Morning all,
I require some help on a tank I have now had set up for 5 months but with persistent hair algae and also poor plant health.. in particular Rotala rotundifolia stems.
First off here is some info on this setup..
ADA 90H - 90cm x45cm x 60cm around 230L
Light is a Twinstar 900s full power - Light on 14:00 - 21:00 - 7 Hours
Filter is Oase 250 thermo
CO2 reactor - Turns on at 07:30 - 20:00 - Drop checker is lime green at lights on
RO water re-minalised with Shrimp king GH +KH
Fertiliser - Masterline All in one
So ever since set up I have had issues with this one and I have tried a number of changes to try and get the balance better.
So this leads me to despair.. Please help - where do I go from here?!

So ever since set up I have had issues with this one and I have tried a number of changes to try and get the balance better.
- Started with Co2, had an in tank diffuser but decided the co2 was probably too low. I added a drop checker and it indicated a dark green colour. I swapped the in tank diffuser for the co2 reactor and up'd the bubble rate. I also added a second drop checker (one opposite side of the tank to the filter outlet around 8cm down from the water line and one on the back wall of the tank where the rotala growth problems were (Around 40cm down from the water surface).
- Next I added more flow. Although the surface movement from the lily pipes looked sufficient I added a powerhead to increase the flow around the tank - This didnt make any difference and if anything seemed to annoy my rummy nose tetras so I have now removed and gone back to use the filer flow.
- Then I changed the fertiliser routine. Maybe I wasn't feeding the plants enough?
Daily dosage Lots of light (>0.5 Watt per litre) + CO2
So I began with 8ML a day as recommended, as this was still producing poor growth I went with the train of thought that too much nutrients is better then not enough.. I started adding 25ML a day to see if the short term results were better... after two weeks.. no still poor growth.
Now I have stopped dosing for a few days to see if this helps..
According to Masterline -
(*1 ml per 30 litres = 1.20 mg/l NO3, 0.2 mg/l PO4, 1.6 mg/l K, 0.12 mg/l Mg, 0.09 mg/l Fe)1 ml per 30 litres*
