Head smells- where is my in-line dispenser?

Years ago I used to buy a little bottle of blue liquid that would enter the bowl with each pump. I've checked and can not find it anywhere. Doing some research on line I found Sea Smart Marine which monitors the bay water coming into the head and dispenses the correct amount to sanitize the entire entry hose. It is self contained, battery monitoring system from the UK for about 160 pounds. Has anyone found the old small bottle that fit into the hose between the pump and bowl or used this Sea Smart Marine deodorizer or something else. I read a few posts about putting liquid into the bowl, but one of my partners is particularly sensitive to smell. (I've already done the H34 false bilge rebuild with eliminated all the water under the false bottom and eliminated the gallons of awful smelling liquid that built up over 30+ years.)

Do you have a picture?

Also, as Mr. Fox pointed out, there are many good additives that can be diluted ~ 10x and put into a spray bottle. I like Forespar Refresh. It also smells and functions a bit like Febreeze, and given the small size of the typical head compartment, this is not a bad thing. Once I explained it, guests really liked the idea.

There's a MUCH better solution to sea water odor from the toilet intake than inline chemical cartridges...which not only can get expensive if you have to replace 'em very often, but are usually messy to replace.
The simplest solution:
Sink drain thru-hulls are below the waterline on almost all sailboats. So re-route the toilet intake hose to tee or wye it into the sink drain line as close to the seacock as possible because the connection must be below waterline to work.
This will allow you to flush normally with sea water. After you’ve closed the sink drain seacock in preparation to close up the boat (you do close all seacocks before leaving the boat to sit??), fill the sink with clean fresh water and flush the toilet. Because the seacock is closed, the toilet will draw the water out of the sink, rinsing the sea water out of the entire system—intake line, pump, channel in the rim of the bowl and the discharge line,(Water poured into the bowl only rinses out the toilet discharge line). If your toilet is electric, be careful not to let it run dry…doing so can burn out the intake impeller. Or you can keep the sink drain seacock closed except when it's needed to drain the sink and flush with fresh water down the sink all the time...your choice.

It may also be necessary to keep the sink plugged except when in use, with a rubber sink plug or by installing a conveniently located shut-off valve in the drain hose. Otherwise the toilet may pull air through the sink when you try to flush, preventing the pump from priming.
Total cost: < $10 for the tee.
