Sumps have been used in high tech planted tanks injected with co2
. I believe Tom Barr uses them. Even if you started with just 4 plants, you might want to expand until you eventually transition to SW
. So in other words, you say 4 plants now...but who knows?
It can be looked at in a simple progression that some take... something like this: start off with FW
fish-only w/ plastic plants, then to low tech planted, then high tech with possible 'Collectoritis' tendencies (like me)..then move to SW FOWLR
, and finally to the reef (the real money pit). Some folks just jump right in to the hard stuff, but that's of course up to you and your willingness to research with possible deep pockets? But the longer you stay in the planted tank side it's quite possible you might catch "the bug" and want to stay a little longer before moving on to SW
. With that said, here's something interesting to read:
Plantbrain's "Stages of the Aquascaper"
So back to the business if the sump, which I'm assuming you want to eventually move to SW
, right? Just by performing a quick internet search, there are some examples of how to mod your sump to not off gas co2
, that is if you ever get involved with pressurized CO2
in the first place.
