hahaha leave them alone, should be fine

Thought I'd add some dimensions and specs for it to aid decision making. From the maufactuer: Specs - 13" tall x 6" wide x 2-3/4" deep - Minimum tank opening 5-1/4" x 1-1/2" - Minimum tank height 7-1/2" - Minimum space behind tank 2-3/4" - Maximum tank lip 1-3/8" wide - Vertical clearance above tank 10-1/2" - Includes Maxi Jet 900 pump - Rated for tanks up to 20 gallons - Includes nylon cleaning brush - EPDM o-ring for collection cup adjustment Features: The Nano Remora is built from translucent gray acrylic to inhibit the growth of algae and marine organisms. The two screws at the base of the skimmer are used to adjust the Remora so that it is level with the back of the tank. The collection cup can be adjusted up or down by moving the position of the EPDM o-ring around the cup. On the maxijet 900: Maxi-Jet 900 PH Powerhead 230gph Item #: 198228 Availability: Usually ships in 2-3 business days.

Hi there, is anyone interested? It's really a good price..

Oh sorry I forgot to add, please PM me, add a reply, or simply sms me at 9336 3135. Thanks for viewing. hope to hear from someone. Cheers

Hi Larry, Yes, a DSLR - Sony Alpha a230 - borrowed from my brother. Shame I can't capture the true aesthetics of the tank and lights though.. its really tough to photograph LEDs. I use a tripod and put my settings to Aperture mode. Cheers,

Hi Everyone, I just purchased a brand new AquaC Nano Remora skimmer with a Maxijet 900(only received it today from Edmund of Fresh&Marine, thanks Bro) for my 3.5 gallon pico - it's way too oversized for my tank - wrong decision in my state of fever. Due to the ill fit for my really small tank (what was i thinking?); I have no choice but to let it go. Its barely half a day old, and everything is in mint condition (see pictures please). Since it's technically second hand, I have no choice but to sell it at a slight loss. I am happy to offer the set at $210 - a $40 loss for making decisions when I am ill. I think this price is very attractive and reasonable; I also offer a brand new Dazs external filter (small), again barely few hours old, for free with whoever buys the set. That is a total savings of $60 for nothing at all. Everything comes with all fittings I'll be really grateful if bros and sis's can help. Collection can be at any MRT station this entire week, but only evenings after work hours or the weekends whole day. If you live in the north, I'll be happy to meet tonight or tomo (but no guarantee cos I'm still ill). Please let me know. Cheers Overview of set: Closeup of skimmer. Note the mint condition (White specs are dust): Close-up of the parts and fittings. Again, note the mint condition The free DAZs external filter: Close-up of parts:

I must have been extremely feverish (am down with severe viral flu) when I typed this "the PAR38 and incessant water changes (small volumes) is slowly bringing nitrates down again.." Despite being an open minded scientist, never would I make such wild conjectures as PAR38's bringing nitrates down, unless one extrapolates hyperbolically . Apologies folks. Actually meant that the continuous water changes brought Nitrates down.. The point about PAR38 was in relation to colouring up of some of my browned out corals - i somehow mixed the two up in my feverish state. Cheers

Thanks for the encouragement Junkai. Will do once some of my corals that have browned out regain their colours.. Despite my very very supportive mother who helped with the maintainance, the water quality declined during my official travels hence the loss of colours.. the PAR38 and incessant water changes (small volumes) is slowly bringing nitrates down again.. Some of the corals are responding v well to the PAR38.. Even the softies are "licking" the bright lights up..Am thinking of posting a series of colour changes to the corals.. but that will take some time capturing the pre and post pics as they change

Hi Junkai maintaining such a small system is v challenging but the rewards are proportionally fulfilling.. Aquascaping and attaching frags can be a real test of dexterity; trains you to have a surgeon's patience and skill This system is 6 months old by the way.. I stocked it slow and steady with frags from many good reefer friends.. Like it? Maybe i should start a thread on it...

Yes,.. they spread like a virus.. just gotta have them

Hahaha Bro 91Litres, glad you like it. Please dun say all your money i gave you a v v good discount cos you are a student (psst, between us only k?). Keep on reefing! We need young blood like you! Read more, learn more and do more. Cheers

Also, Bro 91Litres, thanks for your support, hope you enjoy using the PAR38. Let me know how you find it. Cheers!

