@mulm- Let's Talk @ argnom- Yeah I Like PP A Lot
Hi,
Then by all means use the Tygon product, I have always been happy with Tygon products.
The problem I see is that sooner or later these hoses will gunk up as well. :gw
I think somewhere along the way you are going to need to address the flow issue. I do not know what you are using for pumps or filters but a few possibilities leap to mind:
- lack of oomph (technical term) from a pump

- obstruction(s)
- more gunk (another technical term) coming in than your system can handle
- a design flaw
- some combination of the above
- a conspiracy of inter-galactic proportions

Before spending money on expensive tubing that may or may not solve the problem, why not talk about your system?
@ argnom- It is not that I think potassium permanganates, KMnO4 (PP) are perfect for every situation, I do think it is one of the best overall, consistently effective treatments available and it is cheap! I use 35% H2O2 as well though it has a couple of drawbacks and not the overall efficacy of PP.
