Why would UV affect copper treatment?

Hi anyone knows where to buy or who has frag to let go?

Using bacteria to combat algae can be done. But it's a very slow process. Like taking Chinese medicine. Sometimes, you can overdose, and end up with more algae before things get better. Meanwhile, some corals may perish. Best method is still to manually remove and make large water change. And also black out tank for 2-3 days, and switch lights back for 30mins per day for 3 days and then increase by 30mins every 3 days until u hit 8-hour photoperiod. Go extra-light on feeding. Use carbon and GFO. During this period, u can load up on light-hungry corals. But not fish. Introduce a sea hare. For slime algae, Chemiclean is the miracle cure. It works like a charm, and it does not harm even the most sensitive coral or nitrifying bacteria.

What temperature do u set your tank at? Anything lower than 26 will bound to cause constant condensation.

I see But I never had this problem with previous tank (using Hanna too).

Nice colours on yr SPS dude! Could the brown stuff be slime from chemical warfare between corals?

Hanna supposed to be the gold standard. Anyway will monitor tank inhabitants. So far, SPS showing no stress. I also suspect the salt. Switched to FM for this new tank. Previously using Red Sea Pro, and I didn't encounter such fluctuations at all (with same Hanna kit).

I use Hanna test kit. Ca reactor: I always thought the reactor will raise kH and Ca in proportionate measure.

The calcium reading in my 3mth old 6footer is crazy. Using Tunze Ca reactor. At first, 290. Then I added Ca manually. Testing before and after every dose. Then somehow it shot up to 600 when I switched to a new batch of powder regent (previous one ran out). So I suspected it was the old regent. I let the Ca self-correct by using Red Sea Pro salt (which is super high in alk). Last week, things began looking "normal" - alk 10.4 and Ca 429. Then today, haywire again. Alk 10.0 and Ca 529. Anyone knows what's happening??

Sold!

Palm size flat rock fully encrusted. Long tentacle and very luminous. Clowns love it. $30. Collection Upper Serangoon.

Hi light purplish acro (on the right of mother colony behind purple valida) + forest fire digi (behind milli) avail for swop. U got anything interesting to offer?

The soda lime system prevents excess CO2 from getting INTO the tank but does not remove CO2 that has already built up in the water.

How's the soda lime system working? I simply put an air pump on timer to blow off excess CO2 in the sump at night.

Tnx

Hi is anyone using an ozonizer? Used to be popular but seems quite uncommon now. Care to share your experience?

Plumb directly with your existing power head. Hose size: smaller better because less work for power head

$70, negotiable.

$88 Cash and carry Upper serangoon

Anyone has a frag of above to spare? Pse PM...

What happened to the Moorish Idol?

Mystery deepens!! I raised calcium with powder. Thought that was that. But lo and behold, it kept rising. Now at 600!! Cedric, cannot be reactor tuning. Because kH was ok. Possibikities: 1) FM salt batch has low Ca. 2) Hanna regent gone bad (spike happened when I opened new powder regent). 3) Both of above. Anyone has other theories? This is perplexing because before this episode, my kH and Ca always moved in tandem - never separately.

Yeah. Trying a copperband though ... Wish me luck!

Thanks! Yes I recall seeing in your tank. Someone at Advanced Aquarist said he kept one for 10 years without incident. Anyway I decided against buying one.

Hi has anyone kept regal in mixed reef? Can plse share your experience on how reef safe it is, and how long you've kept it?
