Re: Cloudy water

Dave asked about clearing up some cloudy water / GW from his tanks: (some parts snipped)

I have found that those type of bulbs are usually pretty worthless -- much lower lumen output.  I would either replace all 4 or atleast 3 of them with something more akin to a 5000K or 6500K spectrum.   There is lots of goof lighting info on the Krib and in the archives.

No, you shouldn't.  Do you eat the same thing for every meal?  Probably not, so don't make your fish!!  Also, I would recommend you "thaw" the frozen cubes in a little cup before feeding.  Tropical fish don't eat still-frozen-food in the wild, so they shouldn't in your tank either.  Also, I would seriously consider feeding some live foods as well.

Next to the trickle filter is a mag 350 (hand-me-down from my >father, I hoped the extra filtration would help) with a pleated filter with a sleeve.

This all sounds pretty good. 

>An additional 55 oz. laterite on top of the mix in the back-half, making a thin layer of laterite >before about 2-3" gravel. 

This could be a problem -- laterite is really meant to be covered with gravel to reduce the availability of the Fe to the water column.

It would help to know the exact plants...  Perhaps you could check around the web and get some IDs?  Some might not even be aquatics, and that could be part of your problem.  It doesn't sound like you have enough plant mass for that large of a tank.  Also, how old is the tank?

>All the swords came in pots and I left them in the wool. 


Again, not a good idea.  There is usually a lot of nutrients in the wool and that can then be available to algae in the water column.

There's another problem -- not enough CO2 for the amount of lights.  That = bad plant growth and good algae growth.
Hmmm... You may want to reconsider some of your fish choices or decide if what you are after is a "planted tank" or a "fish tank with plants".  You definitely need to do some homework... I am not trying to be a jerk or anything, but you didn't say anything about water changes, parameters, etc.  Have you done any water changes?  How many total fish / size do you have in the tank?
It is hard to give advice on preventing algae without more detail.


>With all that, the fish seem very happy (all but the puffer). The angels 

>have HUGE fins and nice color. My earth eater has nice irridescent spots all over him and >beautiful spike fins, none tattered...all the fish are 

>happy. HELP! 


That is pretty subjective... I think they would be happier with a more varied diet.

Hope some of this helps,
