Well, tested my water in the 220 today and the Ammonia is at 0, Nitrites are at 1.25 ppm and Nitrates are 5.
For some reason the nitrates in my 55 Silver Dollar
tank are through the roof again. Tested the water on Thursday, they were 80 ppm. They're usually around 5. I've never had them that high in any tank before. Never had them above 20, and the only time they went to 20 was when I went two and a half weeks between water changes once in the summer.
So I did a water change Friday, tested it today and it's still around 80. What the heck?? Zero ammonia and nitrites, thank goodness. So I guess I have to start doing larger water changes? I usually do a quarter. Maybe I'll try a third.
Finally, checked out the bulbs at my local Big Al's today. The only bulbs they had rates 6,700 K were T5s, which are no good to me. The had Aqueon Full Spectrum Daylight 25W bulbs, that did not rate the K on the package. I got one of the employees to double check in case I was missing it, but he didn't see it either.
So I checked Pet Smart's website and they list the Aqueon Full Spectrum Daylight 25W as 8,000K. On their site you can actually see it on the box, but it was absolutely not on the box at Big Al's. I think they're the same bulb though.
Is 8,000K ok, or do I need 6,700 K?
