OK... lets see where do i start... i know i haven't posted in a while but that was only b/c i thought things were going well in my tanks, but apparently i was wrong... I have now lost 4 fish, my gravel has turned brown and algae is begging to take over the back wall of the tank.... It also has a smell which is better now that i got rid of the floating plants i had but it still makes my room smell... the fish i believe to have died from dropsy, only one has shown the pine cone effect but i am afraid that i will lose the rest of my fish! Please if you have any advice please let me know... i have currently replace the gravel leaving the original water in the tank, i have treated it for dropsy and for algae control.. is that good enough? any help would be awesome!

When did you last test your water and ow often do you change it?

Well i made the mistake of thinking everything was OK and haven't checked it in a while... and i do a water change like every 2 weeks.... but i have lost 4 more fish, so i fear that it may be too late....

From the description I would guess your nitrates are much too high. Though it may have mini cycled on you as well, definitely need more info in order to help.
