Recently had this problem of water becoming cloudy and now it's like turning green. Have tried frequent water changes, filter cleaning, reduce feeding and geo liquid but does not help much. Heard that a UV steriliser is quite effective in dealing with green water but rather expensive. Would like to try out the blackout method but not too sure whether it is effective against green water. Anyone tried the blackout method b4 ?
If I were to get the UV thing, what is the spec that I should look at? is it worth investing ? I am having a 3ft tank.
Thanks in advance.
