(This got kinda long, Feel free to skip to the third paragraph for the meaty bits and questions.)
I have had my 20 gallon long tank up and running for about 5 months now. It is lit by a Finnex Stingray with a 7 hour photo period. Substrate is inert sand with Seachem root tabs. I have been following this
fertilizer schedule. I do a 25% water change every week.
According to aqadvisor I am at 108% capacity for livestock. Plants include a lot of crypts, a couple of anubis, one sword, a couple dozen java ferns, one aponogeton ulvaceus, one banana plant, three marimo moss balls, and a couple corkscrew vallisneria. This month I added one large wisteria plant, and about a dozen stems of bacopa.
Up until this month the fertilizers (here
) seems to be sufficient. I've been having issues with cyanobacteria for the past two weeks, and have been trying to get my nitrates up. I've been testing my nitrates every day. Every time I dose my fertilizers I get my nitrates up to about 15. The next day, they'll be close to five. By the second day after dosing, my nitrates will be basically zero. So this week I managed to keep them up by dozing every other day. This seems really excessive.
So my questions are, am I basically doing EI dosing now? Are the fertilizers I am using sufficient? Should I switch to something else?
Thanks for any suggestions or thoughts. Sorry this got so long. Thanks again.
