Hi:

We have had our redwood hot tub for 15 years. About 6 months ago it started getting "slippery" or "furry" on the sides and under the seats. After stiff brushing and a water change I cleaned out the filter. What I cleaned out was wood fibers. Enough to make a large soft ball. Other symptoms include: (1) losing wood between the red wood boards that make up the seats (I can see the dowels) and (2) the jets are now about 1/8" past the side wall of the tub - looks like the wood up and left.

Normal care and feeding:
[*]Using test strips for chloride and ph - adjust once a week
[*]Filter cleaned after psi change in filter as marked on pressure cap


Current open issues:
1. Air leak in air supply hose to jets
2. Water leak around pvc hose feeding jets (about 0.5" week)

Maintenance in 15 years:
Replaced filter media three times
Replaced moter once
Replaced filter canister
Removed seats, planed them, put then back in.

What can I do to shave the beard and stop the wood from leaving the hot tub?

You're using WAYYYYYYYYYYYYYYYyyyyyyyyyyyyyyyyyyyyyyyyyyy too much chlorine (or putting in too much with each application), and it's breaking down and deteriorating the wood.
