Tank design

[steven lee]

My previous 422 tank W/sump had an internal underflow which was'n suitable for sand and undergravel but now I've just bought another 422 tank W/sump but with internal over flow, just discovered that if I put food into the tank it flows into the over flow before the fishes eats them. So which is actually the best design??? Real headache....

You should switch off yr system while feeding.

Just dun on off on off frequently...otherwise yr pump will spoil easily.

u can either do that or just soak the food in a little of your tank's water, once they soak up the water, they'll not float anymore so less chance of them being sucked into the overflow.
