I read the description and didn't see anything about it being safe for salt water? Is it? I know some people do there pools and hot tubs in salt water.
Think it's really cool it can handle sand and then you can just drop it right back into the system when you've collected enough:) Great idea for a big system.

tanks will be bare bottom this will work as a little remote sand bed I can easily clean with the benefit of calcium from the aragonite and the buffering from dolomite....

Doesn't aragonite work better as a buffer? But dolomite would help mag and make a great place for more bacteria?

My concern would be the system's general ability to handle saltwater. Big concern with the pump...is it oil cooled? As a filter, not sure. Sand filters are designed to be used for high flow mechanical, micron-level polishing of the water, usually as a final stage after graduated mechanical filtration through decreasing pore size media like sponges, floss, etc. They're not intended to function as biological filters...they pack up. Also, my understanding is that they are designed for use w/ quartz/silica sand of a certain uniform grain size in order to polish the water (and I would assume the pump is matched to this based on expected back pressure). See this... www.ebay.com/itm/Zeosand-Alternative-Sand-Media-For-Swimming-Pool-Sand-Filters-50-lbs-/181466478906?pt=LH_DefaultDomain_0&hash=item2a403eb93a |

Lance you are absolutely correct. There are a few more issues with using a pool filter the flow rate needed for the sand filter would have a crazy return for a display tank and unlike pumps and filters we currently use on out tanks you cannot reduce or dial the flow back.

dolomite is hard so it wont break up below the size I want it to be for the filter. also there are allot of mag supplements made out of dolomite, so I am thinking it will help.
I am concerned about the pump, if it is an oil pump I will have to spend a little more for one made for sw...
2400gph with a manifold returning about 450gph or less to each tank. explain to me how this is to much flow...

It can definitely be done this company actually makes then for reef tanks but charges a hefty price... seavisions.com/prod05.htmI'm wondering is maybe you could get this unit you listed and replace the pump with a reefflo or iwaki pump? Or if there is other toxic metals in it? |

The pump on that system is a Iwaki pump. Here we go again the latest greatest. All I have to say is DONG !!!!

Do you think you'll be able to find dolomite that is the same uniform grain size as the silica sand this type of filter is designed for? If not, I would expect the GPH to be different (and higher). This may not be an issue as flow is only a problem if it is too much or too little (which varies by application). That being said, I'm still not clear on the benefits. This filter is a polishing filter - you can get the same effect with a lot easier maintenance with filter socks. I'm skeptical that you'll get any "supplement" benefit from dolomite. I was not aware that dolomite will dissolve in a marine tank at the relatively high pH we need to maintain. Even if it does, this filter is going to pack up with mechanical debris and the dolomite grains will become covered in bacterial growth, further limiting any kind of water/dolomite contact. I'm not arguing that a supplement might be derived from dolomite, but I'm guessing that the dolomite has been dissolved in an acidic solution of some sort to free the Mg+, Ca+, or whatever. Thoughts? |

The pump on that system is a Iwaki pump. Here we go again the latest greatest. All I have to say is DONG !!!! They've been making that filter for like over 10 years? And iwaki makes all types of different pumps I meant to say a pump specifically for reefs... Listen not everyone isn't dong and while he's very successful doing things the way he does that doesn't mean it's the right/best way to do things. There's a ton of successful people that use new tech and don't just add tap water to their systems. I mean is the "old school" way only and not using any new tech really working for you?....  As to Robs question like I said that system I posted is way over priced but maybe those modifications could be done your self? It looks as though they took a pool filter like you listed and moded it? |

jason I can get a sw pool filter for around $200 looks almost the same as what you posted... now the question is what do they use for "biomedia"

Easy uses almost the same set up in the 300 gal, his doesn't have sand In it, instead it is a bio media.
