I am an extreme newbie (I dont even have fish yet) and this is my first posting. I have followed the forums, read and researched aquarium keeping for the last 6 months because I want to be successful at this hobby. However, my first mistake was to introduce driftwood and corkbark into my new 60-gallon aquarium too soon. I soaked the corkbark for a week and dumped out the brown water (first red flag ignored) and siliconed it to the inside back of my tank. I also soaked two large pieces of mopani driftwood for about a month and a half, dumping out brown water every few days (second red flag ignored). I put ecocomplete substrate in the tank, arranged the driftwood, filled the tank and I guess the combined tannins from the corkbark and the driftwood are too much for my Fluval 305 to filter out (media is bio-maxx and activated carbon). My water is a deep "amazon" brown unless I change out 75% of it every few days. I guess I'll have to live with the color, but my question is: I have 4X55 watt PC tubes of lighting and I read on your forum that PC tubes are 1.35 times brighter than normal fluorescent tubes, so that gives me around 4.9 WPG. With the reduced visibility in the tank, can I keep low light plants happy? They are on order now. I'm also not sure how fish will take to the tinted water. If I had to , I could take out the driftwood, but the corkbark is glued to stay. Sorry for the long-winded narrative, I'll make future ones shorter. Any advice you learned sages can give me will be much appreciated. (haven't cycled the tank yet because of this; I have bio-spyra in the fridge waiting. :help:
