    Bakki Shower media question

    Hey Guys
    I'm in the process of building a Bakki Shower filter for my pond and I would like to know what other shower filter owners are using as far as media goes for their filters. I'm making a 4 stage shower filter, so in here's what I'm planing on putting in the boxes:

    1st Box: I'm going to place Filter Floss type media like this..
    http://www.amazon.com/FILTER-MEDIA-F...ir+filter+roll

    2nd Box: Large Bio-Balls
    http://www.amazon.com/Green-Vista-BI...+bio+balls+1.5

    3rd Box: Lava Rock
    http://www.amazon.com/CerMedia-Marin...rium+lava+rock

    4th Box: Filter media with Carbon sandwiched between sheets of media.

    Also I plan on using my UV after the filter box, so water returning to the pond should be just about perfect. I would appreciate any feeback and tips you guys can post. I'm really looking forward to building my pond. Thanks in advance for any help.

    Technically a Bakki Shower filter uses Bacteria House filter media. IMO stage 1 and 4 do not contain "shower filter" media.

    Welcome to Koiphen!

    I use only feather rock. It's lighter than lava rock but looks very similar. I wouldn't use
    any form of sheet material other than maybe the top container to catch larger debris... but
    with a good prefilter you shouldn't really even need it.
    It's a challenge to gravity feed your uv. I'd put it between the pump and shower if possible.

    I would not use ANY of that stuff.
    If You want to use matts , at least use the Matala. Matala has 4 grades and the finest,gray,would work good in a shower.
    Bio balls don't have enough surface area.
    I consider lava rock useless, it is not porous,it just has a rough texture that bio could stick to,but lava rock is too small and will pack tight. It will eventually clog up and is a pain in the butt to clean.
    Most of Us like feather rock, it is light and porous,and cheap, sometimes hard to find.
    That Cermedia is way overpriced, the going rate on Cermedia is a little over $100 per cu.ft., and one cu.ft = 7 gals.
    So at that price of $43 per gallon, You'd be paying $300 per cu ft.
    There is a vendor on Here ,Seaside Aquatics,that has just about Every media possible including Matala, give Tom a call and get some advice.

    Replaced my lava rock with the media from Seaside and the water improved greatly. I use green Matala in the top try 3 sheet thick.

    What did you replace it with and what was the final cost per cubic foot?

    It looks like to me that you take media that is $100/cu ft and magically manipulate your numbers and triple the price. How does that work?

    I was quoting you and questioning how you turned cermedia that was $100/cu ft into cermedia that was $300/cu ft in two sentences?

    Gloria, the link that the OP posted for the Cermedia is for a 1-gallon bag of randomly-shaped pieces for $43. Jeff was comparing the price for the Cermedia squares.

    I like feather rock, It's usually pretty easy to find and if getting bigger pieces, it's pretty easy to break into smaller pieces with a hammer and chisel. And much cheaper than any of the man made products.

    looking at your thread.....
    http://www.koiphen.com/forums/showth...tarted-already

    no skimmer, maybe a bottom drain? a 55 gallon trash can pre filter, no TPR's. and going directly for a shower filter. living in WA. i would say. look for other filters. (assuming WA is like illinois) and gets down into single digits in winter. for a few weeks.

    i am not nocking bakki showers, they are awesome filters, but to much focus on single type of filter. vs overall filteration setup.

    i would more likely consider a bakki shower for warm locations example texas / arazonia / flordia, etc.... due to bakki showers require a large amount of air exchange to do there thing correctly. a TT (trickle tower) is a smaller more compromised version of a bakki shower per say. and could be used in summer. but not be your full filtration.

    water changes and stocking rates and other factors play a big factor into it all. but i would shy away from a bakki shower. and get ya looking at your inlets and outlets on your pond first, skimmers, bottom drains, TPR's, waterfall/streams first. then start looking at filtration that works better for your inlets / outlets.

    sand and gravel filters, RDC's, sieves, settlement chambers, foam chambers, a huge variety of DIY and professional built filters out there. some filters require to be set at water level of pond, some require more detail to pump placement, some filters need to be placed before other filters to work better, some filters need to be placed above pond water. and have a waterfall or like return water back to pond. some filters are pressurized and others are gravity filters.

    and yes i am picking on you. and is more of an attempt to get you to continue researching and looking at other diy filters out there so you better understand how you build them. and what function they serve. it takes some time and asking questions. but a little bit time now. really pays in the long run!
    Pond and Construction Forum 101 good place for any first timers to the forum. for finding resources and general info.

    Ok I am confused????? What is Pumice? What is Lava Rock? What is Feather Rock? I thought they were all the same but different names? Please could someone explain the difference to me?

    You can Google the info the same as we can:

    https://en.wikipedia.org/wiki/Pumice it has a fine texture like a sinter glass material (i.e. Crystal Bio) It is light per volume
    https://en.wikipedia.org/wiki/Volcanic_rock very rough texture like alpha grog.....but the lava rock at the DIY store may be metal foundry slag....it is heavy per volume
    feather rock similar to pumice....another volcanic rock

    Another inexpensive choice could be Growstones Lift. Lift is larger size pieces than the GS-1 product. For those that don't know Growstone products are sintered glass. You melt down recycled glass and mix in chemicals (calcium carbonate) that give off gas that causes all manner of very fine bubbles to form. Then the product is cooled broken into pieces and packaged. It is usually aimed at the aquaponics market.


    Ogata Koi Farms has sintered glass marketed as Crystal Bio. http://www.ogatakoi.com/eng/dry_goods/crystalbio/ You will see it alot at UK koi dealers. http://www.absolute-koi.com/prod1546.html Crystal Bio sells for around 150 Pounds for 100 liters....roughly 4 cubic feet. You can get Growstone Lift for under $50 for 1.5 cubic feet at Amazon. https://www.amazon.com/Growstone-714...growstone+lift

    How large are the Growstones Lift pieces? They look too small.
