| That is effective too..but now you are introducing something with high levels of phosphate (Phytoplankton) to your tank. Phospate is tough on corals and encourages algae growth. This is why people suggest (just about freaking demand in some places) that you soak frozen food in Ro/Di water and strain it through a brine shrimp net to ditch the now phospahte laden water. (Phosphates are used as preservatives in most foods sold these days). So putting the clam in a bowl where it can be fed w/o introducing the phyto to the tank is preferred over the soda bottle top. You can do it either way, one way just seriously lessens the amount of phosphates you're adding to your tank.
