Here is my current setup with an Eclipse System 12. I will be upgrading to a 29 within a month and a 75 within a year

1 baby 2.5 month Swordtail
3 Bronze Corydoras
5 White Cloud Golden Minnows

2 Water Wisteria
1 Wendetti Crypt
2 ? Crypts (long lance rusty leaves - reddish under)
1 Dark fern unknown

Well Water Tap: pH 6.6 - GH 80 - KH under 40 - No Nitrates or Chlorine/Chloramine

In Tank: Temp 76-77 pH 7.0 - GH 120 - KH 120 - (using baking soda 1/2 tsp per water change to raise KH) 0 ammonia, 0 nitrites, 15-20
nitrates

Water Changes with gravel vac 50% weekly
Water Changes 50% when nitrates raise above 20

Thank you. Yes I plan on getting the 29 ASAP. We are planning our next trip to Anchorage which is 100 miles away. It will not be a "kit" as I want to pick out my own lights. So I will be ordering all but the tank online.

I am currently stuck on the filter - XP2 Filstar, Magnum 350 Pro or Emperer 400. I want the 55 watt All-Glass High Output Strip light with the All-Glass versa top. I also plan to use eco-complete planted substrate and include a sand beach for my cory cats.

Yes, I am excited
