[gaston]

1st I have read Peggys Bible
2nd I have tried Noliflex but the stink comes back $45 a bottle in Australia
3 I have flushed the 100liter tank and inspected there is no build up
4 Im in brackish water ?
5 I have fitted carbon filter
6 Is Sodium Percarbonate the answer
7 Im fed up
8 Should I change diet

But seriously, first time we didn’t stink was when we went to fresh water flush. Never looked back.

If you have read Peggy's book you should already know the chemical answer is OXYGEN... O2... If you don't have enpugh it will STINK.

I ended up adding a bubbler and it has worked wonders.

You could try rerouting your vent to the highest point on your boat. that would at least get the odor away from you.

Good thought but we near live on the flybridge so best keep the stink away from up there .And I dont think all the stink is from the breather

Not to be confused with the Todd Carney kind of bubbler.

Yes fresh may be the answer but I dont want to go to that extent yet.

Second on the oxygen. We had a previous boat that had a horrible smell outside at the vent every time we flushed the heads. We installed a Groco Sweetank and in 2 hours the smell went away and we never put any chemicals in the holding tank again. Never had any more problems with the venting smell. If you have a charcoal filter in the vent line, it will inhibit the oxygen flow in and out of the tank and make the problem worse. Ideally you wold have 2 vents, one on each side of the boat to let air flow through the tank. If not try a Sweettank to introduce oxygen into the tank.

The carbon filter may be inhibiting oxygen flow.

FWIW, we use Noflex now (KO, before) -- mostly just to head off sludge build-up -- but we actually had no odor before using either, nor after using those products. OTOH, ours is fresh water flush.

Put a couple of new vents in. You want 1 inch vent lines to get a good air flow.
The vent lines on most all boats are way to small.

400 litre black tank onboard and two years on the hook.
1 inch vent is all there is.
Only time we notice a smell is when we pump out.
Fresh water flush toilets.

Some good ideas introducing oxygen is a winter project but Im still looking for a chemical answer to black water tank? ??????????

[MERIDIAN 2]

Oxyclean???? (laundry additive)

I guess we do not understand what you are asking... What exactly are you looking for?

Third on the oxygen!!
On a previous boat, by running two 1" vent lines to opposite sides of the boat, there was good cross ventilation and the stink was gone.
