oh yeah..just like you can be upside down like a bat with your head on the floor and legs up and yet your food can slowly move along your digestive system coz of the contractions along the way... hehe

not too sure leh... i only know their name and their function and how they work... they work by using rollers to press along the tubing and thus do not have direct contact with the delivered fluid...thus no contamination which is important in health care use ..... and they use generally 4 to 5 w for the basic models...but can deliver up to 10ft head pressure because of the roller-concept lor..hehe

yeah lor..which is why they are expensive you see.... they draw medication from a container and adminster to the patient in fixed dosage you see...very reliable generally.. what i do is put small food like cyclopeeze in a container of water and use it to feed into the tank at a dosage i want lor..hehehe in aquarium...we call it generally as dosing pumps but they are actually peristaltic pumps

or this kind

this is the kind of peristaltic pump that i intend to use to feed my anthias for a more regular basis rather than throwing cubes of food into the water at intervals lor..hehe

Yeah.... Now for the ugly part, I admit, I confess, I am guilty....of growing hair algae in the sump with my other macroalgaes... i used to prune them painstakingly and throw them away coz i like a neat looking refugium with nice macroalgae....but i realise these hair algae really grow damn fast and probably good nutrient absorbers as well....provided they dun take over the main tank....hehehe so....i am happy to say that i am one of the few reefers that consider hair algae not so pesky liao...hehe

yeah..but peristaltic pumps not cheap....unless bros here got lobang..let me know.. those adjustable rate peristaltic pumps costs about 300plus to 400plus i think....or even more

not a few days supply lor... just for the daylight cycle lor...maybe start off with a small amount first...and then adjust accordingly means i prepare food for the 10-12 hours of light in the tank ....... every day prepare lor...at least wun spoil like u say lor.... unless within 10 hours..really deteriorate very bad then maybe i put the peristaltic pump on a timer and time accordingly and feed within a shorter time with less food lor...hehe lots of factors involved here....so can slowly think about it..hehe

yeah..i figured...really... u see ah..the cubes i push out of those trays of hikari mysis shrimps, daphnia, brine shrimps... with the bigger size cubes of MBF food and cyclopeeze.... it is about a whole tray of the hikari frozen food pack or even more liao...and i buy those hikari frozen packs in their styrofoam boxes....not single trays...because they get used up fast...hehe and my family is already complaining the fish food is taking more space in the freezer than our human food liao... sigh..must get a dedicated bar freezer for fish food soon..haha er....i used 6 packets of contraphos since the start of my 6ft tank.... er....6 packets quite alot right? hehehe haven't change yet...but will go get another 6 packets of contraphos soon ....or biophos..hehe but yes...i have hair algae growing in my sump...but due to the way my sump flows..the hair algae did not really migrate to the main tank system in clumps....i use the eheim 1262 return pumps with the sponge also lor...so everytime i go pull the hair algae out before they reach the return pump... last time i keep pulling them out...but then its a lot of hard work..and then it dawned on me that since they are in the sump and not really a nuisance there....i dun mind keeping them there lor....hehe my phosphate levels....not totally 0 lor..hehe pic from the last time i took the pic...

in fact, i think i may be setting up a peristaltic pump system to deliver prepared liquid food from a container with all the hikari stuff, cyclopeeze and watever small food and set the pump to supply food to tank at a few ml per hour.. this will ensure consistent flow of food to the anthias and not in bursts like when me or my maid feed them.... this...will be one of my new projects to the tank

yeah man..talk about feeding..i hope i did not set off an anthias schooling craze unintentionally by the photos.... i feed alot..like AT said...many many many times a day...i can finish almost a WHOLE tray of hikari frozen food /MBF planktonic food/ lots of cyclopeeze within a day if i want.....which is why i went to get the H&S skimmer to work with my AquaC...... and algae is growing madly in my refugium...the main tank is very clean coz of the tangs in there and my scraping of the tank walls... but....if you are not free to feed the anthias almost every hour or every few hours....then you may have problems keeping them in the long run..... even when i am outside...i call my maid regularly from outside to ask her to feed the anthias for me.... i guess this is the important part as AT mentioned and like AT said...a few months for the anthias is not success....maybe pass more than a year timeframe is a good gauge if it is a success

thanks bro deepblue...hehe hope u can see schooling also

remember dun suddenly put too many also..instead of grouping them...the newbies may even scare off the settled ones....add slowly if you find the settled ones are still shy....

this is what happens when a female starts to join in the pack from the front...the bartlett or male queens will get her to go behind very soon....in this case...it is the bartlett that is doing the herding

like this...very interesting phenomenon..and when more join in from the rockworks....the males take turns to usher....

Like what i told bro deepblue, i recently found the anthias forming a hierachy of some form.....the male purple queens and the male bartlett swim in front of the pack...and when the rest of the anthias slowly join the group...the males take turns to *usher* them to the places behind the group....or spaces between the pack.... they really lead by example....and the females seem to be happy swimming behind the males....ooops....guess fishes show sexism also..hehe

yeah..on the website

go read your ev120 manual...and you see those recommended pumps there...especially the iwaki model... u go and find out what is the flow rate of this iwaki model at 6ft pressure and you compare your sicce at 6ft....if the flow rate is the same..then u are ok with the pump...if not, and most probably so, then you should use another pump to match the perfomance of the iwaki pump at 6ft pressure not sure wat is the iwaki model recommended for your ev120..but i think it is iwaki 20RLT

not good to put the name here lor...like commercial post.. but anyway, this is not the only pump can do this at 6ft...just go around any koi farms, fish farms or even LFS that carry pumps and look for the pump's perfomance at 6ft height..... alot are very impressive at zero head....but when it comes to height..most fail miserably

still thinking about how to light my refugium now that i cannot put 4ft T5 tubes...should i put 2 foot T5 tubes or go straight for MH...but i still dun like the heat of the MH...hmm......dilemma what you think guys?

yeah lor..didn't i tell you last night you can tell the perfomance upgrade immediately by the air valve? so much air ###### in....lol...hehe and somemore...no matter how you open the gate valve..the bubbles come so readily without even seeing water level in the foam tower....the days of adjusting the water level is OVER...now is adjusting the bubble level to get dryer or water skimmate..hehe now you are a believer
