just got a coral life twist. Its greatNyquil Junkie;2744640; said:Once the gren is gone you take the thing out of the tank and put it away... you dont have to leave it running 24/7. plus, its a handy design to clean up the water of you suspect disease or parasites. Run the submariner for a week, then take it out of the tank..... its self contained with its own powerhead and flow regulator, sticks on the tank with 4 suction cups. Easy... clean.. versatile. it can be run upside down, sideways... any way you please. you can buy a coralife turbo twist one that hooks up outside the tank. they are good too.
by pouring phosphate into the water source thus coating pipes with algae . In theory they didnt leach lead if coated with algae.
