I strongly advice to use 2 separate pumps, to prevent things got expensive and complicated.
AT a head of 1.2-1.5 m which in most cases are, most pumps gets about half the max flowrate. So as I suggested, use one at least 4000L/H. May be you can use Weipro 6000 rated at 4900L/H if I am not mistaken for budget pump. For Weipro 2011 I advice you to go for a 2000 L/H, I am using 2012 with 2500 L/H and feel that the skimmer can accomodate more flow than this, may be can take till 3500 L/H for 2012. |

I try to post a diagram of my intended design of Overflow( or if you been to LCK110 ) , did you see the way the tanks are drilled and a PVC pipe attached , with the top portion connected to a conical shaped pvc. Yup mine overflow will be like that , w/o the additional glass partition enclosing the overflow like most tanks do(is that necessary?) So my logic is drill a 25mm hole with a 25mm overflow pipe, a return pipe 20mm , and as the return pump pump water back into main , water overflow through the overflow pipe back into sump. How do I ensure 1) ? |

I use 25 mm i.d. pipe for about 1500 L/H of flow and the water level is just at thr level of the intake, so if you are targetting 2000L/H you should be enough.
Before you want to know it is enough or not you need to know whjat flow you target first. But not to worry too much as it can be compensated by lowering the water intake, just make sure your sump has enough capacity to hold the water above the intake once the pump is off. |

Thanks for your reply. Hmm do you mean flow rate of pump at 2000l/h ? That's quite a strong pump. Also , do you think the 1.5ft by 1ft by 1ft sump is suitable for a main tank size 2.5ft by 1.5ft by 1.5ft ? Please advise/ |

Yes, I mean an eventual flowrate of 2000 L/H after head loss. Which is about 10+ times turnover per hour. I am currently running at this flowrate and find that it is just nice. Not too strong at all. In fact I need extra circulation or else poops will be lying everywhere in the sand bed. Meaning you need a pump about 4000L/H before head loss. This is not a huge pump. But if you are using a powerhead then this is a huge powerhead.
For the sump size, get one that is as big as you can fit, and then you can have the luxury of keeping extra fishes. This is invaluable to me. I recommend using the standard 2 feet tank (can cost as low as $10), and use containers inside as the “compartment”. I personally do that, my filter media and DSB is placed in side some plastic container, those type where people use to store love letters during Chinese New Year, get the rectangular type instead of the round type and it will be just as neat. Further more you can get to “move around” your DSB when needed. |

Hi NavyBlue, perhaps you can show a pic of the DIY Sump Tank. I have 1 2ft tank lying around...
