Algae and water hardness *help!*
Still in my first year of planted tanks but feel like I've been through a lot.
I'm in Arizona..Phoenix to be exact.
The water here is crazy hard and I've read here on this forum that most who live here get an RO unit. Then they add whatever to reach ideal levels.
I understand this concept. I also understand that there are hard water plants and soft water plants.
I do not have an RO unit, nor do I purchase distilled water. I use my Brita filter and that is it. So my water remains very hard even though its been filtered.
My issue is I keep getting algae. Hair algae, brown algae.
Can someone who is familiar with hard water where they live give me advice?
Here is my routine.
I have pressurized CO2 at a consistent rate about 3 bps which as main source of algae related issues, I don't feel is the culprit.
I have a current freshwater + led on for 7 hrs per day as my light source.
It's 10 gallon..I have my hob AND powerhead turned up so flow is good.
I had a bunch of glosso and stargrass originally but had to tear it out and replanted with dwarf hair grass and couple other different plants..but the hair algae comes back as well as brown algae on glass.
I feel like it has to be my ferts.
I dose EI via all Seachem products as listed via chart on their website. (Yes I know I'm wasting $ but I'll order dry when I'm out of these)
I guess my question, without phosphate tests or other "extra" tests (I have API Master and GH & KH)...
...is there a general rule of thumb when it comes to hard water that may help me? Like do they require less or more phosphorus, nitrogen, trace, potassium, etc...basically all the products I'm using from Seachem line..and you can look at the chart they have on their site that details EI via their line which I follow to the T....am I possibly over or underdosing one or more being that my water is off the charts hard?
