Maybe im just doing this all wrong! Poor little fishies. My nitrates have been between 10-15. Iv been scraping it off for now. Let me know if you have any suggestion on how I can improve the care of my tank:-) thanks.
Treated tap water might be ok if you have decent water where you live. RO is always the best but RO systems are expensive...I don't use one, personally.
If your tank came with a plain incandescent or flourescent bulb, then yeah, that could be the problem. I use power compact lighting...the T5 HO bulbs are best
. So definately get a stronger lighting system and make sure you get 50/50 actinic bulbs or two bulbs...a regular and an actinic.
And don't worry, I'm sure it isn't bothering your fishies
. Brown diatoms aren't going to harm your fish...they're just annoying to look at.
Since your tank is so new I wouldn't worry too much. You could add another snail or two if your tank can handle it but otherwise I would just scrape it off and get better lighting.
Do you have live rock and are you adding any supplements? Calcium will help corraline algae to grow.
But like I said, it could be your water, too. I have no idea how your water is. You can buy saltwater in jugs at some stores so you could always try using that for a little while and see if it helps. Instant Ocean is a great brand so I'm sure that's not the problem
You could also try vacuuming the gravel more...try to get your nitrates a bit lower. They aren't that bad but the lower the nitrates the better because algae needs nitrates to survive.
