White spots, but not Ich??

Deezil

Hello Forum!

I recently had to move my tank so i had to remove 60% of the water and replaced with new. I have a 20 gallon tank that was in pristine healthy condition for over a year, until i moved it. I replaced the water and added the appropriate amounts of chemicals and aquarium salt just like i do with every other sucessful water change. More than half my fish died abruptly and unexpectedly.


My community consisted of:
2 sm Clown Loaches (now dead)
2 sm Bala Sharks (now dead)
1 md Dalmation Molly (now dead)
1 sm pictus cat (now dead)
2 md Chinese Algae Eaters (remained healthy)
1 sm Tiretrack eel (4"-5") (remained healthy)
1 md Gold Veil Angel (remained healthy)

I have always fed a combo of frozen blood worms, algae wafers, flakes and granules (not at the same time of course.) After i changed the water i purchased a pleco and about three days later it died. Two days after my bala's developed a milky/faded look and eventually their eyes clouded up. They lost thier appetites then started swimming like they were sick and they died. I couldn't really tell if they had spots or not. The loaches followed suit but they developed small white specs first. The Algae eaters and Angel were not affected at all, no spots, discoloration, or odd behavior at all. The eel is ok too, but it's a bit faded. This all happened over about three days.

on the second day, i treated the tank with API's super ich cure. I followed the directions EXACTLY and even removed tha carbon for the treatment then replacing with new after 25% water change. It's been two weeks now and i bought some new fish to test:

1 sm loach
2 sm balas
1 mystery snail
1 rubber pleco

It's 4 days since i put those fish in and the eel ate the two Bala's :( THe pleco and snail seem healthy, but the loach has the tiny white spots now and is acting like he's about to die.

My tank stays at about 82-84 due to the hot weather here in texas (which is supposed to be too warm for ich) and i did the treatment like i was supposed to. I take good care of my tank, it's clean and well maintained so i don't understand what's killing only some of my fish. Most of my readings are high since the 60% water change. Could I have poisoned the tank with tap water?

Nitrate 60 mg/L
Nitrite 0 - .25 mg/L
Hardness 200 ppm
Alkalinity 300 ppm
pH 8.2

PLEASE HELP!!

Hello and welcome to the forum!
Thats a lot of fish for a 20 gal tank. Can you tell me how the water test for ammonia?

Deezil

Well the test laoch just died, he was alive a few hours ago. I can see some discoloration on his black stripes and his gills look a little red and shiny but the white spots disappeared right after he died.

Deezil

Yeah it's a lot but they were all really small, about an inch, except the eel and angel. They were doing great until i moved the tank. I have test strips that tests for what i listed but no ammonia test. I'll get one tomorrow morning at petsmart. Anything else i shoud pick up while i'm there, should i test for anything else?

Twistersmom

I am thinking ammonia poisoning could possibly be the problem. Let the store run the complete test for ammonia, nitrite, nitrate, and PH. It will be nice to compare the results with your test strips.
Have them write down the exact levels of each and post the results as soon as possible. Once we have that info, we can go from there.

Fishin Pole

i agree with Twistermom.....sounds like ammonia poisoning, also with nitrite at .25, that could be contributing to some of the issues you are having....It sounds like you might have put your tank into a mini cycle.....How long did you have the fish that died in the tank?........I know you stated you had the tank for a year, but the bala sharks could not have been in there for a year and still be small.....They grow realtively fast for the first year of their life.... ....Exactly what chemicals did you put in when you moved the tank?........What is the water conditioner you used?........For right now i would not add anything else till your tank stabilizes and you have water test readings for us to determine which route you need to go..........I hope you do realize your Ph is high for some of the species you would like to keep is rather high

Deezil

They did the tests for me but they used strips too. Readings are similar.

Ammonia .3
Nitrite 0
Nitrate 60
pH 8.2
Alkalinity 170-200
Hardness 200
Chlorine 0
Current temp 82-84

I know the pH is high but is that caused by the high nitrate level? I wasn't exactly talking to an expert at the store.

Deezil

none of the fish were very old, only the eel and angel. I realize the tank was probably getting crowded but it hasn't been for three weeks and i still can't get the readings back down to healthy levels. I vacuum gravel and 25% of the water every week and replace with tap water treated with stress coat and stress zyme.

Fishin Pole

with those results on your water test, i suggest you do an immediate water change to get your ammonia down.....please invest in a liquid test kit, this is the best investment a fishkeeper can purchase early on into the hobby........once the water change is done, i would then wait 12 hours and retest your water and see where your levels are at.........with ammonia at .3, your fish are sucumbing to ammonia poisoning and will continue to degrade till you can get that to "0"......Also test your water coming straight out of the tap........please keep us posted on your results

Twistersmom

Good advice from Fishin Pole, Just thought I would add to it. That ammonia level is enough to kill your fish.
Ammonia does not raise ph. The ph from your tap might just be that high. Do run a test for ammonia, nitrite, nitrate, and ph on the tap water as well. Post the results.
You may need to do daily partial water changes to lower the ammonia. Your nitrates are also at an unsafe level. If you feed the fish less for a while, along with the water changes, it should help in getting ammonia and nitrate under control.
What fish are currently in the tank?
If tank remains heavily stocked, weekly water changes may never be enough to keep ammonia, nitrites, and nitrates under control.
Do go buy yourself the API liquid freshwater testing kit. Keeping a well stocked tank, it is so important to test your water frequently. The API test is a Little pricey, but it will last a long time.
