present, what can I use to help remove it? I have 3 tanks totalling >400L capacity and only 1 is planted. Ideally something for the filter or something to add to each water change.
I came up with a simple system for water filtration, 1 bucket with gravel, sand and charcoal, and below it bucket 2 with Berkey filters. This is cheap, no electricity, simple and doesnt require expensive filter replacements or systems to power.
I want to make sure PFAS and Nitrates are removed from my water. Charcoal should remove PFAS, but I am unsure if Berkey filters remove nitrates. There site claims it removes 95% of nitrates (https://www.berkeyfilters.com/pages/filtration-specifications), however other sites are stating this is not true and because Berkey wont prove this, they are banned in Iowa / Cali (https://ccbw.com/blog/the-truth-about-berkey-filters-why-theyre-not-right-for-iowa/)
"Nitrite and nitrate levels must be regulated in drinking water because they can cause serious health problems, especially for infants. Berkey’s claim of removing 95% of nitrites is not possible due to their climate and purification type. Nitrates have been in the local news a lot lately, given the pending litigation Des Moines Water Works is pursuing against three northern Iowa counties. Berkey uses carbon filtration to purify water; however, according to the EPA, the only treatment methods proven to remove nitrate from water are ion exchange, reverse osmosis, and electrodialysis."
Question: Does Berkey remove nitrates?
i have 30l shrimp tank, with about 5 cherries, and the nitrate is always around 80. the ammonia and nitrite is 0, but i can’t seem to get the nitrate down. i tested our tap water and the nitrate on the was just under 80. any advice on what i should do to get this down?
