Been trying to temper my hoarding instinct, so I'd like to pass along some free stuff to people who may be able to use it. In general, please be a supporting member and plan to use what you take. First - a pair of wireless MP40 drivers. Changed them out with QD versions a little while back, and was planning to toss these. Any takers? AutoAqua Smart ATO. Almost 3 of them... But, one of the main units does not work very well, and I didn't label the bad one. There are probably 2 complete, working ATO's in this collection and you'll just need to experiment a little Soda Ash (sodium carbonate). I called BRS after placing the order that included this for another reason, and mentioned that this bag had torn and made a bit of a mess in the box, but didn't really lose that much. They sent me another bag for free. Now that I have my CaRX up and running, I don't need to use this regularly. Bought a big bag of sodium bicarbonate at costco, thinking it would be a good cheap way to dose alk. I opened it and used a little, but didn't end up going that way, plus I have a little of the BRS stuff too. Hydor internal skimmer. I used this on my original 18" cube tank, it worked well but is a little sensitive to water level. Dusty, but in great shape, ready to use for a small tank, but needs to be able to sit in at least 12" of water; will not work in a standard 10gal tank. Got this generic media reactor as a freebie as part of an order. It has not touched water, I just don't think I'll ever need it. Pickup at my place in SF/SOMA or possibly meet up at CFM next weekend (I'll be there early).
