reverse wet dry. any one ever use on like this

[mike dunagan]

agreed with last post...and I have some that are total submerged like yours...

As long as your tank's healthy and the parameters are good there's no need to worry. Most people have too much filter media anyway, which isn't necessarily a bad thing, but bacteria growth is usually limited by oxygen and bioload, not the lack of surface area on filter media.

Thank you for your replie. But yes i agree on what you are saying. I am the king of over filtering. I am not worried about this not being enough filtration after all this is a huge sump for a 29 gallon aquirium only 3/4 full of water I am just curious if any one has a proven answer to what the percentage difference is. in submerged and unsubmered bio balls. And who has done it and what the debate is on it i guess. Again thanks for you'r replie

Any percentage of effectiveness would be guesswork at best.
The amount of variables in your question would tax even a well equipped lab.
Saying wet/dry is better than submerged is another yes and no statement.
Would all depend on the dispersion of water over the media, or the flow pattern through it.
A bio chamber with good flow patterns and well filtered water would kick butt over a wet/dry with poor dispersion and iffy pre filtering.
Overhead filtering is a very good idea that has just not caught on in the west.
As said, it is a very popular type in the east.
Seen a number of DIY projects on MFK using anything from window flower boxes to full on acrylic builds.
They are an excellent filtration method.

Looks similar to the "Wendy" filter. It's a filter that a lot of people have used for turtles but I've never seen been used with fish really. It's basicly and indoor version of the Skippy pond filter and works very well for turtles as it's overkill which is good because turtles have a huge bio load. I recently have just finished hooking up one I made for my painteds and red ear slider. It hasn't been hooked up for that long so I really can't comment how well mine has worked but I know for other turtles it keeps the tank spotless.

submerged biomedia reduce actual water oxygen when the bacteria take the O2 directly out of the water. Having the biomedia OUT of the water and allowing the water to trickle over it allows the bacteria to take the O2 from the air and not rob the tank water of needed oxygen (this is the preferred method with a trickle or "dump" style filter). What the percentage differences are, are minimal, but on a heavier bioload (a more crowded aquarium) it does make a difference to the fish since they get their oxygen from the water. If your fish are doing fine and the parameters are within normal limits, as stated above, then don't worry about it. I know I wouldn't lose any sleep over it.

I never thought of it this way before. With as you said it takes more oxygen out of the water. But i guess that wouldn't apply to this tank sence it is a turtle tank right. Thanks for you'r reply and this point of view would make a strong argument if this was a fish tank not a turtle tank. thank you

thank you for you'r post could you post pics of you'r filter set up here for me. Or paste the link to the thread to this thread thanks for you'r time.

Hello guys,

I have never seen any one use a wet dry this way. Or ever done it my self untill a couple months ago i rigged it up this way. I am curious if any of you guys ever have or ever seen anyone use one this way. My guistion for the most part that i know has been covered before is. In the way i have this set up is about 6/8th of the bio balls are completly submerged in water instead of the water trickling over them. So what is the comparison on hell well they work this way to the regular trickling water over method. As you can see i put the sump on top of the tank on a stand and put a hole in the side to make a waterfall back into the tank. And the pump is siliconded to to the tank and pumps water to the sump instead of the normal way the other way around. WIth just filter floss on top. So i'm looking for you'r views of how well the biological filtration this way works. Allso i have had it set up this way for a while with no problems of the pump getting clogged from being in the tank it self. And the water is crystal clear. This is a 29 gallon tank. Thanks for your views and your time and comments.

Nope, never used one. It works a lot like a waterfall box for an outdoor pond.

turned into an overhead filter

I'll try to track it down - even have some step by step build pics...

I have a big rubbermaid of bio stuff I've accumulated over the years: bio balls, scrubbies, army men, lava pieces, those ceramic combo looking things.

Thanks for your responce can you post a pic in this threed for me. And include what it is that you use for bio material thanks again
