Thanks for the help...
1) The tanks is roughly 8 months old.. and it is acrylic
2) The tank is i belive 29L
3) I use RO
water from a pure water store
4) I have a powercompact smartlight with a CustomSeaLife Smart Lamp(s) (half 10,000°K
Ultra-Daylight and half Ultra-Actinic).
5) I dont know about how much flow i have though...I do know that i have a rio aqua pump/powerhead and an internal filter. Both help out with water flow/movement. I have the powerhead on the right side and the internal filter on the left.
6)Yes i have a protein skimmer i use one of those seaclone protein skimmers
7) The live stock i have are: Valentini puffer, purple firefish, bicolor bleeny, algae bleeny, and 1 banded trochus snail.
I think i need more snails ... also the brown stuff on the glass is crusty and thus why it is harder to clean off than the green algae. I think you are right about it being coralline because from time to time purple grows on the glass as well and it is also crusty. The hair algae is all over the rocks and even growing on my live sand. What can i do the get rid of the annoying green and hair algae that keeps on growing???
Also i was thinking about trading my puffer for a flame angel...Can you guys recommend some good species for a 29L tank???
Thanks in advance for anyone who helps me out with my problems, your knowledge is greatly appreciated. Thanks!!!
