I think there's good circulation? when occasionally stuff gets stirred up from the gravel the filter clears it in less than 20 min.
It's a 20 gallon long. Marineland Penguin 170 biowheel.
I have 12 fish (7 cherry barb, 1 plakat betta, 2 kuhli loaches, 2 platyfish) 1 nerite snail, a bunch of malaysian trumpet snails.
Low tech, low light- "daylight spectrum" T12 20 watt bulb on 6 hrs per day
I try to feed a variety, and several months ditched the low quality flake food for new stuff that doesn't have fillers- I have mostly omega-one brands. I give them two kinds of flake, spirulina wafer, shrimp pellet, betta micropellets, betta flake, freeze-dried bloodworms, zucchini, peas, occasionally fruit flies I catch in the house. Feed once a day, once a week fast, day after that give the pea. On days they get flake (every other day, or every third day) I feed twice a day, but very small pinch. They go crazy for it. Gone in less than a minute.There's usually not much left over for the kuhlis to find, sometimes I try to put a bit of shrimp pellet or spirulina wafer straight into their cave where the other fish don't go so easy. Maybe that sounds complicated, but I just alternate what they get- this week they haven't got zucchini yet, so that's why I worried the lighter poo was parasite not food-related.
I wasn't giving any ferts for a long time but some of my plants were turning yellow, or melting away so I put in 1 root tab broken up (per the whole tank- did not want at all to overdo it) and 4-5 drops of seachem flourish, once a week (the root tab I did once 2 weeks ago have not added more yet). I'm seeing better plant color and root growth since, but think maybe they don't need the flourish and more iron from the root tabs instead? Not sure. I was thinking of next week foregoing the flourish and putting in another root tab... any advice on that is helpful, thanks. I'm still new to plants!
Oh, I thought it was too much nutrients because although the plants are growing better now, there's still have black and dark green splotches on many older leaves- it doesn't rub off- I assumed this was the plant having some deficiency, not algae.
It's the platyfish that had stringy pale poo. Today one had normal poo, the other one stringy white, almost clear. They both came from online fish dealer. The one that died recently was platyfish too.
