Hi all

My system at home only has a 500 l volume of water and i lost one of my jade perch yesterday. The only thing i have done differently to my usual routine is that i added about 20% tap water. I have done this in the past with no ill affects. Any advice would be great full.

First does your water have chlorine
Also what is the rest of the tests

Include pH, ammonia, nitrite, nitrate and water temperature please... and what size are the fish??

pH 7.5
Ammonia 0 mg/L
Nitrate 0 mg/L
nitrate 20 mg/L
water Temp 20 c

10 jade perch approx 400 grams

350 l volume GB

I have a spare tube with water and an air stone. My system is large enough to handle water from the tap but I like to keep some water without chlorine around just in case.

One fish loss is not a problem, and not likely to be related to tap water, especially if it has not caused problems before.

I would not stress yet, but if you continue to loose fish every time you add water, you may need to do it with pre aerated water.
