I just started a planted fluval chi for a future "breeding tank" I used small pebble rocks for the substrate and planted a fairly healthy jungle. I figure the excessive plants (hosting beneficial bacteria) should help cycle the tank. I will probally throw in a bit of fish food for some added ammonia goodness.
IS there any other tips for cycling a heavily planted tank? I'm just using the stock chi filtration light/filter for now but may upgrade to a hob or sponge filter down the road. I plan on using this as a breeding/fry tank once its successfully cycled.
Check your ammonia and nitrates. I would put in some fast-growing tall stem plants (e.g., anachris) in the back. If your ammonia is 0 you should put in a fish or two. You should see if you can increase the light some. Maybe a clip-on lamp with a Compact Fluorescent light (10 watts, it's hard to say how much more not knowing the size of the tank)
Hope that helped.
