Flakey Flakey, not centropyge though

The whole lump of them would have trapped decaying matter, if you want...u can always rinse them regularly with tank water during water change and put them back to retain the beneficial bacteria...maybe u can put them in a plastic tray with holes so that its easier to lift them up for a rinse now and then to dislodge the particles trapped within them. but many will advise you to get rid of it once and for all.

well...many factors can be involved....why don't you solve the nitrate problem first and eliminate one factor out of the equation. and instead of tackling the nitrate problem at the end result, why don't you solve the problem at the root of it, before organics turn into nitrates.....reduce your organics level in the water column by less feeding/less stocking/better skimmer and so on.....and the eventual results will be less nitrates... and you got one less equipment (denitrator) to meddle with and one less equipment for Mr Murphy to visit.

u may need to reduce your nitrates further by a better skimmer or other means... 20ppm nitrates may have been a stress trigger for your clam.

u may want to check your 20ppm nitrates...what skimmer are you using now btw?

i think it's a balance of the foam thoroughput and the diameter of the riser decided by the manufacturer, when he knows the kind of foam his skimmer will render.... the surface tension also plays a part when the foam rises to the top edge and when the matt spills over, it pulls along the next layer and so on... the thin layer that you observe is like thin layer slowly *floating* up instead of being pushed up by a thick cushion of foam underneath it right? hehe..yeah...quite interesting... like the premature bursting of bubbles u have mentioned besides the thick matt of foam that eventually spills over in the collection cup...even if we assume the burst results in spitting of the organics in multi directions...it will probably land directly overhead underneath the cap, the sides of the cup that often prevents us from seeing into the cup clearly, or even spits itself back into the thick cushion of foam underneath it that is ascending the riser....so it may not be such a big problem... personal opinion lah....hehe but anyway hor...we abit off-topic liao lah..this thread is about manufacturers ratings

wow....1m tall now for the bk300... now we are talking seriously i felt the super high air/flow of the RD is actually quite disruptive in the relatively short chamber considering the prowess of the pump...but when the new batch of 1m tall bbk300 comes in....one will definitely notice that the added height will tame down the bubble dynamics. i actually suggested to a friend to chop off the existing short chamber and add a middle extension to increase the height, but definitely will affect resale value. But now that RE is actually doing the increase chamber height (hope not bundled with increase price ), it's definitely good news for new buyers talking about riser tube...definitely small or big a reduction will have an effect....but i haven't experimented with too many sizes myself. maybe those who DIY skimmers in bulk may have tried with different riser diameter sizes and can contribute to this aspect. from what i notice, if the foam is not massive and "powerful" enough, it will have a hard time ascending a wide riser.....i think maxima has mentioned before.....small riser necks are to aid the climb of foam for underpowered skimmers that need the pressure difference to push the foam out into the collection cup....but actually all skimmers need this slight change of diameter to aid the foam push, only a matter of how much.... but to address your question...i think if the skimmer's foam is not ommph enough, a wide riser neck will result in a tough time for the foam to rise and may result in very dry skimmate and very dirty inner necks....but then to raise the water level and thus raise the foam probably can get past this... on the other hand if the riser neck is too narrow, the foam will be pushed out very fast and skimmate will be rather wet generally unless the user deliberately lower the water/foam level and get dryer skimmate... but there are some skimmers whereby somehow the user die die cannot tune the range of skimmate from wet to dry and is limited to either wet or dry skimmate... well...just my observation so far ps: but anyway we can think of the riser tube like an exhaust pipe....if the engine exhaust(foam) is alot and powerful...need a bigger pipe so that it doesn't bottleneck the system.

