Wet / Dry vs. Live rock

[khowst]

To the person asking about "facts", grab even the simplest book on marine (or fresh water for that matter) aquariums, or even the dictionary. We're basically debating weather there is oxygen dissolved in the circulating water in your average fish tank. (or rather enough of it for fish and nitrifying bacteria to live). This is such basic stuff I can't believe we're even discussing it ??

That was me asking about the facts. Thanks for such a snotty reply. I'm glad we were all experts when we started into this hobby.

If it is so basic then why is it being debated?

Although I dont have a dictionary I still pose my original question regardless of who feels they are an expert. If wet/dry is so evil to this hobby why does virually every professional tank, zoo, marine aquarium, etc incorporate some form of wet/dry into thier system. I'm not saying its an end all be all or the onyl thing to use, but it is still a useful piece of kit.

My reply was not intended to sound snotty toward you, my snottiness was directed at sporto.

To respond to your question about zoos, public displays exct; Yes many/most do use wet dry type filtration systems, becuase most of those large public displays are missively stocked non reef systems. Wet dry filtration is well suited to such systems. I never said that wet drys are evil, I said that they are poorly suited to most reef systems.

and thats my point. Whenever someone says wet/dry, someone will scream "nirtrate factory" and start rounding up the posse to go burn down the place that sold it; meanwhile truth be told like I said and you even agree they have thier place and use in the hobby.

 

[jimmyj7090]

Yes, I do agree that wet dry filtration has it's place in the hobby (and I did say so on the last page).

My point all along has been that it's important to understand different methods and where they do and do not fit well. My argument has been with another poster who appears to has been arguing that we universally need wet dry filters to support nitrification / aerobic conditions.

ah, well said. I think I was mis-reading how it was said. My apologies.

 

[jimmyj7090]

Same here

I have read that you have to be careful with replacing the bio balls with live rock. Your live rock would have to be submereged completely in water. If you don't it would defeat the purpose of being "LIVE" rock. You wouldn't grow the beneficial bacteria

??

Not all of the rock will be submerged, but 2/3 - 3/4 of it will be, if you keep it in the wet/dry. The top 1/3 - 1/4 will be just like bio balls(aerobic bacteria), but the submerged will act just like the live rock (anaerobic bacteria) in your display tank.

YES this set up right here!!

Here is my new thread on my sump I am having problems with please help?

So are you saying that you are also under the impression that there is not any aerobic bacteria on the rock in the water? By extension, there is no O2 in the water?

Please say No, and then clarify what you mean, please....

No, just that the lr in the sump that is submerged, functions as does the LR in your DT, both aerobic and anaerobic. The lr that is not submerged, is aerobic mainly. That is why I have as much of the lr as I can submerged.

You are getting good advice in that thread.

Thank you for the clarification. I agree 100%

I know I am, nothing against him. Just wanted to see if anyone else wanted to pitch in.

Quick question now I'm thinking in having a small bed of lr rubble in my DT. So I can have some snails, and a good crew cleaner. Is this fine?

 

[jimmyj7090]

Rubble might not be the best idea as it would make for an ideal spot for detritis to settle and be trapped.

True, can they walk on bare bottom glass?

 

[jimmyj7090]

Yup

 

[CarlitosReef]

Yup

Cool thanks.
