The only problem I see from introducing a steady, but low level of ammonia is possible algae blooms being triggered. But, since this would not be a fluctuating input the algae spores might not chose to "hatch".
Seachem doesn't seem too enthralled with my idea for dosing a holding container with a big overdose of Prime, then letting that get diluted as the change water cycles thru the holding container. I understand their concerns, so I probably will go with a filter of some kind instead. However I don't want to have to spend $300 for the filter and $100 each for monthly filter element replacements, so I really want to visit my local Ace Hardware and find something that fits my bank account better.
This is part of the fun of DIY though - the design decision process! |
There are some cartridge units for ice makers that just screw inline, that may be a place to start. just set up a slow flow and test for chloramine. there was a Hach test kit mentioned in the second article but I didn't look it up figuring it would be spendy. Maybe there is a less expensive kit available somewhere.
(EDIT) It's not as bad as I thought it's $60.00 + shipping.
