CO2 scrubber info - Soda Lime over sump water bad?

[Projects with Sam]

Hi,
I have developed and am selling a recirculating CO2 scrubber that saves space and setup time but I have a concern about people having soda lime over their sumps. I am wondering if flakes of the soda lime falling into the sump would be bad for the tanks inhabitants.

The CO2 scrubber is here: its basically a Skimmer lid basket that recaptures the air to feed back into the skimmer.

Skimmer CO2 Scrubber Cap

3D printed skimmer cap to hold bags of soda lime to reduce CO2 in the skimmer air intake. The top cap has two 6.5mm O.D. tubes protruding from the rim. These tubes should be attached to the skimmer air input. If your skimmer is not listed, contact me and I can add it. This is still in...

I'll be posting install videos and more information soon. My prototype MKIII is ready... (photos are the MKI)

If flakes are falling in, the concerns are pH and alk boosts (small possible calcium boost), and any impurities that may be in it.

Installed and ran it. It overflowed and didnt cause too much of a fuss. my weep holes weren't big enough so water was pulled through the media and some overflowed into the sump. There was a Ph spike but not too bad and my Alk didn't change much.
Dialed back my skimmer a bit and its been running great. Because its recirculating I don't get any bad smells either.
