I just got more LR with many different growths on it. The color is all different colors, so that helped a lot. I didn't like the LR look, but I just think I need more of it. I now have 21# and I filled up the back of the tank which looks very nice. My Nitrites are back to 0 and the nitrates are to 5, so I think everything is a ok. I still have the brown alge. I used my well water, so I will switch and buy it at the store for my water change.
I did hear the sponge is very hard. I really like the coco worms, but I read they could be hard to care for.
I will build it slow and before buying any thing else I'll do more research. I got a little over whelming looking everything up, so I'll do one at a time as I go. I feed brime shirmp to the fish every other day so with the tube anemone's that wouldn't be a problem. I'm still looking for what I may want. I did read the tube anemone's can be a problem if I go to a reef tank, but by the time I would go to a reef tank I will than buy a bigger tank. I still have a lot of learning to do. I am enjoying it though.
