Ohf
 

Can find locally? The base is aluminum and will not bend easily. The rain bar is bigger instead of 1 row. The plastic is like thicker, uv light shaded, anti overflow and all are drawers type. The bottom tray flows like sump.

dead link leh......

I guess is mobile link. Need to use mobile to view.

Go for glass base.
The trays are smaller.
See people selling used ones so I guess it is not good enough after awhile.

glass will not bend but heavy. aluminium is good enough. at least better than plastic. u mean this tray is small? 2 is equal to 1 mr aqua. can get locally? you know the place and price? i see this is better than mr aqua.

Overhead is bo good. Use a canister.

prefer sump and ohf.

Very troublesome when changing filter wool, need to drain all the water inside, carry to toilet and wash. After washing must ensure the canister is full filled with water otherwise cannot start again.
:(

if the mechanical filtration is on top then is still ok. just take out the wool will do. canister if choke is a disaster. i dont like to turn on and off the pump so often as i feel will spoil faster.
