Water parameters as of 10:00 AM EST
PH 8.2
Ammonia 0
Nitrites 0
Nitrates 15-20 PPM
Feedings: 1-2 times a day with flake.
25% water changes every week.

Please help.
 
As yer tank matures this will be less of an issue. You know what I do??? I bleach all my stuff with bleach and water for about an hour and then I let everything dry out for overnight and then I rinse well and put back into the tank. Everything is fine. When bleach completely dries out, it is inert! Cool huh??
 
Do you have any live plants in there? If not, cut down the light...there's no need for 10 hours a day.

Just curious, what are those pinkish fish in there with the red zebras? Couldn't get a good angle in the shots.
 
africans will pick at and eat the algae covering the rocks. Many of them are largly herbivorious species. Besides, the algae looks natural and will help control your nitrates and phosphates.
 
I agree w/slipknottin. On my mbuna tank I ran several times the light you have, 12hrs per day - to support algae growth on the rocks! The fish grazed it routinely - many/most of them are herbivores or herbivorous/micropredators - so it is "free" fish food, and more natural behavior. I certainly would not bleach the rocks.

It might or might not lower your nitrate levels, which I'd like to see a bit lower. That may depend on the nitrate level in your water supply.

Oh :) I thought that brownish algae was a bad thing :)
 
not at all, diatoms and other brown algae is a pretty good food source for grazing fish.

The rocks in my mbuna tank are getting covered with purple and green 'turf' algae. Looks pretty cool. :D
