Something here isn´t right..or not matching. And you know i´m looking for answers for quite a while and i´m not on this hobby since yesterday.
This tank (i have another one) is suffering from this issue for almost a year now. (this brown algae)
Some issues we can put outside of the table such as:
Flow:
I can´t have anymore flow. If i push more i´m going to pick up the plants outside the tank and see the substrate flowing.
very good flow in the bottom, in the middle and upwards for aeration.
Co2:
It´s on 24 hours. And i´m not being changing a damn thing on it
it´s always giving 5 or 6 Bps or more (can´t count). I don´t do any testing cause i know tests aren´t reliable. I guide myself by the drop with 4dkh calibrated solution and it´s almost yellow. If the drop is a xit guide than i don´t know where from to guide for.
Lights:
I have twice 39W with 6500 K. If i turn lights to 78W Gsa imediately apeears no matter if i increase PO4 (cause remember i have good flow so this issue is outside the equation remaining the PO4) .
And it apears in such proportions you can´t imagine.. even doing three times water change per week and cleaning the glass she stills come back in a couple a days.. amazing!
If i return to 39W the tank doesn´t have ANY algae and Gsa disapear. But plants still presenting this little brown baby.
By the way it´s a 100 hundred liter tank
No matter what i do this brown algae is always present. Since the beggining.
So.. what´s remaining? The Fert and the filter media. The filter media was solved last week. But i dont´believe this was the cause has i have this since the beginning.
So, i rest my case for the fert.
I´m going to introduce MG and CA and we´ll see what hapens.
Then i will have a last issue to solve.. the 78W and gsa. Cause the tank with only 39W develops in slow motion..
If none of this events solve the tank i´m going to disassembling it and start a knew one with new ferts, and also FERTILE substrate. Cause today i know any tank must have this and not only the grain.
This was a mistake from the beggining and maybe the cause. Again.. Fert / nutrients.
I follow an advice and this was an error. Fertil substrate has carbon that is being realesed as Co2 ans this carbon is also being renovated in the fertil substrate.
I´m reaching a saturation point with this tank. It´s bieng quite desperate and unglorious of a fight.
I´m going to give it this last shot. If it doesn´t work out, bye bye. To much money on it.. it´s better to star all over.
Many thanks.
