Dying tetras

[Gkopka]

I have a 30 gallon aquarium with 5 mollies, 7 glo tetras,1 5,black skirted tetras goroumi. Ph is 7.8 ,0 nitrates. Was noticeable cloudy water treating that but now my textras are suddenly dieing off now theres only 4 glo tetras, and 3 black skirted tetras . Its happened over 4 days ,was only 1 a say until today i lost 2 of the glo. I'm sending a picture of my tank its been up for about 1 month. I'll take more pictures and add them

0mg/L of nitrate in an unplanted tank seems off... can you test for ammonia and nitrite too? The cloudy water, the fact the tank has been set up for only a month and the lack of nitrate all suggests the tank is still cycling, therefore I’m curious as to what ammonia and nitrite could still be present at this stage.

Also the mIckey mouse platy in the picture was retuned to store because he was bullying all the fish in smaller tank i have

I'm attaching more photo. All so this is a new tank

I did ammonia test I dont remember the numbers but it was in normal range. The nitrate levels might not be 0 but in normal levels. But what ever is happening it only the textras

If we don’t know the exact readings of both ammonia and nitrite then there’s not much I can do. The tetras will likely be the first to die when a problem arises and here’s the reason: domestic strains of tetra species have become weaker with time and, in some cases, overbreeding. Glofish are genetically modified in ways that sharply weakens them and shortens lifespan. The other fish you have are hardy to an extent, but the same problem that killed the tetras will kill them too, give it time.

I'm heading home here soon for awhile I'm going to check them all again . I'm going to pick up some Ph down before heading home see whats going on. I'll post my numbers

I wouldn't personally worry about lowering your PH. 7.8 should be fine for your fish.

Ammonia and nitrites at 0 or as near as you can get

The problem is pretty simple - the tank is not cycled. Make sure you use lots of dechlorinator that also makes ammonia safe.

You need to read up on a fish in cycle.

Ammonia reading zero doesn’t mean anything if there was nothing ever in the tank and you weren’t adding ammonia to cycle it. Nearly all city tap water will read 0/0/0.

Ok , I'm finally ableto send readings ammonia 2.0ppm, nitrates between 5ppm 10 ppm, high ph 7.2 ph 7.4
Heres the rest would let send more all dine with API master test kit
I really dint know whats going on I've lost all tetras including glo ones and now one mollie

I've cycled it added API quick start . It stated with bacteria bloom thats cleard up. I've got a 10 gallon tank that has 2 guppies and 4 fry plates that are older should i move them to that tank ? Oh and 1 goroumi

It looks like you are in the middle of a fish in cycle. With that amount of Ammonia (in my opinion closer to 4ppm rather than 2ppm) in the tank it is a death trap for your fish.
Do you have Seachem Prime?
If this would be my tank I most likely would do 3 50% WCs during the course of today to bring the Ammonia to a survivable level (1 wc to 2ppm, 2. wc to 1ppm, 3. wc to .5ppm). Monitor the parameters daily and with waterchanges try to keep the Ammonia (and Nitrites combined for that matter) under 1ppm.
What kind of filter do you have in that tank?
