I have a 46g planted bow front high tech tank. Below is my current setup with comments.
1)Light: Coralife Aqualight 2x96w 10,000k bulbs. I run one bulb for 10 hours, and the other only 6. 192w is a bit much for a 46g tank, so that's why I do partial light for some of the day. Overall, this is a good fixture for this tank. Ahsupply.com also has a nice retrofit kit if you want to put it in a hood. If you already have a hood, installation of the ahsuppy kit takes about 30 minutes.
2)Filter: I have an Eheim 2128. It's overkill. I would recommend Eheim 2026(or 2126 with integrated heater) or Rena XP3. Cannister filter only, no HOB.
3)Heater: I have the Eheim 2128 with integrated heater, works well. Either an integrated heater in your filter like the Eheim 2126 or get a Hydor Inline heater 300w. It's nice not having a heater in the tank.
4)Substrate: I use 50/50 Seachem Flourite/Soilmaster Select. If I were doing it again, I would go 100% ADA Aquasoil. ADA recommends the use of powersand underneath the Aquasoil...I wouldn't do this, I would do 100% Aquasoil. Aquasoil releases ammonia so it requires about a 2 week cycle. Aquasoil grows the best plants, hands down, no discussion.
5)CO2: Pressurized 10-20# cylinder. You can get a good price on an empty cyilnder from beveragefactory.com or you can look locally. Typically, you can find somethingi cheaper and filled locally. Milwaukee Regulator with integrated bubble counter/needle valve/ and solenoid. Ebay is a good place for the regulator. Milwaukee pH controller, I have it, it's not required but nice. I run my co2 line directly into the intake of my cannister filter. Dissolves well.
7) I do diy fertilizers from
www.aquariumfertilizer.com, cheap and easy.
8)Get a drop checker off of ebay for measuring co2.
For setting up a tank, research EI Dosing. Also, read everything you can about all types of algae.
Plant heavy with fast growing stem plants in the beginning, and then later on switch out if you want. This will help you adjust to high light, high co2, high nutrient levels and it'll be more forgiving(regarding algae outbreaks).
Algae happens. Amano shirmp, Siamese Algae Eaters, Nerite Snails, and Oto's really help. In tanks 46g and large it's easy to keep all of these at once. Conventional Wisdom is that Nerites don't do so well in co2 induced tanks but I know people that keep them with no problem. I'm recieving my first nerites today, so I'll see how they do in my pH 6.4 tank.
If you have any questions, feel free to ask. Searching this forum can also be great for quick, perhaps more in depth answers.