Hi StewP , it's 21 cm above the lip of the tank, 30cm above the tallest Acro frag.. all my corals are frags.. Thanks for the compliments, but the pics do not do it justice. Cheers

Hi everyone, as promised, here are some pics of my PAR38 CREE LED Spotlight installed over my 3.5 gallon pico. People who have tried photographing LED setups know how difficult it is to capture the true brilliance of it, so please forgive my much-to-be improved pictures. For now, I'll let pics do the talking, commentary to follow Hope you will enjoy these pictures that were taken at night. Please note that the camera does not capture the full intensity of the lights - our eyes perceive the colours far better! Overview: Full tank Shot: Scale of my tank (note the size of the Coca Cola can): Another with the PAR 38 : Coming up.. pics of the specimens...

Thats a v nice fixture too Bro Jun even sexier than the Tertial from IKEA. Will be happy to hear your comments on the PAR38 and its realistic shimmer effects anytime. Cheers!

Bro PooMoon (Jun), If you are reading this, thank you so much for your great support, its a pleasure knowing you. Hope your ankle heals soon. Do post pics of your PAR38 setup soon so we can bask in its glory. If you don't mind, you can even discuss it in this thread. Happy reefing and spotlighting. Cheers!

I can understand Jun Kai The springs add some suspension and stability to the fixture. Mine seems very steady. Keep in touch. Cheers

Hi Bro FuEL, Welcome to the PAR38 Club. I see you bit the bullet and bought the IKEA Tertial fixtures too Cheers Bro

Hi everyone, It seems I have forgotten to mention the fixture model in my haste, apologies, my bad. The fixture from IKEA is Tertial. Hope this makes it easier for bros and sistas to find it. Cheers and good night.

Hi Bro Joe P, saw your other post seeking advice on the efficiency of LEDs for SPS dominated setups too. I am certain that through the course of your exploration and research on LEDs, you would have come across anecdotal evidence on the efficiency of high-powered LEDs - Bro Sherman's pics and threads and others who have tested LEDs in this and other forums (check out Nanoreefs especially) provide some testament to their effectiveness. What the PAR38 provides over other normal fixture-type LED lights is the ability to harness five of the LEDs into a very focused beam of light- though the spread can be adjusted by the height- in effect, fulfilling the function of MHs, minus the costs and heat. PAR measurements of this PAR38 LED spotlight, using Apogee quantum meters, have also indicated that the spotlights generate approximately 220 PAR from as high as 20â€, 425 PAR from 18†(through air), and roughly 130 PAR at the sand bed, based on 16†depth ( in water). Of course, empirical studies comparing LEDs and MHs by Sanjay Joshi, if and when out, would likely add further credibility to the advent of LEDs as the future of aquaria lighting. Bro Joe P, I welcome you, and others who are interested but need further assurance, to come over to my place to see the lights for yourselves before deciding. Except that we will need to set a common date, if you are interested. Hope this helps. Let me know? Cheers

Hi Bro Terryz, yes and yes. But IMHO, it also depends on the angle you use the spotlight. Let us not forget refraction. Angling the light and placing it straight over the tank will result in different PAR values. Even if the PAR is more than sufficient for the light requirements of light loving corals, ultimately, it may just mean that you need to turn your lights on for shorter periods. Of course to be safe, it is best to maintain roughly a 10" distance. But please do not use these lights in an enclosed hood. The built-in high fin density heat sink is more than sufficient to handle the heat without a fan source but it cannot be enclosed. If you already have lights over your tank, these lights could either be additional supplements for trophy specimens, or as a main source (depending again on your reef config). Hope that helps. Bro Sherman, thanks for the input too.

Bro jkit, sure, will post a better pi when i am back. am out now, but Bro Poomoon was right about me just "probing" it into the tank from the top. It works well at maintaining my 3.5 gallon at 27 deg through the day, with a 1 degree drop in the night. No ill efects on my tank inhabitants though. Chilling effects will be enhanced if you plumb it into the system with insulation. Cheers

Bro Poomoon, U have a msg

Bro Terryz, and other bros who may have the same questions will be happy to advice if you can share some infor on your reef layout, tank dimensions and the light requirements of your tank inhabitants With that information,I can provide better advice For example, if your reef layout is concentrated in one area roughly about 12", with lower light requirements around the edge, you could just use one if you already have diffuse lights around (eg. flourescents). Thre spotlit effects will also be dramatic. However, if your reef layout is rather spreadout, then you may need two. It also depends on what your reef inhabitants are. cheers

Hi Bros, sorry i may have given the wrong impression but the nice clean tank in the pic belonging to Marcello was not lit by the PAR38s but by Japanese Supakaru spotlights. However, the PAR38s were made to produce exactly the same effects. And yes, a larger tank will require more of these units. Depending on the vertical height, one PAR38 with 40 deg optics would get u close to 12" horizontal spread. What are your tank dimensions and coral layout? Perhaps I could help?
