Hi guys, I converted my reef tank with sump to Freshwater. There are lots of pros with it but I'm finding some cons to, mainly related to co2.
PROS:
1) Zero film on surface, the overflow takes care of it.
2) Sump hides all my heaters, media, filters, reactors, sponges etc
3) water change from the sump instead of DT
BUT...
I'm finding there is too much gassing off due to the way the reef tanks with sumps are designed, too much turbulent water. My DC return pump is already set to the lowest setting.
My drop checker only goes from blue to light blue only.
I had my diffuser placed in the usual position inside the display tank (on right side) but I could see the micro bubbles float then follow the current go down the overflow and into the sump, where I am assuming its gassed off. Not much of the bubbles reached the left side. I increased the co2 but the tank ended up like 'fizzy bubble show'
I'm trying something different now with the Diffuser in the sump placed right next to the Return pump. I was hoping the Return pump would act like a co2 reactor pulling in the bubbles and 'chopping' it smaller and hoping the gas will dissolve as it returns to the display.
Results are only slightly better, finer bubbles which reaches both sides of the tank but they still float up quite quickly since the flow setting is at its lowest.
Recommendation on how I can improve the dissolve rate? less gassing? more efficient use of co2?
