32 mm I measured inside diameter and that was 28.

yeah, but it's called 32mm measure inside diameter of pump it will usually be same (or slightly less) than the inside diameter of the pipe. most pumps are 3/4" (20mm) or 1" (25mm) so that should be sweet

I have instaled lights back over tank two 150 w halides , have got new sump 1m x .6 w x .45 h .Painted back of tank (well got 8 year old daughter to do this) black . But just a question to those with remote sumps were do you control the return pump from , tank or sump or both.I 've always had sump under tank so if any overflow problems everything is there but if the pump is under house I'm either going to wire pump to garage or thru floor to tank.

mines plugged in outside,i would like to be able to switch it off from inside tho!

But just a question to those with remote sumps were do you control the return pump from , tank or sump or both

both. got power switch on wall in sump room, but this is also controlled by a switch next to the display tank upstairs (incase of emergencies, break glass )

thanks I'll wire with two switces tank and sump.

are you going to have your return pump hooked up to a UPS? if so factor this in - you will need to have switch wired up on ups output, not input.

I will not be using UPS just into a power point in garage . I have been doing some plumbing for tank today and did test with pump all seems okay I am pumping 2250 liters an hour back to tank which is turning over tank 3.5 times per hour .tank size 643 l and sump 162 l.

Changed Pump to a Laguna 7 and put it next to sump , changed piping back to tank to presure piping and I'm getting 3600 L an hour .

Increased duroso stand pipe to 40 ml and this has made big difference in controling water highs by size on hole at top of duroso.

Tank is full of water and I will be swapping over rock fish and corals soon.

Laguna 7

blinkin cheap too

:bounce:

Laguna 7

Yeah they're crazy, when I got mine we chucked it in a bucket, plugged it in and an initial blob of water shot waaaay into the air.

I also gave it a jam on my weipro :lol: , although the piping diameter was too restrictive - it still looked psycho.

Haha my 280L tank's gonna need its seatbelt. :lol:

How much noise does the laguna 7 make - I want a silent pump - 3000 litres an hour.

great pumps, replaced my 6 with a 7 recently, but not silent.

The lungna will pump more than twice that. I have two of the found them to be a little bit noisy, give out a low hum

Sup did u rubber mount it/? If so it might be hard to get a pump for that kinda price that will be silent?

one (the return) is on its rubber feet, the other is on its side driving the skimmer. The tank they are sitting in is sitting on top of a hollow cavity as well to make things worse. Don't get me wrong I'm totally happy with them and at fantastic price for the water they pump let alone how well built they are. I paid more for the resin king 4 I have driving the skimmer in my old tank, it uses almost as much power pumps half as much water and generally crap.

ditto, no complaints at all with the pump, and can't hear a thing in the shed from the house

would carpet work or is rubber better to get rid of the hum .

:lol:

Moved everything over today to new tank .Bubble coral may not servive has been looking a bit ragged in holding tank lost a sps due to galaxia did'nt spot the long tenticals in time but managed to save a couple of cutings off the end .

Nice aquascaping, this is going to be a good one!

sweet

3 halides would be the one though i think.... i should have gone 4 on my 1800mm tank, only have 3 :-?

I have an old 250 w I might try later .water looked a lot clearer this morning I but in two bags of charcoal and one had moved to block the tank return so water was being sucked thru charcoal.

those sps will love the 250 that water should clear itself up in a couple of days. asw or nsw?
