Is there a way you can reduce the intensity of your lighting? I have had good success with reducing lighting levels and manual removal.
How often are you changing water? And how much?I could reduce one of the 2 but with my tank being 24” deep and about 18” to my substrate I need the high par level for my Monte Carlo that I’m trying to carpet and light hungry plants. I don’t think I can reduce intensity and keep my par levels.
Water changes every Saturday and about 30 % so I don’t shock my shrimp to much. I have only had one light on and had it raised but the carpet and red plants weren't doing good because my tank is already 24” deep so I would be adding 4” more of height.How often are you changing water? And how much?
Keep dosing your ferts, algae pops up because lighting, co2, nutrients are out of balance, I suspect the lighting.
I would start with reducing your light intensity. Have you run your tank with just the Twinstar? Raising the light off of the tank will increase light spread and reduce PAR at substrate. Raise the lights and monitor your monte carlo.
I have the same problem. I got some rotala red from someone else's tank that had hair algae on it thinking no problem my mollies will eat it. Nope. Now its everywhere.I doubt it is a lighting issue. I use a home built LED fixture on my 120 gallon and had everything in balance for roughly 3 years without a hair algea issue. Then I got some new Anabas plants and saw some hair algae on them about a month after planting them. It spread like wild fire for me and now I'm even considering a complete rebuild of the tank to get rid of it.
The Anabas is one of my favorite foreground plant and the hair algae started at its roots.
What auto doser do you use and also what ferts do you use?When I fight algae there's three things to do:
1. Ease up on the light brightness
2. Increase co2 and macro ferts
3. Spend some time manually cleaning things (plants, filter, substrate) several different times
You sound like you've got a good handle on this though. The thing to try is less light intensity, duration seems fine. Monte Carlo doesn't need as much light to carpet as you might think. It'll be a bad carpet if it's covered with algae.
My tanks do a lot better with auto dosing pumps. Im too inconsistent at fertilizing manually. Algae takes advantage of my inconsistency.
