Surface agitation = more gas exchanges at the surface = more oxygen. Your PH drops in the night because Oxygen level is lower. This is why some people reverse the lighting timing for their refugiums / switch on the skimmer only at night so that there will be more oxygen in the tank to compensate for the lower PH at night. Hope i remembered these correctly. lol I am exactly that type that will come back from Paris without any of those branded stuff. wahahahaha....

Guys I think you have to be realistic with the price of the product. Was in a class whole day today so brain already half dead. The below is my thoughts and I am not speaking for Maxspect. Just sharing my thoughts. Honestly I have no idea how this thing performs and who knows, 3 months down the road, i might be cursing and swearing at them and my Giesemann will be reinstated. the top notch LEDs lights are prob AI and LA The AI cost approx US 700 for 1 module. (12 inch), If you are to include shipping, then that would be be easily >SGD 1300 + taxes. Likewise the LA cost >$1300 for a 2 feet module. Of course then they come with additional features like dimming and programing. Another viable option is to DIY your own with Sherman's help. He is using 3W SSC LEDs that provides approx 250lm per LED - same LEDs that AI uses, I think. (not sure if this is true for the facelifted new AI model) The Maxspect is a cheaper alternative to the above. With cheaper pricing, expectations should also be set lower. Food for thoughts: 1) PAR : These LEDs are only approx 160 lm per LED at max. What is your current PAR readings from your tank using T5/ MH? Will the PAR reading increase with this new light or will it decrease? So are you seeking to replace your current lightset with something that will provide similar/slight improvement PAR readings, reduce the heat directed into the tank and save some electrical bills OR are you trying to get an LED lightset to substantially increase the amount of light for your tank with the additional benefits of reduce heat and electrical savings. I have done a simple test with the PAR value and the reading is comparable with my 150W MH. Of course 6 months down the road, the a similar comparison should yield a different resultas the MH bulb ages. 2) Spectrum - whether they call it Royal blue or blue or whatever, as long as the wavelength is at 450 - 460, it should be ok right? 3) the 30W LED - inefficient - yes. but at the same time it does provide that boosted 2000 lm per LED which is equivalent to 8 SSC LEDs? So sacrificing efficiency to achieve higher PAR - issit a masterstroke or a silly move? quite subjective. 4) This one I agree. Are they overdriving the LEDs to achieve higher PAR? If it is true, then it does not make sense as replacement of the 36 LEDs on a 110W module will be maddness after 1.5 - 2 years. 5) cost of the light. These are at almost 60% cheaper than the AI / LA. You cannot get a BMW with a toyota car budget. I am nooby lah so feel free to comment if I am wrong on any of my views. Afterall, this is what the forum is for - exchange of ideas and sharing cheers!

read a few user reviews, seems like it does cut back the flow.

jialat... prepared the milk, it was a bit warm, then I just lie on the bed beside baby to wait for it to be cooled, closed my eyes and when I reopen them, it is already 2 hrs later....... too tired ......and my baby missed 1 feed. dang..... wow very nice..... I think Comy is right.... Life is a bit haywire for me now. Don't think I have time for feeding corals. I might even give Suns a pass since they need meaty food. The most I can do is dump 5 in 1 into the tank.

Told you I am a reef nooby. What are those? I need to check the web But 1st, let me go feed my baby 1st.

Wrong lah. i think their 3W LED is only at 160 lm per LED, not per W

just make sure you get pellet feeding ones.

definitely not.

true too. I dun recognize a gem when I see one anyway. Well, the trip is for the ladies in my home. Wife for shopping and Mickey mouse for my girl. doubt there will be leftover time for myself.

upzz

'then definitely cannot install on my return coz I am using using the reefpack pump to drive the water to the chiller (not using a separate pump). Guess the other thing I can do is to try to raise the return tube higher, closer to the surface of the water.

Hmm for a moment, I thought I was in the wrong forum..... later my wife thinks that I am surfing adult forum ....

Is that the Helfrichi's firefish??

Yeah the LED looks cool and thank you very much for the compliment.

ummm i think bid ended already... lol matt got it I think

Yah agree. the start up cost is quite high. Did you see my tank thread today. Tested the Maxspect LED light. One of the cheaper 3w LED in the market. I think it is still not as powerful as the US Crees LED or the SSC 's that Sherman uses but should be good enough for LPS not sure about SPS though. The PAR readings is equivalent to my 150W MH (20k bulb) Just sharing.

lets hope he starts eating soon. Gd Luck!

Looks very bright... hmmm maybe will get one for my nano. My baby sure will be enthused by its colour.

bid $63

Ever considered LEDs?

Cool. I am staying at Mongkok for 1 night. hopefully manage to squeeze out some time. I remembered going there like 10 or 15 yrs ago. So many shops in a row. awesome. How you wish Singapore LFS are like that. Centralised in city area

Hi Marco My wife will definitely scream at me if I take time to go and view your friend's tank after travelling all the way to HKG. Thanks for the offer though. cheers

AWESOME....

oh ok. did not know this trick.
