View Full Version : Scrubber Box

04-22-2010, 02:54 AM
After installing a "TEST SCRUBBER" in my tank almost a month now i have every day been looking to find a way to make a bigger and more effective one. ;)

And finally i figured the best possible way to update it so it can be powerfull enough for my 240 gal.

I found a plastic box (those that people use for storage) with a lid.
i'll post a pic later...

My question is...

Should i use the boxs' lid and drill some holes for air OR keep the top completely open?

Does this play any major role? :?

if you have a lid on it you will get less evaporation

Air will not affect the scrubbing. It only affect cooling and evap.

With the top on there are chances you'll need to use a fan to cool things down. My 55g and 4 23w cfl overheats my tank so I have a 120mm fan that comes on when the lights do.

So a closed or open box will only affect evaporation and slight change in waters temperature?

I'll give it a try later today and ill post some results soon.

I thought that a closed scrubber box may increase the growth...

No, a closed box will only keep the water from cooling down.

Is it better if the box is painted a dark colour?

so no light escapes to the rest of the sump and no other growing start outside the screen and box...

you need to reflect the light back onto the screen but you dont wont the light escaping so that algae grows in the sump. so ideally you wont a black box with reflectors behind the lights .
