Bing - From pond owners experience in northern midwest, reasonable amounts of aquashade (0.5 to 1ppm) will be removed by a couple steps of your treatment process.
1. chlorine will bleach it out, possibly chemically deteriote it. Check with Applied biochemists for verification.
2. Activated carbon filter will absorb most of the remaining organic residual from the acid blue and acid yellow dyes in aquashade.
3. Alum treatment may also have an impact on aquashade by absorbing some of the dyes. Ask Applied Biochemists for verification.
NOTE. Aquashade also contains an emulsifier and dispersing agent, monoethanolamine at less than 1%. This is not appproved by the US Food & Drug Admin. (FDA) as a food additive but it is allowed in as a pharmaceutic aid. I am pretty sure (Ask Applied Biochemists) that acid blue and acid yellow dyes are approved by FDA as food additives. EPA says you cannot use it in drinking water because it does not have a EPA registration permit. Check it out.
PS I would not drink water with aquashade, I would have my treatment system remove it so I did not have to drink it.
Another Note. No component in your water treatment system listed above has the ability to remove copper from the water, unless the whole house filter includes a reverse osmosis system (RO)or an ionic resin filter. Water treatment standards (EPA) do not allow water comsumption with copper levels above 1.3ppm.
Ohio EPA does not routinely allow municipalities to use Cutrine in reserviors for algae control because of its potentially long residual time in the water column.
