i will go for 100% cree led lighting. I think the sponsors here bring in some good LED lighting or to save some bucks, you can get a decent sec hand one.

My buggy reef controller codes. I have taken this down for the time being as there are some bugs with the program and I am too busy to troubleshoot.

1) Latezonatus Pair + RBTA home ---- $800 Captive Bred full bar pair that i have kept for well over a year. Pair is also exhibiting spawning behaviour. Female latz measures close to 3". RBTA opens up to palm size and is anchored in a clam shell which prevents it from moving around and also allow easy placement to whichever corner you like. 2) Snow basslet (Serranus Chionaraia) ---- $500 Fish measures 2". Eat pellets, flakes, mysis and anything that drop into the water. 3) Redsea Eightline flasher wrasse (Paracheilinus Octotaenia) ---- $200 3" male. Eating pellets and flakes and anything that drop into the water. 4) Chaetodontoplus Poliourus (Reserved by Bro Eniram) This is the only piece available in singapore! Very rare angel! Eating pellets and flakes and anything that drop into the water.
