Micro and Macro Nutrients

Is there a way/formula to tell how much Micro and Macro you need to keep in tank in balance so you dont get bba or any other type of algae?

How bad is it ? What do you currently dose ?

Here is my current view on the topic. Looking forward to see what other members have experienced.

The 'formula' or model would have too many factors besides the common micros and macros. Plus what you dose to the aquarium matters less than what actually is in the water. We cannot accurately/easily measure true real time water parameters. What is uptaken by the plants vs left in water depends on plant mix, density etc. Plant uptake is not linear to begin with (same plants won 't consume the same amount +x of nutrients on all the days) but as you can imagine the plant mass/demands are ever changing in one aquarium alone.

The fact that there are aquariums where both macros and micros are dosed in abundance and there is limited/no BBA suggests that there are other factors that significantly trigger/influence their growth. Estimative Index Dosing suggests that we dose all the plants need in excess and then deal with the rest of the factors ( organic load, light , flow etc). This approach provides a better environment for plant growth and a better mindset for you...focus on growing plants instead of fighting algae. I suggest you give this a reading: The Estimative Index of Dosing, or No Need for Test Kits - Aquarium Plants - Barr Report

Regarding BBA alone, I usually have problems with it when I have an increase in organic matter. If you want one point of failure I would look there. Some examples from my past experiences /mistakes that have lead to BBA: uncleaned filter, unvacuumed substrate, high fish stocking, overfeeding with live foods, unnoticed fish death, overgrown moss trapped debris, new wood still had some soft bark on it, troubles with CO2 leading too plant poor health. These are just observations not experiments but similar experiences have been repeated and reported by others.

Thanks for the response. I think based off your experience that my BBA problem stems from either Lack of co2 OR uncleaned filter. Ive got only 4 Otos and around 100 cherry shrimp in my 45G. It also has ada aquasoil so doesnt really need any vacuuming. I will try to clean the filter. Ive read that co2 doesnt solve bba problems so I dont want to go there yet since most of my plants are low light plants. I leave my light on in two 3 hr stints. 1-4 and then from 7-10. I dose seachem flourish once a week after a water change. So I dont know why my bba is spreading.

Well, more specifically the theory is that it is caused by inconsistent/ varying CO2 levels. I think these observations have some merit but the varying CO2 might affect many factors which can actually trigger the BBA growth. Lower CO2 means lower plant growth which means lower nutrient uptake. Lower CO2 also means that plants can start to hurt and leak organics in the water themselves. etc.

You are right in saying that CO2 does not solve ( as in remove ) BBA, even if lack of CO2 were the one point of failure. What starts a problem might not be necessary to maintain a problem. Conversely, if you take away what started the problem, it might not always lead to a solution for the problem. Therefore since you do not plant to go the CO2 route for the long term, I would not start.

The bioload is not much for a 45g. However, aquasoil can accumulate debris itself. I know aquasoil breaks itself down and by vacuuming you also pick that up, but small bits and pieces of detritus can also go through the cracks and accumulate there. How often /much do you change your water ?

You could try to use Seachem Excel to treat existing colonies. They will turn red /white when they die. This is a sure way to kill existing colonies but will not stop the spread.
