| Scott,
Glad to hear you're staying with the hobby, I always enjoy your posts.
As well as the increased O2, there's the potential for the gassing off of Ammonia, which then doesnt become Nitrite, then Nitrate. Perhaps at very low Nitrates, again there is less for the weed to feed off. Complicated scientific stuff which I havent the faintest about, but like you I'm just glad it's gone - at least for a while! LOL |
