Judging from the response, pity no one else here seems to think so too.

http://www.seaslugforum.net/factsheet.cfm?base=glauatla Anyone has it in their tanks? Glaucus atlanticus Forster, 1777 Order: NUDIBRANCHIA Suborder: AEOLIDINA Family: Glaucidae DISTRIBUTION Circumglobal in temperate and tropical waters. Glaucus atlanticus and its close relative, Glaucilla marginata, live in close association with what Sir Alistair Hardy described many years ago as "The Blue Fleet" - the siphonophores such as Physalia, Velella, Porpita and the other associated animals including the "Violet snails" of the genus Janthina. All these animals float on the surface of the ocean being carried by the currents and the winds. Most of us are only aware of their existence when days of onshore winds blow great fleets of them on to the beaches, causing pain and angst for swimmers. Both species spend their life floating upside down in the water, partially bouyed by a gas bubble in their stomachs. The two nudibranchs feed almost exclusively on Physalia, and as Tom Thompson and Isobel Bennett reported some years ago, it appears that they are able to select the most venomous of Physalia's stinging nematocysts for their own use. Like most aeolids, they store the nematocysts in special sacs (cnidosacs) at the tip of their cerata . There are a number of reports in Australia of kids engaged in "Bluebottle" fights - where they throw stranded Physalia at each other - being badly stung by inadvertently playing with Glaucus and Glaucilla, both of which, by concentrating the most venomous of Physalia's nematocysts, are much more deadly. Another interesting feature of the two species is their colouration. They both exhibit a textbook example of colour countershading. Their foot and undersides of the cerata, (which because they float upside down is effectively their dorsal surface), is blue or blue and white which helps to camouflage them from predation (sea birds) from above. Their true dorsal surface, which faces down in the water, is silvery grey to effectively camouflage them from fish looking up from below.

Some of you may have seen this ad/survey/whatever for houseboats haunting SG forums and property websites. http://www.clamn.com , http://forums.hardwarezone.com.sg/showthread.php?t=2064317 , etc, just google houseboat clamn. Wanna ask the people here if they've any experience in living on a houseboat. I dun mean living on a normal boat used for rudimentary/temporary accomodation as part of a diving expedition, but a boat specially made for living in, berthed at a peaceful marina at night, out wandering Pulau Hantu/etc during the day on weekends. No doubt there will be inconveniences in regular maintenance, some possibly quite major annual operations, and costs will not be cheap, at least few hundred even after assuming some of the biggest costs can be waived. But I think I would be willing to suffer the inconvenience and $$ if the lifestyle I am imagining is really that nice. Anyone care to enlighten me if it will be terrible living on a houseboat?

Am keeping fresh water shrimp, not coral. But now lacking a nice big base container, needs to be a shallow 4x2, but very hard to find, grrrrrrrr!

Ok, I just bought a cl280 instead. So far I'm pretty impressed with it. The workmanship is good, the parts seem sturdy, the manual is detailed and well written, and its very quiet! I would compare it to the sound of the typical 3-speed wall mounted fan at the lowest speed. And the sound when it kicked in and out is a just a slightly audible click. I tried it out on just 8 litres of water using a 1200L/H pump. It didn't seem to be working at first despite its fans running, then the temperature slowly dropped from 28.5 to 21 degrees in about 16 minutes. The final 2 degrees took about 5 minutes to cool, followed by a break of about 10 minutes before the chiller kicked in again If I scale everything up, then I estimate cooling 160L from 31 to 23 degrees would take about 6-7 hours. To maintain betweeb 23-24 would take maybe 90min of cooling and 200 mins resting. This is a slightly more optimistic calculation than the graph in the manaul which suggested >120mins of cooling required.

Ok, thanks for all your help, I'll probably be settling for a cl450, will be going down to Jireh later to chk it out. They never replied my pm asking for resun prices, maybe they thought I would never buy

Based to your experiences, now I'm seriously tempted to get cl280 rather than cl450. Now my final question, how often does it kick in and how long does it run each time?

Hi, that was very helpful, may I know what are your temperature settings and the temperature without the chiller? Your tank volume is about 120L right? What's the total watts of heat being used. And how often does the CL280 kick in and out? I've calculated my setup to need about 0.09HP from the jbj website. Not sure how reliable it is for resun....... but thinking I may need a CL450. On the other hand, if cl280 takes a long time to cool my tank down, then the kick in/out noise is lesser also.......

I will be boxing my chiller up, so should be manageable for me too. BTW, you're not partially deaf are you?

Hi Ervine, you've given me new hope! Is the sound of the chiller kicking in and out loud? And do you keep your new cl450 in the cabinet?

Thanks for the feedback, actually I'm planning to keep crystal red shrimp. Planning to do insulation to help reduce the king in and out. Currently reading up on how to soundproof a box to hold the chiller, thought of a design already involving rock wool stuffed between double layers of lead and one long intake pipe channeling cool air from the window in addition to the exhaust pipe leading out of the window. Of course, the intake pipe will need to hold pipes and wires as well, so need to be quite broad.

I will be grateful for some feedback on chillers. Is anyone putting their chillers in the bedroom? How you cope with the noise and heat if so? For me, I plan to vent the exhaust out through the window. So now I need to ask if the Resun models are quiet enough(especially the kicking in and out noise) for the bedroom, taking into account the chiller will likely be placed on a table at about window height level. Also need to know if the resun CL280 can cool about 185 liters of water to about 23-24 degrees. Its a freshwater tank, so relatively low wattage, and I will be doing some, insulating. Yes, I've gone to the resun homepage already, but I feel such specs are never a definite indication of real world performance. Much obliged for any help provided.

granted, but it turns out you know the ultimate answer is "42, but you dun know the question that will make you understand it. I could read Harry Potter 6 now and it will be even better than all the 1st 5.
