I have a juwel rio180, fitted with 2*45w t5 lights and pressurised co2 injection.
With a KH of 11 and pH when injecting co2 of 7.1 i'm sure the co2 level is ok, no3 level is high (too many fish), phosphorous level is about 2ppm, am dosing K to about 20-30ppm and am adding something for the trace elements.
When i do a water change (40-50%) the plants start to pearl amost immediately but the next day nothing. any ideas what i'm missing ? obviously the new water is adding somthing i'm missing but the effect is very quick....far quicker than i'd imagine any fertilizers can be taken up by the plants.
thanks,
Rich
