Before I invest in the Python Gravel Cleaner, the one that you hook directly to your faucet, and it also drains the old water into your sink. Is this a good investment? They look like they would be so much easier to use than a bucket and hauling water from the sink to the aquairum. What a messy job this can be. My question is treating the new water for
chlorine. When I do a
water change now, I always add the dechlorinator to the water before I add it to the tank. Would I put the dechlorinator directly into the tank as I was filling it, or is the Python cleaner not really recommended, because you can't treat the water before you add it to the tank? I hope I made sense.

If they can be used, are they any good? I sure would love to have one if they work the way they claim.
Thanks
