yeah...nice piece.... i am sure my relatives will bug me when they see it today... it's bwilly's now another free gift from one reefer to another

yo... hope u like the tiny bubble... here's the small one...if you want it, can u please call me at my hp before evening my relatives come if you want this piece? so that i can tell them it's not mine already.. bro deepblue is very right...the big one is nice....probably keeping it... i thought they were very dull and brown in the centre...end up at home under 10KK lights, the centre is like *blueblack* purple.... give me a call if you want it

he told me the time... deepblue u picking jie right? i think most prob i still sleeping... enjoy yourselves..the rest of the island nothing much it seems

hehe..stock market ah...more like futures exchange liao... but the red lobo as i said..only the outline is red..somehow the colour of the center flesh not as appealing as your allreds lobo hor...

actually there was one that looks almost like a perfect 8....near to this piece you have...which is almost an 8shape also ..almost wanted to get but held back..hehe

quite alright also..but also kinda disappointed...tot he will fight with voldermott again...ooops...he shall not be named anyway..the next goblet of fire should be much better...hehe actually my skill not good lah..if not i work in advertising firm liao just take some creativity to think of how to match stuff we have in our tanks to movie posters

wah liew bro...you should paste the red lip on hermione's lips lah..harry potter dun put lipstick one.. see my this one.... i can use my gorgonians to invoke... EXPECTO PATRONUS!

i already said...the pumps flow can be found at the RC's website.. the aquaC website only gives u list of recommended pumps... u need to use aquaC list to go RC calculator to get the flow rate at height loss to know what is the flow really driving the skimmer.. at different heights...different elbows...different conditions....u will get different flows...from the RC calculator i did your homework for you

hamann: these are the pumps recommended for your ev180 in your manual besides the pumps are the flowrates for them at 6ft...so now u can know what rates u should be going for when u buy your new pumps • Sen 700 453 GPH • Mag 700 340 GPH • Rio 3100 353 GPH • Dolphin DP-800 (valve recommended) 491 GPH • Iwaki 20 RLT 334 GPH • Little Giant 3 MDQ 547 GPH they are in gallons per hour..just convert them to litres/hr by multiplying about 3.8 to the numbers as you can see..even their so called recommended list range from 334gph to 547gph at 6ft height flow..and like weileong say...you have to use more powerfu pump here as they are running on 60hz compared to our 50hz power supply... paiseh weileong....talk about ev in your thread when it has become history already

i am rushing off now... u need to do some homework to get the flow rates for your recommmend pump list at 6ft height...reefcentral has this calculator for u to choose the list of pumps and find out the flow rate after some variables... if u still dunno...at night when i am home then i calculate for u...but it's best you go figure it out yourself...it's part of the fun of reefing...

there is a moving variable going on.... because even if they are using the same injector, the size of ev240 and ev180 differs....in terms of mixing box as well as foam tower diameter and height.... for ev240....the injector they say simulate 6ft of pressure loss....so if they recommend their list of pumps....we have to look at the water flow from their recommended list of pumps at their 6ft height ratings...which turns out to be around high 2000s to 3000s litre/hr of flow for ev240 for 180....even if the injector is the same...and simulate 6ft of pressure loss....you go check the recommended pump list flow rate at 6ft...probably only 1000plus to 2000plus litres/hr at 6ft to run ev180...any higher and u will flood the whole skimmer... just like if i use a pump that at 6ft height can pump out 5000litres/hr..i am going to flood my ev240 which seems to be recommended to flow out at 2000plus-3000odd litres/hr at 6ft based on their recommended pump list.... so even for the same injector...the same flow restriction of the injector that simulates a 6ft height loss of flow...the skimmer sizes are different and thus the flow at 6ft to run ev180 and ev240 will be different... i think the best flow rate to run my ev240 is in the 3000litres/hr region (at 6ft) any lower, the foam will not climb up easily..any higher the foam will overflow the cup..which is why when weileong runs a md55...the effective flow rate at 6ft is probably well over 3000litres/hr and he needs to tee off to reduce the flow rate... so for your ev180, i think it should be 1000plus to 2000plus litres/hr region (at 6ft)....u go check all their recommended pump list for your skimmer and get their equivalent outputs at 6ft..then u will know the range where they actually want you to run the skimmer and then u get a pump that can put out the highest water flow at this range after considering the height loss

i think i mentioned somewhere...u need a pump to simulate the pressure lost by the injector head..... for my ev240...it simualtes a pressure loss of about 6ft...it's in the manual... assuming your injector is the same as mine, means your ev180 injector also simulates 6ft pressure loss... go look at your rio3100...how much water really flows out at a height of 6ft... and then you get another pump that can put out more water at 6ft than your current rio3100 eg....i am using a 6000litre/hr pump for my ev240...but this pump at 6ft high only pushes out 3000plus litres/hr.....so if i find that the foam is not enough..i need to get a pump that pushes out more than 3000plus litres/hr at 6ft to get more foam so assuming that your rio3100 pushing out X litres/hr at 6ft height, then u gotta get a pump that pushes out X+Y litres/hr at 6ft height... but u go see your manual and see what height is your injector simulating a pressure rated pump may be just rated at 5000litres/hr at zero head..but let's say if it can still push out 4000litres/hr at 6ft height, this means this pump will be better than my 6000 litres/hr non pressure rated pump that can only push 3000plus litres/hr at the same 6ft height.. so dun be looking at the face value of the pump flow at zero height...go look for the flow at 6ft if your injector is the same as mine...

use a stronger pump hamann.. i feel that their recommended pumps are a tad too weak.. if u use a pump significantly more powerful than rio3100, there will be a significant increase in foam... i am using ev240...i know their list of recommended pumps. weileong also used their recommended pumps with not satisfactory results...end up use md55 and tee off the power...coz if you use md55...the foam just floods the cup so for us ev240 users...we gotta use a pump between their recommended list and md55's power to get just the right amount of foam that the skimmer was designed for.. too weak a pump and the foam finds it hard to climb up

and the problem would be spotting them amongst those bubbles...

wait scarly the LS all hyperventilate in the highly oxygenated water in the skimmer

ok man... this saturday or sunday lor...we see how... keep in touch by sms maybe you come up my place take if you pass by lor... u know me...i dun like to go lfs on weekends

next week if you got time, remember to get your complimentary small bubble from me...hehe today good harvest hor..

the 2 suncorals one very long ago liao...almost a year or so have liao...not sure the 3 nemo tshirts came with 3 buckets as i bought for my 4ft tank last year...and then also use for my current 6ft tank set up lor..hehe now no salt liao..have to go buy soon..hope they have new designs

hehe..jie... wah liew..u want your boy and weileong's gal wear 情侣装 ah seriously the other 2 of the nemos worn until very jialat liao..including the suncorals..somehow don't look old in pic....only the center nemo one is slightly newer... i warn u already hor...i might have OVERSTRETCHED the tshirt...LOL

jie: dedicated to your sun coral fetish

jie...i suspect the center one of the nemo i havent wear yet...but somehow i keep too long...doesnt look new already...or maybe i worn once or twice...hehe

ok lah...i go off liao..have fun and enjoy yourselves at dinner

wah liew....bo jio....lol.. sometime next week we go out have lunch together lor... weekday afternoon lor....

poisonous one ah..aiyo..then next time dun eat liao..hehe today cannot....packed schedule all the way till friday...saturday onwards slightly more free....slightly only...
