Hydrogen Peroxide Works Wonders on Algae-Ridden Filter Tubes

I just replaced my filter and I wanted to clean up my old one as best as I could before I put it away in storage. I was having trouble cleaning the hard to reach spots in the tubing though (it's an AC 50, so like the U part of the intake tubing and even the part of the straight tubing that I couldn't get at with an old tooth brush).

So, considering most of it was just brown algae, I thought I'd give H2O2 a try. Worked wonders. Just capped one end of each piece, filled it up with H2O2 and left it over night. Rinsed it out in the morning and it's good as new...looks as clean as when I first got it.

Thought I'd share this in case anyone else was having trouble with those hard to clean spots :thm:

that's where I got the idea from. I've used it in the past to clean BBA, so figuring the brown gunk was diatoms (brown algae) I thought it might do the trick.

I've only used this to clean the tubing since this is the only part of the filter that I can't get at with a sponge or paper tower or something. Coach_Z that's a great idea though. Probably wouldn't be feasible with H2O2 but bleach works just the same I'm sure.

And no H2O2 isn't hazardous to fish, at least not in these quantities. It can be in larger quantities, so don't go dumping a bucket of it into your tank (even if it is just H2O with an extra O, it's a lot more reactive than H2O and will screw with your water chemistry / hurt your fish if you use too much).
