Urchins are the only algae grazers that will eat unkept algae problems. Until you manually crop the algaes (and I do mean down to the rock) and keep them that way, the hermits and such will simpley ignore it.
I bought a Po4 test kit and checked it twice. Both times I got a reading of 0-0.25. I let my friend borrow my master kit...so when he gives it back I will post all readings.
It has been mentioned several times in this post and is quite correct. Green algaes are a product of phosphates as are cyano
issues. Even though you are not registering much on the test kit it does not mean they aren't there. Test kits only register inorganic forms of PO4
not organic forms. Any level of inorganic PO4
means an abundance of organic PO4
. If only using RO
water without a DI
attachment, that can be a source of introduction along with certain store bought foods.
Cropping the algae and elimintaing the PO4
in both forms is the only way to beat it. Given your coral density, do not use an aluminum based PO4
product. Be sure to find an iron (ferric) based oxide granular sponge.
