I purchased a 2nd hand 305 with media. Filled my tank 72 hours ago, wanted to give the old media a chance to boost my cycling and bacteria, began using the filter and used media 72 hours ago also.
After a vist to my LFS today he said rip the media out, as after it has been out of water for 6 hours, it's dead (filter was out of water 24 hours).
Luckily I had a fluval extra value pack, which I mistakenly thought contained everything for my filter! I got home today to open my filter to find a foam filter which I thought was the "polishing pad" on the left (sorry I was dumb), this is obviously a filter not a polishing pad.
I was going to get new filter pads (x4) tomorrow and put in tomorrow. I gave them a clean (in tank water) tonight and put them back in, but I figure I should start with new filter pads.
Where I am confused the trays had the following in,which I couldn't see as a standard fluval 305 setup:
Top tray: small pea sized balls
Middle tray: cylindrical tubes
Bottom tray: cylindrical tubes
I now have put in:
Top tray: polishing pads (one either side of the tray, but looks like I could fit x2 in easy, so 4 in total In the top tray)
Middle tray: ammonia remover
Bottom tray: cylindrical tubes that were in there previously
Didn't use any of the carbon in as wasn't sure exactly which order to put things in! Can't figure out if the cylindrical tubes were biomax or pre filter.
- the fluval instructions that were I the box with the water polishing pads reads "place the pad in the last chamber, below the bio max basket" is this a typo??
- is my media tray selection ok? Should I replace the cylindrical tubes in the bottom tray with news ones?
- as I am fairly early onion the cycling stage, should I replace all 4 filter pads (not polishing pads) tomorrow
- should I use the carbon that came with extra value pack?
Complete confused by this as on the side of the fluval extra value pack I have it reads:
Suggested media placement:
-water polishing pad
No where does it refer to bio max or pre-filter.
Thanks in advance
