Hi Steve,
am very sorry, abit busy with work.
and my 480 litres tub have not reached me yet due to some delay over at China side, also recently purchase the fluval 207 for my 60 litres tank and remove the internal and hang on back filter, the canister filter is better, i should have purchase a canister filter in the first place..
some pics showing my res and fluval 207, loving it so much while waiting for my tub.
lastly, i have purchase the largest canister available, in this case is oase 850 and change the pre filter to 60ppi so i will be cleaning the pre filter weekly and in the main canister filter, maybe 2 or 3 month once.
waiting for my tub so i can assemble my oase canister filter 850
, will update some pics once my tub reaches me, hopefully by end of September or early October.
some pics below showing my oase biomaster 850..
