Well it’s been weeks since I changed water in my fish tanks and the turtle one started looking pretty scary although did not stink to bad it looked dirty. I usually drain my 29 gallon to 30% and the 45 gallon which is the turtle tank down to 20% and then use my Python Cleaner hose to add water back to both tanks. Anyone with a tank bigger then 30 gallons should get the Python cuz it makes it so much easier to change your water. The only problem I found while first using it is that if your sink is at the same or close to the same hight as your aquarium tank then it takes very long for the water to drain. My solution is to still drain the dirty water into a couple of buckets and then just use the Python to add water back in. The Python is basically a long clear hose with a gravel cleaner on one side for the aquarium and on the other side is an adaptor for your kitchen tap which allows the dirty water to be drained into your sink or feed fresh water back into your tank. Here is a link to a writeup on the internet about the Python.
My 20 gallon frog tank had 2 dead guppies and one dead frog. I knew this frog was gonna die soon cuz he has been getting skinnier and skinnier everyday while the other frogs look fat and yes I do feed my frogs. Now as far as the guppies I dunno why they died but I will check the PH tommorrow and see if that might be a reason. Having 5 tanks setup for a while now I have realized that out of all the fish that I have had so far the guppies are the least hardy fish of them all. I have lost a lot of them in the last few months and the water conditions such as temperture and PH have been pretty good. On the bright side one of my newest guppy females that I got a few weeks back had babies and I managed to save 5 of them and are now in a breeder tank inside the 20 gallon.
