Video clip of the foaming..... MOV00756.MPG

after the addition of Bane's Venom.... the skimmer started foaming crazily.....that said, i am impressed with the speed at which this skimmer picked up the foaming almost immediately. At this point, I cannot conclude if it is the virtue of the skimmer or the potency of venom. but meanwhile, let's just leave it to the skimmer to foam away.

50ml of Bane's Venom.......actually just the skimmate diluted with water from my quattro lah water in tub (about 35litres at 1.026) before addition of Bane's Venom around undetectable to 0.5ppm of nitrates....tested using salifert. will measure water nitrate values daily.

Sicce Extrema insump drawing 4l/min of air (240l/hr), similar results to round 1 insump testing. no flooding problems here.

But one problem surfaced during this round, foam came too fast up and flooded the cup..... ie.....thus it's probably better to stick to manufacturer's published air flow of 220l/hr and the 660l/hr water flow.

Round 2 of testing: Eheim 1262 insump drawing 6l/min of air (360l/hr), similar results to round 1 insump testing.

The other way to check if the pump is suitable for the skimmer is to measure by the water pass the venturi/exiting the skimmer.... It is actually 660l/hr for the 1000V and 1300l/hr for the 2000V. This means that the Eheim 1260 with 2400l/hr water flowrate at 0-head, passes through the venturi/exits the skimmer at only around 660l/hr in order to suck in air at 220l/hr, this shows the great restriction the water flow faces at the venturi. Similar using the Eheim 1262 with 3600l/hr water flowrate at 0-head, passes through the venturi/exits the skimmer at only around 1300l/hr in order to suck in air at 400l/hr.

From the website.... http://www.aquacare.de/produkte/acf/e1acfv_n.htm The 1000V published airflow is 220l/hr with Eheim 1260 the 2000V published airflow is 400l/hr with Eheim 1262 Recollecting earlier airflow results: Outsump 'long-hosed' Eheim 1262 = 240l/hr (near published airflow) Outsump 'long-hosed' Sicce Extrema = 120l/hr (grossly under published airflow) Insump Eheim 1262= 360l/hr (very much over publish airflow-bordering to next higher model 2000V ) Insump Sicce Extrema= 240l/hr (near published airflow) Just like they recommend the Eheim 1260 for 1000V insump use, the water flowrate of 1260 is around 2400l/hr....which is very similar to Sicce Extrema's 2500l/hr....thus the 1000V published airflow is 220l/hr is similar to in-sump extrema's 240l/hr of air Thus, I reckon that irregardless of what pump in watever situation, as long as we hit the manufacturer's recommended airflow rate of about 220l/hr of air, the skimmer should be working as what the manufacturer expects. In other words, you should use a pump 'as powerful' as the eheim 1260 for insump use that would enable the skimmer to suck in air at 220l/hr. The sicce extrema in this case is a suitable substitute. If you want to use the skimmer outsump and deliver water via long pipe/hoses, you will need a stronger pump than eheim 1260 to overcome the water flow loss and generate a flow at the venturi as strong as the insump 1260 would. In this case, the eheim 1262 via long hose is a good pump for outsump use.

bubbles from eheim 1262 insump

very dense bubbles from the eheim 1262 insump. will conduct a few rounds of testing insump and outsump these few days to confirm the readings again

Using the eheim 1262 insump, it was able to pull in 6l/min of air... 6l/min = 360l/hr of air yes, i would agree the skimmer performs best insump with the pump installed as in the manufacturer's picture

Insump use: Here is where there is a great improvement. airflow: 4l/min = 240l/hr Using the sicce extrema, it was able to pull in 4l/min of air...similar to what the eheim 1262 could do in the earlier outsump configuration with a long hose.

Pic of bubbles generated at 120l/hr

Outsump configuration with Sicce Extrema: Air reading: 2l/min = 120l/hr Bubble density is very bad....again badly aggravated by the use of the long hose. Conclusion: for outsump use, please minimise the length of hose/pipe used to deliver water to the skimmer.

a picture of the full chamber..... the long hose that i use to deliver water from the eheim 1262 to the skimmer is reducing alot of flow especially when at the end of this flow is the skimmer's venturi waiting to restrict the full flow even more... But when this long hose is changed to much shorter hose later during insump use, you can see the difference in the reaction chamber and air readings. (this goes to show that even a good pump like eheim 1262 is facing considerable flow loss via pipe/hose length as it is still a non-pressure rated pump)

Outsump configuration with Eheim 1262: Eheim 1262 placed in sump....delivering water to the skimmer via long hose.... Air reading: 4l/min = 240l/hr Bubble density reasonably good but as frozen by the camera, there are still pockets not occupied by bubbles.

Will be running the review in both outsump and insump sections.... as can be seen from the manufacturer's website....this picture shows the pump mounted just on the mounting plate of the skimmer directly under the venturi, this is their suggested insump configuration. What i do for running the skimmer outsump is to put a pump in my sump and then use hose to deliver water to the venturi and then add piping/elbow to the discharge outlet of the skimmer to return water to my sump.... I shall start with outsump operation. Pumps used are Eheim 1262 (3600l/hr at 0 head) and Sicce Extrema (2500l/hr at 0 head)

yeap.... objective review will be in order.... good will be said....bad will be said as well..... First impressions: Well built, none of those "weipro or macro" type of feel.....in layman words, feels solid and strong. Fittings are quality VDL pvc fittings and pipes. But the "clear" pvc used for the collection cup and skimmer body cheapens the design as cast/extruded acrylic would have provided a much clearer view of the reaction chamber and adds *gloss* to the design. Thus even before u fire up the skimmer, you already have to face a "cloudy" looking reaction chamber. Thus in terms of build quality and aesthetics, it is ahead of weipro/macro equivalents but the use of *clear* pvc (which actually is more cloudy than clear ) is a niggling point to me personally.

Height of skimmer: 61cm Total height you need in order to remove collection cup: 63cm Footprint: 17cm x 33cm more dimension and details here... http://www.aquacare.de/produkte/acf/e1acfv_n.htm

managed to plumb it up today.... very surprisingly the daeil is not too noisy as compared to the artica with the mod...in fact...the daeil beats the pre-mod artica when it comes to which one is more quiet.... the modded article has a lower drone sound as the chiller fan kicks in...whereas the daeil has a slightly higher pitch whirring sound as the chiller fan is in operation. I attribute this difference in pitch of the whirring sound due to the different fan motor/blades of the fan itself. I do not have a decibel meter with me to judge each chiller. So all i can say is that while both chillers are too noisy to be put indoors for noise-sensitive reefers/households, both are about as quiet/noisy as each other....with the daeil fan registering a slightly higher pitch in fan sound than the artica...

what do i think? nothing much lor..except you got high standards and good taste even when new to the hobby lor... when i was new to the hobby...all i thought about were clownfishes and damsels

yup, the AT is mine...he will be one year old in my tank in a few weeks time hope to see you in singapore one day
