Coral place against the glass Vs

[minireef]

Hi,

When doing rock scaping.

Is it better to have the coral & lr place off the glass for better water circulation.

Or it is OK to use the glass as a back support.

Advice please, Is it better to place coral/LR off the glass, instead on leaning on the glass

i think its has nothing to do with circulation in the water..the circulation depend on the waves produced by the powerheads & the return pump...

more ppl are concerned that the glass might give way if the rockscape is placed against the glass...but if yr glass is thick enough(eg.>10mm),it shouldn't be a problem...

Up to you. Just remember that some corals will over time encrust onto your glass if placed on it. Water circulation and lighting at particular spots differ from tank to tank so placing off glass does not necessary mean getting more circulation.

Only problem I think will be cleaning algae off the glass surface in future as magnetic cleaners can't pass these areas..

its better to scape ur lr like somewhere at the middle. so that u will have no problem cleaning the back glass for maintaince

Cleaning of algae will be tough. Dun think the magnetic cleaners will be useful. Have to use hand and old credit card. Also, you might scratch your tank if you are not careful and accidently moved the LR. Best to leave a gap between LR and glass IMHO.
