i've used an undergravel filter on every aquarium i've ever done. just picked up a sun sun 302 plus media for 50 bucks and free shipping.
i'm on an almost 10 year break from fish. when my tiger oscars, i raised from barely an inch, died i lost my interest. they were a week from getting a much bigger tank. but i want to do a tank again.
a few weeks ago i set up a 30 with an ugf
to do some fish then i got a free 55 gallon. so my lady will get the 30 and i'm going to do a cichlid tank in the 55.
i bought a sun sun 302 canister for the bigger tank since i want to do a sandy substrate and i have questions. it is my first go at a canister.
it is up and running in the 30 along side the ugf
to help establish the media. it came with a bag (10 oz i think) of ceramic rings and a bag of some short skinny black spaghetti looking things that i don't know what they are. i think since its black it is carbon but i don't know.
i have it ordered how it was shipped to me. on the bottom tray is the bag of ceramic rings and the white pad on top. middle tray is empty with just a white pad in it. top tray has the black noodle things with the white pad on top. i'm not sure if the white pads should be underneath the media or on top of it.
i know i need more media. i went to buy some on ebay but then i thought i'd better ask before i bought the wrong stuff or too much. it looks like i could get two bags of the ceramic rings in each tray. so if i bought another 1000 grams of ceramic rings for two trays and then got some bio foam or whatever for the third is this a good setup. is a two pack of the bio foam enough for one tray. and again i don't know how to order it in the canister.
