FIL­TRA­TION

Practical Fishkeeping (UK) - - Fishkeeping Know How -

Fil­tra­tion needs to be on a large scale, tra­di­tion­ally 10% of the vol­ume, but mod­ern fil­tra­tion is more com­pact, such as fine mesh drum fil­ters com­pared to older fil­ters us­ing sponge. Ef­fi­cient au­to­mated sys­tems are costly, but older-style man­ual clean­ing sys­tems still give good re­sults and are com­par­a­tively in­ex­pen­sive.
