Weird Water Color & Surface Foam

[ArroWanaWhitey]

The water in my tank has turned redish. It started after i took out the filters to apply medication for fin rot.. The water changed color to match the color of the medication... and then when i put the filters back in it stayed kind of a dirty lake color... and on top of the water there is foam... its like the foam you see on the shore at the lake.. i have to remove it with the net... it only is forming on the surface in front of where the filter poors water in.. i can still see the fish and plants and all that good stuff.. but its really bothering me having unclear water... how do i fix it?

What is the manufacture name of the med.
Have you increased aeration in the tank.
How are the fish acting?

Meds are called... T.C. Tetracycline... All the water parameters are good.... The fish are fine.. one angel fish did die with no explination.. but all the fish are active and healthy.. the water is just an odd color and the foam keeps coming back...

A polishing pad in the filter will help some. I have to use them when removing meds. It helps clear the water quicker and helps stop foaming. It is worth a try.

You do know that tetracycline will wipe your benefical bacteria out in the filter.
Have you increased aeration in the tank as water can go frothy when not much aeration.

I would add some carbon to your filter to now remove the medication especially if your bacteria in the filter is at risk.Then do regular water changes at regular intervals but not too much at once because if your bacterial population in your filter is down it may have too much to cope with with a big water change.Perhaps 10% a day until the medication has gone.
