Good analogy, but how do I counter Dinos, I assume they came due to low to no nutrients. Whats confusing for me is I have algae scrubber working and it has quite a lot GHA in it, so what prompted Dinos, when it had its competitor consuming nutrients.
Is it due to very low nutrients, that is not utilised by GHA as efficiently as Dinos? Meaning I need to increase my nutrients so GHA gets a short.
In the past I countered dinos by reducing light and bunping the tempreture to 28-29 Celsius, but I can't risk this now as I have livestock.
So would love to hear what you guys think.
I think you should do a few things that will help out.
1) Reduce the time on your scrubber to only 8 hours and actually increase your skimming on the skimmer to a very wet skim which you need to empty out every day. (You will want to compensate for the reactor being off and will help to pull any gunk out of the water that you dislodge)
2) Increase flow if you can.
3) Manual removal of the "brown algae" on your rocks by siphoning directly from the rock AND then turkey basting the rockwork. (This will only benefit you if you are using filter socks/ fleece which will filter the water. I suggest cleaning them every day if you can)
4) Slowly increase feeding or manually dose small amounts of nitrate until you have detectable levels. Doesnt need to be high but slight pink is fine on your test kit.
Once you get the "brown algae" under control then you can focus more on the input/output side of things.
