It is planted, I have about 4 varities of plant in there (with a lot of ludwiga). It is a 180 litre Juwel Vision. Nitrates currently are at 60ppm, ammonia 0, nitrites 0, PH 6.6-6.8. GH around 16, KH between 3 and 6. Bit colourblind so was hard to tell on the KH!
Stocked with the following;
13 tiger barbs
7 bristlenose catfish
2 Apistogramma Agassizi
4 dwarf neon rainbowfish
3 yoyo loaches
(the 7 bristlenose are juvies, and am giving away 4 of these after identifying 2m 1f)
I have ludwiga repens (quite a bit), Myriophyllum scabratum (looking a bit dull on the lower branches/leaves), Vallisneria Gigantea Java, Anubias Coffeefolia. Am awaiting a delivery arriving tomorrow of 5 other plants to add to these. (also have another foreground plant that I haven't identified just yet, that has dark leaves as they get older, that get replaced by greener leaves and propogates by a runner underneath the substrate sort of making a sister plant)
Substrate is flourite black, two pieces of reasonably sized bogwood. Eheim 2215 with spray bar, and Eheim Liberty 2014 (I think). DIY co2 goes through the intake to the Liberty and back out into the tank... diffuses quite well as can see fine bubbles flowing into the tank.
I haven't actually done any readings or got any test kits for co2, so that's why I'm not exactly sure of how much is going into the tank tbh.
Had to throw away some java fern as it started to get hair algae on it and diatoms (but think they were eggs!

), and when I cleaned it, it sort of fell apart and I got annoyed with it so threw it all away. Lovely leaves they were and managed to attach them to the bogwood on one side of the tank. Shame, but ah well there is always another time I suppose.
The algae problem started with GSA... which I promptly removed, and used a syphon to clean it from the gravel at the same time and then did a water change. My tank is looking a bit better at the moment, and all I did was use Kordon Amquel Plus - which is odd that it improved the situation really so didn't narrow down the actual issue.
I took plants out this morning, and used my algae scraper to softly brush the leaves and removed some hair algae (it wasn't loads but was still noticeable when getting close to the tank).
I used to run at 27 degrees C, but I run at 24-25 degrees C at the moment. To be fair when it was running 27, because of central heating it fluctuated a bit day to night and wasn't exactly regular. But at the moment temp is regular 24-25.
I also threw away some old food that I had, as I had read some food that is a few months old is not good for fish or water quality and have also started feeding very small amount for two times a day, and placing some sinking wafers near to where my bottom feeders go.
I have also JBL KugeIn balls within the substate, about 6 in total located close to the clumps of plants for root nutrients.
2x 35 watt T5 lights. One Day lite at the back, one nature at the front.
Hope that extra info helps!
EDIT: I add the recommended dosage of EasyLife profito once a week. But only just added the easy carb today so that might also have helped? Also T5 bulbs are only 1 month old.
Another thing I changed that probably helped was I had taken an old T5 daylite that I had, and it was on the T5 unit... I put a new nature light on there instead. Not sure why I decided an old T5 daylite was better than a new nature light to be honest but yeah something else that changed this morning.
Looks similar to that. Except the boesemani's went back to the LFS. =( but yeah most of it looks the same minus the java on the left bogwood now gone.
