Mourning

[Mandarin Gobby]

Hi Everyone :sad:,

Just wanna share my sadness. I just lost nearly all of my fishes where the remaining survivors of my tank are my hawkfish, firefish and a blue damsel. :sad: :sad: :sad:

The story goes like this, I decided to change the water of my marine fish tank because it was looking a bit mucky and to my standard it wasn't crystal clear and also my filter system needs some water changing too. Usually I just change about 20% to 40% of the existing water but I decided to flush 80% of the water. I used 50% tap water (with anti chlorine of course) and 50% flitered drinking water. After everything was done, all my fishes looked fine and swimming actively. But came this moring, all my fish died with the exception above. I was so dumbfounded and shock. I lost Nassy (Naso Tang), Do, re and Mi (3 Blue tangs), Sarge (Sargent Clown), Mandy (Mandarin Fish), Betty (Bat Fish) and Noddy (Gloden Head Gobby). Now I am mourning for my fish. Can anyone tell me what I done wrong?

I am still poundering if I should restock my tank again?

sounds like shock. i just did the same thing at work in desperation to save the coral units that my boss neglected and about half the corals died...this resulted in a huge fight about who was wrong(i think it was a little of both) and it resulted in me getting fired...im sure he'll call me back sometime or later lol....but who knows. the fact that the coral units were in a mucky state the animals wernt doing good but even though i took out the smallest amount of water and slowly toped it off with RO the stressed corals couldnt take the change form bad to good. the same happened with ur tank probably but on a more drastic scale. u removed way to much water and the fish went through shock and died. im so sry that it happened i know how it feels.....:sad:
just start up slowly again and let ur remaining fish adjust slowly and keep up a regular cleaning agenda.

The pH, salinity, temperature all have a hand in your plight.

I would recommend aging your water for a couple days with the right salinity and temperature of your tank and go slow. Use powerheads.

Slowly pump the water into the tank and have powerheads on to circulate the water.

I have 2 brute trashcans I use for makeup water and for water changes. I use RO/DI water, a salt mix, a salinty tester, heater, and powerheads. Add the water first, then slowly the salt. Wait a couple days to allow the salt to dissolve completely. Having the temperature and salinity the same as the tank will reduce stressing the fish. Colder water can have a different salt content than warmer and will cause stress.

The first rule of saltwater tanks is going really slow.

I just wanted to say that I'm really sorry. That must have been devastating. I hope you will continue with the hobby despite the discouragement.
