"Check how old your bulbs are, see if your tank is in direct sunlight, is your tank over populated?, How mutch do you feed?, What are your params "include phosphates and sillicates", What type of water do you use?, How often do you clean your filters? Do you run carbon if so how long before you change it for fresh carbon?"
Snipe,
Bulbs are about 4 mos old, though I am leaving them on from about 9a to 9p, maybe that is too long? The tank gets some ambient light through the window, but its not direct sunlight. I have 2 small clowns. I feed them once a day. Ph is 8.3, Nitrite is 0, Ammonia is 0, nitrate is slightly elevated. I change the filter pad once a month. there is carbon in the filter pad. I have no idea about phosphates and sillicates. How do I test for them?
Thanks,
Tom
