Cloudy overnight!

[skywylie]

Current tank:
26G Tank setup over 1 year.
10 Neon tetras
2 Rosy Barb
3 white fin tetras
No mollies after the few died 1 by 1 a couple months ago.

So yesterday I’ve changed about 15% water, normally I just use tap water, put the recommended amount of water conditioner(as indicated by the bottle), and let the bucket sit for a couple nights as a precaution as well. I’ve been doing such for over a year now and all seems well except having a hard time keeping livebearers to live more than 9 months/a year.

So, taking the advice from the LFS guy, perhaps the tap water that I change everytime has some ammonia which slowly poisoning my more delicate livebearers(but not the hardy tetras)? And I should change a little more water each time as the nitrate might also contributed to the cause of the livebearer dying so soon(I checked, 20ppm only)

So this time, I put enough water conditioner into my bucket of tap water to ensure no ammonia(ended up 2 or 3x more than before and repeated water tests) before putting into the tank…and voila!! Overnight I have a foggy/cloudy tank. So cloudy I can bearly see my fish! First thing I tested the water, everything is good, 0 ammonia, 0 nitrite/nitrate, PH level as usual/before…But 9 of my neon tetras died because of that!! At first I though my heater broke or something, as there is some sort of smoky, burnt smell. But after close inspection of the equipment everything’s fine…

My only conclusion would be bacteria boom? maybe cause the tank was used to being fed with some “ammonia” before, and this time a sudden lack of such ammonia in the water I put in might have caused this?
Only 15% of water changes this time can cause such imbalance??
Would it be better to stick to my old water change routine and just use ‘enough’ of conditioner for my tap water (tho there would still be some ammonia in it)?

My other dwarf puffer tank have a pleco and some dwarf puffers in it, and seems like my dps are short lived too(3-6 months), maybe I wasn’t doing the water change right? But my pleco in the DP tank which is 1+ year old now…and recently with a new gold nugget as well, I’m scared of changing the water of my DP tank now!…and I thought I have 2 well established well setup aquariums!

What went wrong?

Thanks for all your help.

So, after 24 hours, this morning when I wake up, all cloudiness gone...

I changed about 20% water right away yesterday morning, I guess that helped...but what really bothers me was all my Neon tetras died from this incident...all the Rosies and white fin tetras were ok.

It could be a bloom or when you add water in the fish tank the cloudyness comes from moving debris around in the aquarium. Test your water prior to adding to the tank fromt he tap and see if there is ammonia in it as well

[skywylie]

Yes, I think it’s actually a bloom, just checked last night, and ammonia is quite high, I might have a mini cycle…

Anyhow, seems like I have to add like 1/3 of a bottle of water conditioner to get 0 ammonia from the tap water, this doesn’t make sense. I know too much conditioner is not good either, so I usually just use as directioned by the bottle, even tho the tap water still have some ammonia in it, and sitting the bucket over night or over few nights doesn’t reduce ammonia either…. anyone has any suggestions for water conditioner?

Thanks.

also make sure if you are changing water in your aquarium never change the filter the same time as you lose to much benificial bacteria.
