Like you all know i set up a hospitaltank, that i use to quarantine my new Tiger O in.
I used a cycled filter and ammo and nitritestests read zero.
The tank is only 30Gl.
Now what wouldt you all suggest,testing for nitrates and doing waterchanges accordingly?
Or just change water 2-3 times weekly anyhow, like Nickysue suggested?
And how much water should i change at a time if i just do the wc without testing?
30% would be my guess now.
Of course i use dechlorinator and it seems i bought a Tiger with a big appetite.
I know that will add on the bioload, but his belly needs to be fuller than it is now!

well ive never heard of anybody changing their water too much noddy, i think twice a week, 30% would be just fine!!!
