  1. Well that's very interesting in regard to the pH drop. I guess it makes sense that the CO2 might dissolve in the water and adjust the pH - I never thought of that. Perhaps I could just float a semi-submerged container with an entirely separate source of water. The warmth from the water insulating it would keep the "fog rolling," so to speak. If I did that, I guess all my other questions are negated, except the concern about breathing. After reading the post you linked, I see that people seemed very fearful about CO2, and more specifically, asphyxiation. That's very understandable, but given an outside location would this still be a realistic concern? We get about 10-20lbs of dry ice every year for Halloween, and I've never really been concerned with asphyxiation. It just seems like the conditions would have to be absolutely PRIME for dry ice to result in asphyxiation. Then again, maybe I'm being dumb!
  2. Haven't posted here in quite some time, but I have a rather odd question. For a spooky halloween effect, I thought it would be neet to put some dry ice in the tub. My questions are: Is this, in general, a good or bad idea (please explain why)? Is it possible that ease of breathing could become an issue? Do you think the spa will be able to maintain its temperature? How should the dry ice be placed within the tub (should there be containment)? Is there any way a tub could be damaged by this? How much dry ice do you think would be needed for a 350 gallon spa, and how long do you think it might last? Thanks in advance for everyones input. I'll have to post pictures if all goes well. Happy Halloween! Eric Kingston
  3. Wow, that's a long time to wait. I guess I can see why you might be so on edge! I'm sure all the little tasks in preperation of getting the tub will keep you busy though. Do you plan on running the electrical yourself? Eric
  4. Wow, that's incredibly odd. I hope it stays full and you don't have to call them back out. And if you do, I definitely wouldn't pay anymore service fees. Hope you start soaking soon! Eric P.S. Waterboy - Come on, are you being serious?? I have a pretty good feeling that John was, more than likely, not offended by those remarks. I think you need to either lighten up, or just get over yourself. Besides, it looks like the Polar Bear Club could be great fun!
  5. Well I'm no rocket scientist, but I'd say you have a leak somewhere for sure! For 300 gallons of water to just disappear within 2 hours, I think it would have had to spontaneously vaporize rather than merely evaporate. I hope you don't get any further problems from freezing while you wait until tomorrow. Good luck to you! Eric
  6. Oh yeah, forgot to mention: if you're really really cheap, you can just use a piece of paper with a really thick line of pencil lead (graphite) scribbled onto it and two alligator clips, one on each of the opposing ends. To adjust the resistance, simply slide the alligator clips closer or further together. I just figured I'd throw that out there, but seriously, spend $3.00 for a pot! Eric
  7. If you want a little more control, simply use a potentiometer in series with the thermistor (temperature probe). Get yourself a little digital cooking thermometer and a 5K pot, and you're good to go. I experimented with this a while back as a debugging tool, but since everything has been fixed, I no longer use it. 104 degrees is plenty for me! It's kinda fun, because you can watch the spas readout change temperatures as you adjust the pot. Keep in mind, you're only fooling the temperature gauge into thinking the water temperature is lower than it actually is. That's why you need the secondary thermometer, so you don't fool yourself as well. Have fun and don't hurt yourself, Eric P.S. Just to cover my own bum, I'd suggest not doing anything I said above! P.S.S. Here's what a potentiometer looks like for those who don't know:
  8. I just felt like offering a friendly hello from Michigan! Cheers, Eric
  9. No, It's not attached to the cover. Just flip the cover over, and as you lift it, the conduit guides it into position - off of the spa. The hardest part (for me anyway) was puting the cover back on. Now I just pull the cover back towards the spa, and the conduit lays it down into place, without binding against the wall or anything like that.
  10. My spa cover is embarrassingly old, ugly, waterlogged, and heavy. I don't have the extra cash to invest in a new one, so I decided to try and find a way to make life/coexistence with the old one a little bit easier. I've seen pictures of cover lifters, and they have never looked very complicated, so today I decided to attempt to build one. I took the approximate measurements I needed, and ran off to Home Creepo to get the items needed: 2 - 3/4" x 10' Conduit @ $3.97 ea. 2 - 90 Degree Conduit Elbows @ $3.62 ea. 2 - Lag Screws @ $0.95 ea. 4 - Washers @ $0.15 ea. I bent each end of one piece of conduit right there in the store at just under 90 degrees. When I got home, I cut the bent conduit in half, drilled a hole at the end of each bent piece, took the measurements I needed, and then made my final 3 cuts. I assembled the unit, then used the lag screws to attach the lifter at the base of my tub. It works perfectly! No more fuss for me - awesome!
  11. Isn't it great!? It's even better if your in it while the snow is falling! Cheers, Eric
  12. Open a photobucket account at www.photobucket.com Upload your image, then copy the Direct Link after the upload is finished. Click the "Insert Image" icon when making a post, and paste the link you copied in the box that pops up. Good luck, Eric
  13. The topic title states it all. I'm looking for a good way to get rid of snow and ice from my deck without harming the wood. Help! Any suggestions?? Eric
