return pump question

[mandown123]

I have a 30 gallon with sump (10-15 gallon?). I need to increase the flow in my tank because the return pump is very weak - the one that came with the filter.

I was wondering what i could get away with because the tank will have to have a balance between overflow and return, correct? I am new but this seems logical i cant just put in the biggest pump i can or it will mess up the level of water.

Can anyone advise/help me out to understand this.. What is the best flowing return pump (and quiet would be awesome) i can get away with with that setup. The drain pipe is like 1" wide

a 1" drain pipe is a good choice. All you really need to make sure of is that your overflow has a rating that matches up with your return pump New Acrylic Overflow Box and Skimmer Box for Saltwater Aquariums This is the overflow that I have. works with a mag5 or even a mag7 I have a mag7 on my 46g tank. the mag5 would be a better choice for a 30g MagDrive 500gph Water Pump: Premium Aquatics

1" PVC allows for 600gph drain. A MAG5 or equavalent would work well for your size tank.

[mandown123]

is that the good one? the mag5? I will go with this one if its the best bet.

Thanks, you guys are the best.

Danner pumps are very reliable and have good reviews. I own two a Mag5 and a Mag7. They can be used submerged or inline. Look for them online you will save money over buying them at an LFS.

i just looked it up, i think i have a CAP 1800 pump. is this mag5 better or is it like the same?

[fijiwigi]

CAP Aquarium Water Pumps Jacksonville Florida it looks like the Cap 1800 has about the same GPH rating as the danner mag5 I don't know how accurate that is because I have never had a Cap1800. I am happy with my danner mag7 very strong flow You could always continue to use the Cap1800 and add more flow with a strong powerhead

thanks maybe i should just geta maxi jet

IMO mag pumps are the best. I have the mag 9.5 and mag 12 and they are reliable and quiet.

Mag's are great pumps, but they do add some heat to the water too If you only need more flow in the tank and you already have a pump rated for your overflow, then you should add some power heads. Look at the Hydor Koralia's and MaxiJets.

[Ziggy953]

I agree with Cmor. If you don't need a new return pump then pick up a koralia they do a great job of adding flow and they use very little power.

If you do need a new return pump you will do well to get the Danner Mag pump.
