KentFishFanUK Posted August 4, 2021 Share Posted August 4, 2021 Ok so I know algae problems etc have been done to death but I can't wrap my head around it or figure out my best solution for my 20 gallon community tank. I am playing around with adding more fertilizer and more plants etc in the hope I can get the tank nice and balanced. My light is on quite a while but it's only the starter light that comes with the tetra starter line so I doubt it's very strong? I've added a pothos in the hope of getting nitrates down as my tap water is quite high in nitrates. However I'm pretty sure a lot of the 'algae' I'm getting is cyanobacteria which I'm just reading tonight happens when there isn't enough nitrates? So now I'm confused. Also low flow but I thought my tank had pretty good flow, is there a way to move more water around gently, without a powerhead etc? Already have an internal power filter and two air stones (running on one USB air pump so not that strong) and don't want it to be too strong for my neon tetras etc. In the meantime I'm trying to figure out an algae cleaning crew. Part of my problem is I'm struggling to identify what algae types I have. I have some diatom and green spot but I actually don't mind those and everything seems to eat it anyway. I have only a small amount of BBA which I can remove manually so far. There is a lot of what I think is some sort of hair algae though? It's not really hairy or stringy (though I do have a small amount of string algae too) it's more like a soft almost smooth spongy texture that keeps growing on leaves and driftwood mostly. There is also a lot of (I think) blue green algae and a bit what looks like the blue green algae but red coloured. However the soft algae and the blue green coloured stuff is kind of growing amongst or on top of each other so I'm not really sure what I'm looking at really it might not even be two different algaes maybe it just looks different colour depending on what's behind it? My main issue is keeping the leaves of plants clean, not too worried about the glass and hard scape. I've heard otocinclus are good for that however I've also read they don't eat hair algae? I don't like amano shrimp as I've heard some horror stories that put me off plus I think they are kind of creepy. Cherry shrimp would be ok if they would help but don't know if they would eat the hair algae or cyano? Also don't want them to overpopulate. I don't want any snails that will overpopulate either so I'm considering nerites but don't want those ugly eggs everywhere so I'm unsure. Do they even eat hair algae? I don't mind the diatoms and green spot they are easy to clean and a little on the hardscape looks kind of nice. Any ideas? Oh and an aside question while I'm here, if Alternanthera reineckii mini melts completely - leaves and stems - do I assume it's dead or can it regrow from the roots? It did well for a month or two grew loads of leaves but then started melting. Thanks for anyone who reads all of that! Hope it makes sense, halfway through my second night shift here and my brain is a little fried. Link to comment Share on other sites More sharing options...
