Thread: 75 gal filtration
10-11-2012, 10:36 AM #21
Canister - all the way for efficent filtering, cleaner water and very, very quite operation; just can't be beat. This type of unit will cost somewhat more but well worth the extra dollars considering the cost of fish - also, these support in-line heaters which offer a few advantages (like always contain water even if you empty the tank.) Got a very nice canister unit with a UV system built in for under $100 - (someone here pointed out the unit) a bit over sized for my 75 but very nice unit. Would never go back to HOB or any other system. The amount of bio-chips these units can hold is amazing and since that is 125% of what you want/need for any filter, why use anything else? Just always fill with bio-media, never charcoal (except to remove meds but I have a stored HOB that I use for that purpose now.)
Now, if phosphates are an issue, then a HOB add-on unit would be worth the cost; such a unit could be a very low end since that is its only purpose - those phosphate absorbing additives get replaced fairly often and a canister would be a bear changing out; my unit needs a very minor cleaning every three months and even then, I get little debris.
I no longer bother with these additives now since I added an algae scrubber (or bubble falls unit as I call them.) These grow algae and this consumes phosphates nicely (as well nitrates! Even ammonia/nitrites and they only take a week to grow; but do need cleaning every week or two; otherwise, they lose their efficency.) Unless you build a large algae scrubber, this type of unit can't replace a real filtering system (I bought a fanastic small LED unit that fits in the tank by someone here who makes them - very nice price and good performance - send me a private e-mail if you want one - I hope I can still find their e-mail ... ugh. Also, I'll send you the site for the canister if you want one of those UV units.)
