20 gallon high( 24"Lx12"Wx16"H)
AquaClear 30: 1 sponge, 2 biomax. Do you think I need to run a carbon?
50watt submersible heater
24" strip light
Digital or glass thermometer
1" fine sandbed or Flourite substrate( Will use from my planted tank I took down)
Various rocks and a few plastic plants
Here are the questions I have:
1.) Tap water + Water dechlorinator + Marine salt = Brackish water correct?
2.) How many Figure Eight puffers could I keep in a 20g high? and can I keep tankmates with the puffer such as bumblebee gobies, or Knight Gobies?
3.) What Specific Gravity should I aim for?
4.) What are a variety of foods that I can feed Figure Eight puffer?
5.) Should I use a Freshwater test kit or saltwater test kit? or does it really matter.
6.) Is a water change for a brackish tank similar to a saltwater tanks? like take tap water, add dechlorinator, marine salt, and mix for 24hrs then test SG before adding to the tank?
7.) Would a AquaClear 30 be enough filtration for a 20g high?
Sorry for all the questions but I would like to set the tank up correctly, and know how to care for the puffer.
