Best thing I ever did was buy a proper cylinder with reg and solenoid, saved time, effort and $ wasting time trying to cut corners and I achieved exactly what you want. Set and forget for 6 - 8 months.
In that case you have 2 options
1) Strip and have Cyp fry or
2) Let them spit and have fat Comps
I had a colony Mpulungu that I kept purely to use as Alto food
Custom FTW - You'll learn a lot on the way. Not to mention its exactly how you want it.
Donny - There is only space 1 marine so donate the Cade to me (Ben said its ok)
@Shon I used NLS for awhile as well as the Ocean Nutrition Flakes and it is good stuff, fish loved it, but I found that soaking it first helped.
Ben has never said no to a price match to me, with some of them I felt guilty to ask, but he has always done his best. Like Donny said, doesnt harm to ask
