found a tank:slayer: +- 340 l

got it from angel. pretty sweet setup. gonna set it up next weekend! some serious FUN.


few questions: 1) have an 8000l/h pump. would love to use it but im a bit scared it's too much as a return pump. was thinking about making the return pipe a "line" of powerheads at the bottom of the tank all blowing up onto the LR therefore no/few powerheads... make it out of PVC. what u think? oh and the tank has an overflow box in DT with a 50mm hole...

2) got a 9watt uv steralizer. says its good for 200l. should i then leave it on permanently?

I think 8000 is ok as long as your overflow can handle it,coz you do not want to flood the tank,wet carpets or wooden floor,eish...

wicked cool.
just check if it works, some pumps are highly rated and can't pump very high(from sump to pump, they lose their oomf)

don't use the sterilizer, it wil only be effective above 30W,needs to have a quart sleeve for marine systems

Good going Geoffrey, well done and welcome to a awesome hobby.

1. 8000lph is quite high, I've got a 6000lph pump on a 520L system and I have to 'dump' some of the flow, so 8000lph could be a bit much but like Lanzo siad, check the rating at the headhight (height from sump water level to tank water level) of you system. I would not run return piping to bottom of the tank as it will act as a syphon pipe when the power goes off.

2. There is a lot of contravercy on this, I personally would rather not use it, I believe fish get use to it helping and when it stops, all hell breaks loose....

ah.will post a pic of the steralizer when it comes. but it says on the box its suitable for salt water. why not just use it and run it 24/7 (as it is ment for 200L not my 340L)

1.5 might be a bit low, std tank is about 1m - 1.5m. that would mean you would almost loose all the flow, but check it out. like you siad, you can split the output using a vavle on the one going back to the sump.

you can submerge the return pipe a bit, and make a small hole the the piping above the water level, a syphon break, it will suck air causing the syphon action to stop.

Take note. Very messy
Investigate closed loops. Sounds like the answer

lIghty- yeah i though about that but u beat me to it... got all the glory!!:p

will it be a good idea though. ie for water flow? to have my return pump acting as multiple powerheads?

that's exactly what's called, does the pipe just connect to the bottom, (ie. it will drain the overflow completely empty) or does the pipe extend up? 50mm should handle, I've got a 32mm down pipe and pushing about 4000Lph.

What a question. Of course. Think of the benefits. The main one imo, your fish will not have this constant unnatural buzz in their ears

I doubt it. Can you have an extra 50 mm drilled.

no the pipe extends up to just before the overflow. gonna put a bend there to make a durso effort. reduce noise (Its a tall tank: 650h) which is nice.

im gonna be transferring all the stuff from my current tank into this new one. any specific method to doing it. steps etc? have about 8.5 kg LR and 2 damsels. they can chill in my sump while i get things ready.
