Support for OHF (Advice needed)

[edwin14]

Hi guys;

I have a 6x2x2 tank with 3 layers OHF.

I had plugged up the OHF holes so that it holds more water.

However after 3 yrs, the silicon for the center bracing gave way and the whole OHF dropped into the tank.

I'm thinking of getting a new tank to replace.

Any suggestions on how I should do up the next tank to support the OHF so that I do not have same issue again.

Advice form bros here will be greatly appreciated.

3 layers of ohf (15 trays?) is actually not alot.
My last tank center bracing came down after 8 years.
Brand new tank or second hand?
The next tank you need to tell the tank maker your requirements and bad experience.

New tank.

But maybe could be because I plug up the holes so there is the weight of the water also.

U have any additional stuff to support your OHF?

6 ft is long though have the center support. To play safe what I do is let the ohf sit on two long metal rod. I am using curtain railings.

I'm using the L shape bar bought from hardware shop.
In your case, probably need a thicker one.

Using the bars would actually add weight to your bracing so I would suggest unclog the holes.

OHF filled with water is much heavier than a trickling OHF.

addition metal bracing would be good to support the extra weight.

BTW, the OHF was designed for trickling to enhance treatment efficiency.
