Let me suggest that you look into a brand-new product called Bio-Spira. Read up on it at
www.marineland.com I've been following articles by this guy Hovanecs for years and he's trustworthy. Later you should read all his articles archived at that site.
Let me suggest that you look into an ammonia-sequestering chemical called AmQuel put out by Kordon. It will give you false positive tests for ammonia, but it locks the ammonia in a form that's non-toxic but available to the nitrifying bacteria you are soon to know more intimately than any except
E. coli!
Let me suggest that now, before you throw away all the packaging, you take the unused undergravel filter back to the lfs-- for credit, not a refund. Trade it in for a bag of red Flourite to mix with your gravel. Later you may want to have real plants. Meanwhile the laterite will help stabilize phosphate levels etc.
Let me suggest you get David E. Boruchowitz,
The Simple Guide to Freshwater Aquariums.
www.amazon.com could have it in your hands before the weekend.
Let me recommend that you bookmark
www.thekrib.com for constant reference. Read the FAQs there now. Read all the rest of that site tomorrow!
Let me suggest that you avoid neons, with your alkaline water. Go with some Barbs or Danios for now. Better get the website for Toledo Water Dept. and work out what the alkalinity (KH) of your water is.
...and take an old man's advice, move slower and work each step out
together.
