The tank was cycled before he went in, so the water changes shouldn't have made a difference to the bacteria. Yah am changing over to bare bottom, I didn't realize how much axies pooped, was totally disgusting cleaning the sand off in my other axie tank. I can't see there being a problem with the set up, as Pendragon has the exact same set up as Morpheus, only differences are that Pendragon's sand is blue, Morpheus' is Purple, Pendragon has a glass tank, and Morpheus a plastic tank.
Bacteria congregates in the filter, barely 0.1% percent can be found on plants, glass or substrate, and total water changes will not make a difference to the bacteria colony as long as you keep the media under water at all times. Although I'm a novice with axies, I've kept fish for a long time, and understand basic water chemistry and whats required. The large water changes, I've used before with other amphibians and with fish and have always had fantastic results. My other axie Morpheus gets 75-90% water changes twice a week without a problem.
Okay just cleared the fridge out of dyes, Mum's pissed, since were virtually dumping $300 worth of quality dyes, we've stuffed as much as we can in the other fridge, but a lot is still going to have to be used in the next week or thrown out. The fridge doesn't say what temperature it is, and I couldn't find a thermometer anywhere that went that low, so I've just turned the temperature control up as far as it will go, and added in a couple of bottles of water for water changes,
How often should I be doing water changes? every day? every second day? and should I keep offering him food? or just leave him?
