Tak for indlæget,
For meget jern?,
Jeg har haft en mistanke med mit JBL Ferropol fordi mine penselalger begynde
efter at jeg begyndte at tilsætte JBL Ferropol.
Jeg tilsætter JBL Ferropol fordi jeg har problemer med at holde de rødlige
planter og min FE værdi var 0, nu er den ca 0.3 mg/L (ppm) men jeg har
stadigvæk problemer med de rødlige planter.
Jeg tror at jeg vil stoppe med FE tilsætning i et stykke tid og se hvad der
sker
