How long to wait after doing a water change?

How long should you wait to test your water after changing your water? I just did a 7 g change on my 46 g and the high nitrates remained the same.

 

So if your NO4 was at 25 a 7g water change would put them and 21ish still really high.

 

longer! lol! give it time! the cycle aint done yet!

 

man, you just added those fish without waiting for the cycle to complete? your nemo's may make it but doubt the cardianl will! i'd get some more water ready ASAP! patience man!

 

Plus one.
You have to wait 100% in this hobby. My tank is 6 months old and I'm just adding my 5th coral and 4th fish now. It's a very slow process

 

dude ya gotta be honest a forthright in this hobby to allow those to help ya right! ya shouldnt have added fish with those parameters! Ya should look into getting some dr tims all in one or microbe lift ASAP!

 

Nitrate levels in a marine aquarium never be above 15 ppm I guess. Ideally you want a level of 5 ppm or below. I think that you will be alright, but I would continue to do 10% water changes every day or so until you get the nitrates down. Good luck. You can try and get some seachem purigen as well, that should help.

 

i'd still get the water ready! My fishy's dont like high nitrate!

 

Lol, that is why I suggest 10% daily water changes. He isn't to far off though from 15 ppm. A couple more water changes should really help along with running something like purigen, or any other filter media that will remove nitrates. ;D

 

If you have a refugium I'd get some chaeto algae in there asap as well
