Hi all.
Have a 5 year old system. 600L (120g)
Heavy stocked with all sorts. Corals and fish.
Noticed recently more biofilm stuff growing on the glass. Nothing changed to my knowledge except dosing trace elements following a ICP test.
My parameters are all >8.0 - 8.5, pH >8, Ca 440, Mg 1350, salinity 1.024, PO4 0.13mg/l (ppm) NO3 I don’t measure.
Someone suggested in the LFS to lower alkalinity to like 6 to slow growth and increase colour but I thought that high alk stops growth if biofilm?
Any tips?
