Who Gives A Fish Forums

Thanks for the quick response. The tank's been up for about 3 months, and I feed once a day, just a pinch of flakes. Maybe I'm overdoing it?

My tank's been showing ammonia spikes lately, around 0.5 ppm, even after weekly water changes. It's a 20-gallon planted tank with a sponge filter, and I've got a few Neon Tetras and a Betta. Any ideas what's causing this?

I swear by Red Sea Coral Pro for my mixed reef. Alk stays steady at 8.5 dKH. Dry rock's cheap, so splurge on good salt and lights. My Radions are set at 60% intensity for 8 hours. Corals dig it.

My LFS sells 'pest-free' live rock cured in-house. Grabbed some for my 60-gallon and my Duncan's doubled in size in 2 months. Tank cycled in 2 weeks. Maybe try a mix? Start with dry, then add a piece of live to seed it.
