the blue thing is a blue sponge. its good. filter feeder. but hard to keep alive. need to feed it alot of microscopic food....not worth the effort if its a hitchhiker.

I see a tank that'll soon be having an algae bloom and a blue sponge that might be dying as it looked like it's turning white. Good Luck. Like what Mansiz said, don't lift the sponge out of the water. air bubbles trapped in it's body will kill it.

Purple up's supposed to build coralline algae, how come your rocks turning green? what other additives you dose? Dose prescribed dosage. Don't over do.

ok here's what happen.

1) Brought a T5 lighting 2 x white , 1 x pink, 1 x blue at jan.

2) There's no green algae at sight using the old 4ft lighting.

3) after installing, i notice the green algae starting to appear (thinking the light is feeding it)

4) 1 month later, the live rock which is brown turns into this colour. (only this liverock). rest is still brown and some purple (seed for purple up to help me blllloooooooooom)

Its nearest to the return pump so i think it might be the cause of the top up water (non di/ro) , using tap water to top up after resting it for 5 days.

At Feb, starting to dose

SeaChem Reef Buffer (to up my ph from 7.9 to currently 8.3) 5ml raising 0.1 to the 4feet tank per day, thats all

Rest is topping up with water.

hmm, thinking of moving the rock to my sump to it from exposing to light <-- does this help?

It seems like your new light fixture is giving the algae the correct light spectrum to grow, especially the pink one. Unless you have a planted tank, you should stick to tubes with higher color temperature.

My rocks was stripped of coralline once when a green algae bloom got to them. I then changed my tubes to 14K. after that coralline slowly recovering. Maybe I'll consider purple up too... ^_^

Water can be another cause. Tap water might have nutrients favourable for algae growth. However, if you've been using tap ever since, then this is not likely the cause.
