Howdy,
I recently (~2 months ago) purchased a used 45 gallon setup. Shortly after getting the tank I decided to ditch the plants/gravel/substrate that came with it. I thought it would be neat to have a forest of twisty bamboo (I believe it's also called "Lucky Bamboo"). So I completely cleaned the tank, replaced the old gravel/substrate mix with straight up gravel and planted the various stalks of bamboo.
I initially had the setup running on a 12/12 light cycle, but after a few weeks I noticed that the tips of the "bloom" part of the bamboo were turning yellow. Sure enough it kept progressing so I decided to slowly add more time to the light cycle bringing it up to 18/6. It's been on 18/6 for about 2 weeks now and they've stopped yellowing and are in fact growing well. pH stays around 7.5ish and the temp is around ~80.
I've tried searching around but I can't dig up anything on this bamboo to see if other people use the same light cycle. My other concern is that all this light might negatively effect my fish. I can't seem to find a *concrete* answer on what the correct light cycle should be - there's conflicting answers everywhere I look.
So far all of my fish seem to be fine with the extra light, the only exception would be a Bamboo Shrimp that I purchased last week. He died out in the open(on his back) about 3 days after he was in the tank. I know there's several things this could be but do you think the light would have anything to do with that? I tested for ammonia and that's all good.
FYI, the tank has:
1 yellow rainbow
1 australian rainbow
1 angel fish
1 silver molly
1 silver dollar
2 true Siamese Algae Eaters
1 butterfly pleco
3 Pristella tetras
Thanks in advance for any input/advice.
