Hi There,
Not sure if this post should sit in Algae or CO2 ? but here goes.
I have a planted tank, running for around 5 years, stats as below;
Tank specifications - 4ft x 19" x 15"/approx 45 gallons
Lighting - 2 x Arcadia T8's 42" 38w Arcadia Freshwater/Tropical - Photoperiod - 7hrs a day.
CO2 – D&D CO2 Set – on 2hrs before lights on and switched off 1hr before lights off
Filtration - 2 x Eheim 2224 - returning through spraybars & Hydor Koralia 1 for improved flow
Fertilisation routine – TPN+ every 2 days at 10ml, Flourish Excel dosed intermittently to try and eliminate the algae
Water Changes – Once a week with HMA filtered water
The problem I have is related to poor growth rate and algae forming on mostly one side of the tank, I'm pretty sure it's related to poor water flow and CO2 circulation. I've attached a picture (hopefully) of the tank setup with spraybars and korali location, what I find is that growth is faster on the right hand side of the tank where the CO2 comes in, against the left hand side of the tank where growth is slower and I have algae forming. I'm looking for some advice on the best placement for the spraybars, koralia and diffuser as I'm struggling to get good CO2 circulation, at present I have the diffuser sited under one of the eheim inlet pipes, so it travels through the filter and is fed out the spray bar, I’m not sure if this is the best method for a tank this size ? I’m also struggling with algae forming on the plants, it looks like hair algae and nothing I do seems to prevent it forming on the plants.
Any advice would be great……
