Quick Question

[advice1]

Ok, so my nitrites and ammonia finally went to none, so I did a water change to lower the nitrate level. It didnt lower it much(because I was doing the test wrong.. put 2ml instead of 1ml in the vial..reading DOES help) so I decided to change the water again. Same thing happened so I changed the water again.. and then again, and now that Im doing the tests right it is finally lowering off. My question is that did I do too many water changes in too little time.. and will this mess up the balance in my tank.

Here are some pics, little 9g nano(dont know if they are going to link properly, but I'll give it a shot):

Last photo is a little blurry, and sorry Im using my moms cr*ppy camera


Thanks for your time.

No problem. The bacteria that will control nitrogen are growing on the rock and sand. Very few are in the water column.

IMO, you can safely do up to about an 80% water change with no ill effects. Unless you're water source is bad. lol.
