I have a red sea Max nano which is 20g tank with protein skimmer, live rock, live sand, 2 clown fish, cleanup crew, anemone and want to add some soft corals but my phosphates range between .25 - .1. I only feed fish very little every other day and do weekly water changes of 15% or more. I'm already using chemipure & Purigen. This tank has no sump so can't setup reactor or grow any algae. Can anyone recommend anything else i could be adding to tank/water to help lower phosphates?
thx