actually i find that if they have to throttle back the pump, it is really such a waste. I wonder why they rather handicap the RD instead of using bigger/taller chambers to accomodate the high air/water flow...but probably that would mean even higher prices

tat's why i always say....manufacturers guides are just a rough starting point.... if u buy a skimmer and its published capacity is already many times more than your water volume and YET you still have residual nitrate problems and other problems....it just means that you need to move on to a better one. (unless you are happy with the high nutrient levels and want to keep it that way) I am glad this new owner of AP702 has learnt that his previous GERMAN skimmer cannot handle his application context and decided to change for a better skimmer in the AP702, instead of applying blind faith and stick to his previous skimmer (and its ratings). If the AP702 still cannot solve his issues, simple, it doesn't mean AP702 is a bad skimmer. It just means it is not good ENOUGH for his application context.

they will always tell u....add dwarf angels with caution.... tangs are generally reef safe right? but u see some tangs hammering corals also so do everything at your own risk....weigh your consequences

sad to see another reefer giving up upz for your sale

wah so cute! best wishes from a senior AT

ya, they have a wide range of pvc stuff...here's my slotted VDL... your slotted pipe cutting angles not very neat....in fact, mine is not neat also if u look closely

weisoon, have u noticed the slots made by VDL not very uniformed? i think we DIYers can make neater slot-cuts on the pipes than what VDL did, their cutting angles abit off sometimes...lol.. ya, singapore cannot get VDL parts, have to ship in from overseas...but never mind lah....GF and VDL same dXX standards, so not too difficult to use GF parts instead of VDL lah....although GF parts are getting more and more expensive

actually not say many also lah....if you wanna do a poll with every singaporean skimmer users, deltec is still lacking alot in numbers, even when compared to H&S because you should know how long sealife has been around. now that edmund is officially bringing in deltec, the number of deltec users will grow but definitely still a small minority, even taking into account those who got their deltecs by their own channels.

easy lah...alfa put his name on weisoon's waiting list...and weileong put his name on my list anyway, i know 2 more 1004 users around in singapore....may not be in this forum though

dun off topic again lah... weileong...take some pics of your piping so that riot have a better idea of what to get..

shhhhhhhh anyway if weisoon needs d50 parts i may still have....have to ransack my store though. but i believe weisoon is always well equipped

the hose adaptor on your H&S is d16 i believe, thats why the 16/22 eheim hose with an inner diameter of 16mm can mate to the H&S d16 easily. but no problem here if u dun mind some untidiness: get your 16/22 hose to mate to a short 19/27 hose - means u squeeze the 22mm outer diameter into the 19mm inner diameter,secure the joint with clip or glue and then squeeze the 19/27 hose into the 25/34 hose - means squeeze the 27mm outer diameter into the 25mm innner diameter, secure the joint with clip or glue and there u go....u solved the inlet problem means u have the 16/22 joining a 19/27 which joins the 25/34 which eventually mate with the d25 pipe/hose adaptor that will feed your skimmer. or u get proper pvc reducer fittings will look much neater as for your return of d32mm piping, i got none to spare you because after using some for my quattro and some for the 1004, nothing left, but maybe got some elbows and misc fittings if u want to buy u can PM me. but u are lucky, the normal hardware shop so-called 25mm size is a close fit for the d32 size standard The rest, are misfits so remember go hardwareshops dun buy 32mm for your d32.....

d32 size piping bro...not d35 if u just need a short d25, i can pass a couple of inches to you...just connect a hose with inner diameter of 25mm (eheim 25/34 or hardware shop hose) and hoseclip it and you are on your way to feeding your skimmer...you can bypass the d25 hose adaptor.

never seen a batmobile going for fuel topups before..probably needs aviation fuel anyway, what's the next ride on your mind alfa? the spider?

alfa, check out your ride with new decals http://www.sgreefclub.com/forum/index.php?...pic=29173&st=0& DELTEC ROCKS

check out our alfa's ride just kidding

alfa, you should ask deltec to make car decals for you to paste on your alfa romeo "DELTEC ROCKS" or a bumper sticker "KING OF ROCK AIN'T ELVIS, IT'S ME, COS I HAVE DELTEC AND IT ROCKS "

nice bro.... i got one colony from our generous dispar as well, beside is the colony from weileong. at their rear is the ML lobo that i bought over from you that time bro
