What tools are necessary for planting/maintaining a planted tank? What do you use and what could you not live without? All I use right now is scissors from trimming and a python to change water. I'm just curious to what other people have/use.
I really like to have a floating thermometer handy to check the temp of the water before I add it to the tank when doing a water change. I also have a small powerhead and a 200 watt titanium heater with a broken thermostat (it's stuck on) that I use to heat the water going into my tank. I have to use RO water and buffer it to the right KH and GH because of my tapwater quality, so that heater comes in handy as the RO is usually chilly after sitting in my car all day.
There are three or four medicine droppers hanging around my room as well. The graduated ones are great for dosing meds and I have two small glass ones for feeding frozen foods. They work really well for that purpose, especially when spot feeding certain fish.
Other than those, my "tools" include a few different buckets and a siphon hose... nothing too fancy.
I forgot to mention my white ice cube trays. I have five tanks running at home and check the parameters about once a week, so test tubes get to be a little time consuming. With my two trays, I can do four sets of tests at once (pH, KH, GH, NH4, NO2, NO3) and then recording the results is much easier as well. I keep track of everything I do to my tanks in a notebook. I know, a little OCD...
