Wholly Mackerel
This thread just gets better and better
I'm gonna stick my neck out here and put in my 10 cents
I haven't touched my sandbed for over 6 months and don't plan to do so anytime soon
If your sand gets mucked up, siphon some of it out and be done with it, but keep your removal to the 1/8" level
If it's clean, leave it alone
Why remove all the critters ?
Don't siphon into dsb's past the 1/4" level and risk exposing hydrogen sulphide
Maybe my measurements are a bit off, so do your own research
I'd add more, but I'll bite my tongue
