Cycling without water change?

Well, I'm on day 12 of cycling package part 1 in my new 110, and I've still not done a water change. Except for the first 24 hrs, when there was a barely measurable ammonia spike (less than .5), the parameters have been consistently 0 ammonia, .1-.2 nitrite, 5 nitrate (I'm not checking nitrate daily, as it didn't seem to mean a whole lot until the nitrites are 0), pH 8.1.

Do I just let this continue, working on the "if it ain't broke, don't fix it" theory? I'd hoped that the nitrites would drop to zero within a few days of the ammonia, but that hasn't been the case.

The tank looks great... happy critters all over the place. There's still sponge die-off, but the crabs are doing a much better job of cleaning that off the rock than I could. Counted at least a half dozen of the guys happily munching away this morning.

No need to test nitrates every day, esp. at these low numbers (5ppm). Yes, do wait for the nitrites to drop to zero. They will. Just takes a bit of time for the bacteria to reproduce.

Don't fix til broken is absolutely good!

Pictures!
 
Still trying to get some pictures, but for the life of me, I haven't been able to figure out the focusing and exposure setting I need to use for tank shots with my new camera. "Normal' photos are a snap.
 
Dave,

Turn on all the lights, turn off the camera flash. Use a tripod if you've got one, otherwise, lay off the coffee before taking the picture.

Autofocus can get confused, try to aim at the edge of a rock or something that's contrasty to help the autofocus.

If you want to play with setting the exposure yourself, set the camera to aperture priority, and choose a smaller aperture (larger f/#, e.g. f/4 is better than f/2; f/5.6 is even better) to get more depth-of-field.

That's just generalized guidelines.

well it take time.. that's the patient u got to have on marine...
once your cycle is complete it will be best to have a 10% water change be4 you start adding LS
