Macros needed? And CSM+B instead of Flourish?

Okay, so my head is spinning from all the reading. Here is what my setup is going to be...

30 gallon tank (36x12x16)
4 10-15watt CFLs retrofitted into the hood
No CO2
Play sand substrate

10 Harlequin Rasbora
10 Corydoras
2 Bolivian Rams

Fish are first priority, but want to have good looking plants.

I have talked to people who only use root tabs and Flourish Comprehensive (1-2 times a week) and have great results. Is this because of low light/no CO2? Would I really need the macros?

And if I wanted to go DIY CSM+B is what I would use in place of Flourish Comp.? How much should I mix at a time? Thanks!

I can tell you that I have almost the same setup (29 g, 2x13 watt + 2x14 watt) and dosing macros helps ALOT. People say that you don't need it in lower light tanks, but if you don't have CO2 to control algae, the ferts are an invaluable tool. Especially with inert substrate.

I dose KH2PO4 3/64 tsp 2x/week and GH Boster 3/8 tsp 2x/week. I have a goldfish in this tank so I don't need to dose KNO3 but I would start at 3/16 tsp 2x/week. Buying dry ferts is also MUCH less expensive than buying premixed liquid ferts like Comprehensive.

You could use CSM+B instead of Gh Booster. I don't know why people bother premixing dry ferts into water unless they're dosing very small amounts (like a nano); it's just as easy to get a tiny set of measuring spoons and dump it straight in the tank.

Joy to the fishes!
