MY view is that it turns your fish into wimps and they become reliant on it rather than building up their immune system As regards LR as long as you have added the minimum ammount reqd, any extra is a bonus mickey 2009-01-07 http://forum.aqua-fish.net/?topic=live-rock_#3 hey i wanna know what would be the best way to filter............well i am using a glass filter.......and i am facing a problem of water becoming yellowish in colour after a few days of changing the water.....i asked the lfs he said it is due to feed {tetrabits}any suggestions... surya_kant13 2009-01-07 http://forum.aqua-fish.net/?topic=live-rock_#4 could be the food as I use Tetra Prima for the discus and it stains water, because I do daily water changes its not a great problem for me.
