Bit lost, Algae and Plant Problems
Rather new to planted tanks and aquariums in general, but have learnt a lot lately! I have set up a small 45l low tech planted tank and I am running into some problems.
The first 4-6 weeks went well, plants were looking good, and only a small amount of algae, few plants melted due to being grown emerged. But these are coming back.
But the last 8-12 weeks the tank has been getting worse. I think hair algae has started going onto plants, rock and wood. Some small black spots are coming on my anubius and amazon swords. Holes in some bacopa and hydrophilic. Even my frogbit is having having some leaves dye off, yellow or holes in them.
So I am running a 45l, with a Seachem Tidal 34 HOB filter, with the sponge and 100ml matrix that came with it. (I did put purigen in for a bit, but it seemed to strip the nitrates back way too much, 5-10ppm. So that is out at the moment, as it seems to have gone downhill since that went in. ) Should I have more matrix in there, definitely room for a bit more?
Lights are on for 7 hours, slowly dropped down from 9 when I started it, have just lowered the brightness to try to stop the algae at the moment. This is a Nicrew LED light.
The substrate is the Tropica soil.
Water parameters are, 0 Ammonia, 0 Nitrites, and 20-40 ppm Nitrates. Have just started using the Tropica specialised first, which went a brought the nitrates up a bit to much, so doing a WC as we speak to bring it down to more the 20ppm.
Live stock, 5 danio fish, 4 ammano shrimp and one nerite snail.
I am bit lost as to what to try next, and why it went downhill so fast. Maybe from not dosing to regularly at the start?
Would love to hear your thoughts and suggestions.
Thanks in advance,
