I'm interested to hear opinions here: to vacuum or not?
If a planted aquarium has decent flow and filtration with sufficient water changes do we need to vacuum the bottom?
Just wondering whether livestock needs to be taken into account?
If you have Corys are you better off removing as much detritus as possible??
As well as MTS, Red Ramshorn and Physella snails, I have Asellus in the tanks, and they are extremely efficient at removing plant detritus, to the extent that the only mulm I get are small black flecks of (presumably) inedible material.Detritus is not per definition a bad thing, snails and shrimp and also some fish eat off it, they help to break it down and are a link in the process to turn it into plant fertilization. For some snails it even is essential, for example Viviparidae snails are highly depended on detritus, they feed like little vacuum cleaners filtering eddible particles out of the water from the detritus.
I think this answer is for planted tanks.If it's not to daft a question, does the same answers apply to tanks with gravel substrates?
I have a number of tanks with fancy goldfish and all of them have a gravel base leaving bigger gaps for waste to fall into. The fish do dig around in the gravel but I'm wondering if hoovering over the top as with a sand substrate still applies to gravel.
