nope I didn't QT him and theres no warranty sadly cause the store I bought it from doesn't give refunds or credit for any reason on saltwater fish
I decided to stick to this hobby but i am going at it really slow this time around and i have 2-3 questions i'd like answered
1) does the emperor 400's bio wheels add nitrates back to the tank over a period of many months or ?? ( i cleaned mine with freshwater ) are they really needed or can i just lose them ?
2) if i do a 50% water change with the cycled water in the tank and cured live rock would it affect the water chemistry in anyway ?
3) if i keep my nitrates lower than 20 at all times i shouldn't see a fish die due to poor water quality unless the fish was unhealthy to begin with ?
thank you all
edit: i tested my freshwater source aka tap water and to my surprise it's 0 nitrates so i can rule that out for raising my nitrates so the only thing left would have to be possibly the bio wheels on my emperor 400 or the sand bed ( i used sugar fine aragonite sand over crushed coral )
1. Yes bio wheels can add nitrates if it gets dirty and not cleaned and changed out as needed. If you have enough LR in the tank there is no need for it anyways. Just take the wheel out and let it run for flow. Also how much flow do you have?
2. 50% water change shouldn't hurt anything. Just make sure it is to proper temp and PH.
3. As stated above fish can tolerate high trates. It would take alot for it to kill a fish. Your fish could of had an internal parasite to begin with.
The crushed coral can be a problem.
As stated also. Many of the fish you had die was probably caused from the tank being to small. Tangs, triggers, puffers don't belong in a 55.
