sw pool filter?

[mainereefer]

I am wondering if anyone uses or has used a sw pool sand filter on a reef setup?

pro's,cons, thoughts? any info would help. I know large aquariums use them but is it worth it on a 300g system?
if so what would be used for media? my thought would be dolomite because it wont brake down so it would stay a uniform size.
but what do the pro's say?

High Flow Filters

I wouldn't see any problem using one of those. Same thing as a fluidized sand bed filter, only much bigger.

my concerns are, how much water would it take to flush the media and what would be used for media?

All that is is a sand filter for pools, but plumbed in a closed loop type fashion. The way I read it, you backwash it without loosing water. Maybe just change the media yearly or so?

I had wondered the same thing before. Check pool places, I just bought one for our pool for 200 not 2000!

I would think youd only have to backwash it once a year, being as its not there to catch such large debre lime it would from a pool. But id remove it fromnthe system and run a hose through it for the backwash.

I am looking at the filters on ebay for around $200-$250 the price on the one in the link I posted is crazy I just posted the link so ppl would see what I am talking about

I am thinking of the filter like using bioballs they are great aslong as you can flush so they dont become a nitrate factory, maybe?

I wouldnt' use bio balls in there, the sand will grow sufficient bacteria, providing you don't use FW to flush it out with. But if you use SW that will get expensive in itself. I'd just use it as a filter and flush it out with FW, not worrying about the bio capacity.

with the sand I am worried about anaerobic bacteria being created and disturbed causing problems.

now I this filter was 0n a 300g system with say bio-balls would the 40-50g waterchange every 2 weeks be sufecient to flush them. or is a filter sock the same thing with allot less hassle?

 

[Reefing Madness]

Yes, if you backwash it every couple of weeks, then you won't have to worry about that happening.
