Acquistato in sostituzione del filtro integrato del mio Askoll Pure XL 94 litri. Con i pesci Oranda, che sporcano moltissimo, il filtro integrato nel coperchio non era sufficiente a garantire una buona filtrazione. L’acqua era sempre torbida e piena di impurità. In più il precedente, essendo integrato nel coperchio di plastica, era estremamente rumoroso. Questo Fluval è incredibile. Estremamente silenzioso, arriva completo di tutti materiali filtranti, ha l’uscita del flusso regolabile: - uscita dal basso - uscita centrale più distribuita - uscita dall’alto con valvola Venturi per l’ossigenazione (più rumorosa per via delle bollicine) Tutti i problemi di sporcizia nell’acqua si sono risolti nel giro di due giorni. In più la manutenzione sembra semplicissima in quanto il filtro è apribile dall’alto e i materiali sono facilmente estraibili. Consiglio a chiunque cerchi un filtro estremamente silenzioso ed efficace con un’ottima portata d’acqua senza necessariamente creare troppe correnti. Prezzo più che adeguato.

Just got this filter yesterday so cant say anything about longevity however so far so good! Please follow instructions carefully, I didnt remove the fan and run it under water which caused the fan to not work at first, however once I did that the filter worked great. I bought the filter for my turtle tank as a backup to my canister filter and it works great and turtle doesnt mind it. Also very quiet so far and very powerful!

Best in tank filter I’ve had. Bought as original tank filter went down in my 130l , the pros of this filter are - -super quite , hardly any noise -smart looking / blends in / fits nicely -3 different spray modes (top , bottom or middle for gentle flow) So easy to use / setup and for maintenance The water is really really clear with the active carbon in the filter , it comes with ceramic media too which is a bonus Overall really good filter , highly recommend this in tank instead of external canister
