skimmer pumping rate? anyway, 2012 is for tank size 100 gallons, pump capacity 400gallons per hour to be used...according to the box... but my tank is only 30 gallons at most and my pump is pushing much more than the recommended pump pressure... bought at w@ter cir@le

i mentioned 2012...meaning..weipro

but magnet only will attract iron fillings or small pieces right? copper will not get attracted by the magnet right?

weipro should be overdriven instead of the recommended pump pressure i feel..i am using extrema on my 2012 and i am quite happy with the foam leh... here's a pic today taken:

all not compatible with each other....

new clams at PR? anyone there already?

yeah...even 2 feet tank needs high light coz of the stuff you would choose to keep...me heard many horror stories about anemones especially in small tanks like 2 feet....but i grew to love clams...thus i changed my light to at 150W MH.... otherwise just stay away from light loving creatures lor..hehe

can check out the SPS forum to see the SPS pics

well...i recommend u getting a good pump to drive it...should be worth it....underpowered pump... u will notice by the lack of dense microbubbles in the rising chamber....

how much for the mega ah...if wanna bring in from overseas?

Should be bristleworms

Normally coz they wanna keep Clams or SPS... otherwise..you should do fine with PLs still

Seems like the highest model here is only Extrema... I do not see any Suprema, Mega or Mega Plus around here...anyone has?

jeffrey... how come your pics look abit distorted ah...like the picture genna stretched or something...hehe

clams yes..but sps...they might survive..but u will lose all the vibrant colours...left with brown acros.... normally people would suggest 1 mh for every 2 foot of tank...yours is 3 foot...so u just place those less light demanding corals at the 2 ends of the tank and the light demanding ones like clams directly under the mh lor...

experts also cant assist u if u never state your tank dimensions.

your 8 inch sandbed will not be effective...the sand grain size is too big.....u need those sugarfine size 0 sand for it to work...and even if it does...results do not kick in fast....many many months before nitrate reduction takes place on merit of the DSB....

quite erm erm.....

yeah lor..where got different versions for extrema... oh..i get it...got got..2 different versions... 110V-120V and 220V-240V version ....heeeeee

hmm...at first the standpipe was 30mm...means its inner diameter where water flows is around (30-2-2) 26mm...then it went thru the reducer.....(25-2-2) 21mm...and then it finally opens out to the bulkhead at full 25mm diameter unimpeded... so the water actually flowed from a 26mm hole to a 21mm hole and then emptied into the 25mm bulkhead hole...hehehe

extract from Mr Durso: A frequently asked question is how much water will the Durso Standpipe process? The presence of a standpipe really makes no difference in how much water you can process. The limiting factor is almost always the teeth spacing of the overflow chamber. This is what limits how much water can enter the chamber. If your plumbing can handle the water flow without a standpipe it will handle it with a standpipe. However, many people have reported being able to push the drains beyond the rated limit by increasing the teeth spacing and reducing the vent hole size which pushes the standpipe to act more like a siphon than a gravity drain. Doing this is risky and you are on your own. I can't recommend it. But people have claimed to reach rates as high as 800 to 1000 GPH with 1 inch bulkheads rated for 600 GPH.

hehe..must have read somewhere off the net that single 1 inch bulkheads drain 600g/hr on the safe side..although up to 800g/hr have been achieved before although this makes the durso pipe acts more like full siphon rather than the gravity feed siphon that it's supposed to be...but heck care whatever type of siphon lah hor..as long as it works..can liao lor hmmm....from what i gather from your post dodo...u are using standpipe of 30mm then reduce to 25mm to shove into the 25mm bulkhead hole....that means the outer diater of your pipe reducer is 25mm so that can fit into the inner diameter of the bulkhead hole of 25mm hor... that means that the inner diameter of the *30to25mm reducer* that u plug into the bulkhead hole is actually around 21mm since the outer diameter is 25mm? Sorry to confuse u if it does....lol....
