I'm a huge fan of Filstar XP series. Currently running a couple of XP1's on smaller tanks. Running a pair of XP's, dependant on what size tank I decide on was my first option. I was just curious if theres better option's on big tanks. So far a pair of canisters seem to be most reliable. As Brian said, you can alternate cleaning, which is very important in keeping a sustainable amount of bacteria. Plus, if one filter fails for some reason. You still have one filter working. Albeit one filter running in a big tank would be overworked, but atleast water would continue to be turned over.
I know what you mean about bioload Brian. Currently I have a heavily planted 40g with three Discuss 4" in size. I set this tank up as a trial, seeing how these were my first Discus. Needless to say, I'm hooked. err bad pun
Anyway, I currenctly have an XP1 with a pre filter on the intake. I'm doing 25% WC
's every 2 or 3 days. The prefilter gets cleaned every WC
. I also have a powedhead with a course filter attached to help move more water. I clean the powerhead filter every WC
as well. Thankfully this set up allows me to get by with cleaning the XP canister every couple of weeks.
Also Brian, you ever run a diatom in your 125g or is routine care enough?
Thank you all for the comments. I'm still open for suggestions.
It will be 3 or 4 months before I actually have a big tank up and running. At this point, Im trying to research as much as posssible before I start laying down hard earned cash.
