Matt are these fish that you recently bought, or have you added any new fish to this tank.

Have they turned very dark, especially the one with the white cobweb like film over it.

Do you have a water hardness test kit, and if so, can you tell me the hardness. You may have a problem with either the gravel or rocks in the tank.

[dismatt]

dont have a hardness nest kit but the ph seems to go up all the time the fish that are sick are two weeks old all others ok the rocks in the tank are coral peices and the plants are fake. thanks for all your help ladyred

[dismatt]

sorry the base of the tank is sand everything goes wrong why me.

problem found! take that coral rock out!!! shells and coral (all stuff that comes from the sea) make your hardness skyrocket up and they also buffer the pH up too. take it out imeadiatly and do a 50% w/c. only use clorine neutraliser (dont worry about any ph buffers to put it down yet). go to your LFS and but some triple-sulfa. this will stop them getting any infection. i think somehow the 1 with the white film has gotten damage to his slime coat or it has been burt off. also o to your grocery store and buy some NON-IODISED salt (pure salt). i can remember the dosage for salt right now but you will need it. i will try and remember and get back to you about it. the triple-sulfa will need to be in the tank for 3 days and then do a 1/3 w/c. then re-dose the AMOUNT OF WATER YOU CHANGED with triple-sulfa. you need to keep the triple-sulfa in there while they look bad.

hope this helps!

i also forgot to tell you:

while your fish are sick you need to slowly lower your ph down to atleast 6.0 DONT PANIC as i said SLOWLY!!!! lower is better. while the ph is so low 2 things will happen:

1. below a ph of 7.0 ammonia turns into ammonite (i cant remember what it is called). ammonia is 10 times more toxic than its form below 7.0!!!! this is why the ph must be quite low!!!!! so while they are ill they are succeptible to the toxicity of the water (as i said before i think the slime coat is burnt off of them). so try and keep it low if possible

2. with a ph so low the bacteria in the filter will start to die off! this will be a bit of a problem in the longrun. however there is a product called aqua cycle and it is made by science products. this product will restart your bacteria colony again. use the aqua cycle after you have completed the triple-sulfa course and you have brought the ph up again.



now i have just thought of something:

have u bin using ph down to lower the ph?

the coral has stopped the ph from going down and there might be a build up of ph down in there. if so it will bomb the tank after the coral is taken out and we have a problem.

do the 50% w/c and make sure you get the triple-sulfa!!!! if possible get the other fish into a different tank especially the black ghost knife fish because it is a scaleless fish.

it is imperative that you test the ph at least 4 times a day and if you notice any changes POST IT STRAIGHT AWAY!!!!!!!!!!

im remembering a couple of things that could also help you:

feed the fish very spaingly because any poop and uneated food will cause the ammonia to build up. the discus arent in any shape to fight very much right now so you need to do as much as you can to help them out

[dismatt]

when i got home from work thediscus with the slime mucus over seems alright its just the other which stays in the corner both of the lrg dicus fins seem to have frayed alittle what could that be also took out the coral rocks and did 50% water change check things after ph 7 ammonia 0ppm nitrite 0.1mg all other fish sem happy is the temp ok at 30 have cannister on and internal filter aswell as air stone have carbon in internal filter only is that ok. thanks heaps for all your help.
