One of my fish die roughly every 10 days
I have a 360 litre tank with nitrate, nitrite and ammonia at 0.0 and PH 8.3 temp 26 (in green band) - this shows as normal for all of them
I have two filter systems - orignal jewel system and a EHMI system.
I have tried varoius frequencies of carrying out water changes about 80 litres every week or fornight.
I change the filters as recommended
I do have plants so weekely add plant food
I feed them once a day 6 times a week
Why is this happening?
Also another question, I recently when I saw a few ill, tried adding salt. Is this ok?
Can anyone help me - I am a newbie!
