186ltr tank (150ltr water) (100cm long)
1400lph external filter
Spraybar along full length of back of tank pointed forward.
2x 39W t5's, 7hours
Mostly pretty easy to grow plants anubias, java ferns, mosses, + HC
BBA & Staghorn issues - due to lack of flow I'm reckoning.
Liquid ferts added (2ml daily) (TPN+)
Easycarbo added (5ml daily)

I will be getting either 2x tunze 6015 powerheads (1800lph) or 1x 6025 (2500lph).

Where is the best place to position them / it?

I'm thinking on the back pointing forward to match the exisitng flow (one centrally, or one at 25cm & one at 75cm). Or one mounted on each side, pointed diagonally forward towards the front.

What do you think?
