lava rock vs bio balls

  • We are currently upgrading MFK. thanks! -neo
Wow, what a bargain find! You are good! I've never seen a great deal like this on scrubbies.

Thanks for the link, I am enjoying the vids and read. Any shots or videos of the filtration system in action?

Thank you. I am averse to talking about my stuff in someone else's thread, albeit the media, the topic of this thread, is 1500'x10' 50% shade cloth. The pics and videos of this filter (15,000 gal ~20'x20'x6') in action or not in action are the same :) Everything happens well down below. One does not note much of a current at all at 15,000 GPH. It's like watching grass grow.
 
Here's my filter setup. Pump is in the pond and will be coming in to the filter via a pvc pipe in the middle of the barrel.

Right, that's roughly what I pictured. I'd move the barrel up just enough so the water flows down the filter and outflows into the pond (above / at the surface) from / at the bottom of the barrel.
 
Your barrel filter is an up flow "Skippy" design right? Do you have a bottom valve back flush feature? I am thinking that is the pvc pipe in the cinder blocks?
 
Heretix, you have convinced me that I need an intex pool, shame on you! ;)

I see no problem here. ;)

I actually did think of doing that originally, but I didn't like the idea of having to climb on a ladder to clean it, and the possibility of an overflow of the barrel if the media gets clogged. 4000gph with clogged media is a lot of water loss. This design, if the media gets inundated with waste, the water will still move around it and not overflow the barrel. So if I were to go away for a month, I wouldn't have to worry about losing all the water in the pond and thus my fish. But mainly it was the not climbing on a ladder to clean it thing :)

That's exactly right. it's a 3/4" bottom drain. I actually tested it out last night, and it works PERFECTLY! backwashing and water changes will be SUPER easy.

Understood. Everything has advantages and disadvantages. Wet/dry if set up right cannot get clogged because there is a lot of empty space for water to run down and take lots of air with it. The cleaning: if your mechanical prefilter is good, you'd not need to clean your wet/dry except perhaps once a year if that. And to mitigate the ladder thing one could stack up some more cinder blocks around the filter and have a sturdy, safe area to inspect and service the filter.

Again, needless to say you do what you feel is right for you. I am merely thinking aloud.

I totally get what you're saying. And really this was easiest for me to set up with the current situation. Changing it in the future will not be hard or expensive really. I'll see how this method works and go from there.


I actually found that link the other day and posted it everywhere i could. Saying it's a good thread is an understatement.
