White Spot Treatment

[Far_King]

IIRC this filter is hidden in the hood of the tank.  As it's Aqua One you may be able to get media that will just slip into the filter.  This would be best but I'd recommend either awaiting advice from someone on here who has one or asking in your LFS.  I've never dealt with these filters so I don't know how straight forward they are or if it's possible to cause issues with them.
 
I do know that the tank is not suitable for keeping clown loach in sadly.  165 litres is not enough for a fish that can grow to 18 inches long.

I read on another post about the size they can reach, but didn't have the heart to tell her, as I don't know how long she's had them for, (thanks for the advice btw). The remaining on is about 3 inches.
I'm not to clued up on the filter myself, The filter has got (from bottom to top) noodles, blue coarse and fine sponge, which I put in, then a polly pad. I wish I'd taken some pics now

Sadly she will find out sooner or later.  Later will be worse for the fish.

I've not seen this filter either so it's difficult to advise. What I can tell you is carbon is useless for anything other than removing medication - it can help with the smell but if you don't like the composty smell of a healthy aquarium then your in the wrong hobby in my opinion
 
I do agree with Far_King in that this tank isn't really big enough for clown loaches, the other problem is also that clown loaches are social fish and so need to be kept in a group of their own kind. Kept alone this fish will suffer and though it may be difficult to explain this to your friend now might be a good time to sit down and have a chat about it. White spot is normally caused by stress. It can be passed from fish to fish on contact (ie sharing a tank with a fish that has it) but it ultimately comes from stress. This is why it's fairly normal to see newly bought fish going down with it. Perhaps if you explain this to your friend they will see that keeping this lone clown loach is only going to make it sick and that the white spot is likely to return given that it's living in a stressful enviroment (ie - a small tank and no friends) 
 
I hope that helps in some way, sorry I can't be of more help

I know ,
I've just seen the original filter set up its noodles, black sponge, carbon cartridge, am I right in saying the carbon just absorbs any treatment that's been added, but will release it after a length of time. I haven't used carbon for a good 5+ years

I'll admit to only having limited knowledge of carbon as I don't use it. I have used it to remove a medication and I just added some to a seperate internal filter I had (my tank has 2 large external filters normally) and removed it after a week and did a larger than normal water change (50%) to be sure I'd got rid of the medication. My best advice would be to aim to do the same and just throw the carbon away after a week

Thanks akasha..I've already done the 50%ish so just a case of the carbon.
