50% water changes
So, I just ordered some dry ferts from GLA (NPK+CSM&B) and I understand the dosing regime routine, but I am still skeptical about the 50% water changes.
I have a 10 gallon tank so I understand I'll be dosing about 1/4 tsp or less of everything, and then a 50% water change on [Sunday] or whatever day I choose.
Every time I've done a 50% (or more) water change to my 10g, I've lost fish as a result. Is that a side effect of the EI dosing routine? Do I need to be super anal about the new water coming in now?
Now granted, the particular experience I'm talking about was in my earlier experience in the hobby. I freaked out over the color of the dirty water and did a 55ish percent water change without checking the temps & I kind of dumped the new water in very quickly and lost a black moor & telescope goldfish a few days later.
Can someone ensure me that 50% water changes are necessary and maybe instruct me on a proper way to conduct them?
