hi!
This is my juwel rio 300 tank. I don't know if anyone here is familiar with juwel, but it's some starter aquarium kit from Germany. It has a cover, internal filter and weak lighting. It is 120x55x60cm. 92gal.
I had the more or less same setup for like 4 years. 20 days ago, finally I decided to get new soil. The old one was full of mulm and osmocote diy ferts, snail shells etc. It was on sale so I decided to go for it.
Daily dosing, macro diy solution NPK 5-4-27 per week, magnesium 2ppm/week (I saw somewhere to add Mg in mix, but I don't know why I'm doing it since I add it with remineralization). RO 100%, remineralisation with mgso4 and calcium sulphate WC every week 50%.
Micro easylife profito 45ml/week, additionally iron in form of easylife ferro 20ml/week (0,57 ppm/week).
For filtration I have 3 filters, eheim 4+ 600, oase 850 and had sitting around old tetra ex 800 so I added that one also. Filled with fine sponge and cotton.
For additional flow I have stream pump sicce voyager nano. I opt for 1,3ph drop before lights. KH should be 0, and GH around 5-6. Ca:MG is around 3:1.
Lighting aquagrow uniq fs 900 (cca 138w) + jbl solar natur 57w 105cm. 8h per day.
This photo is from yesterday. Plants are growing but are covered with brown algae. I heard it comes from tap and is related to silicates but since I only use RO water I'm not sure about that. On second photo you can see that stuff next to snail doing their stuff. It looks like some small tubes. Ant they are all around the tank. I couldn't identify them but i suppose this is some sort of brown algae. I suppose it will go away with time.
With new soil I didn't change my dosing rutine, nor did I dim my lights. Maybe I should have? I do waterchanges every 4 days 50% for three weeks now.
In tank there are still no fish. I plan to return them today. And maybe to reduce their number. I have like 30 neons, 25 rummy nose tetras, 2 or 3 emperor tetras, 7 cory sterbai, 15 congo tetras, one pleco L129, 2 SAE and like dozen ottos. And one dark blue shrimp I never know when or how got in my tank. I plan to reduce that to lower the poop and feeding. Cause in such tank is difficult to not overfeed some and starve other fish, so probably I put to much food into tank to feed that one cory or tetra in the corner. What's your take on this matter? Should I ditch some of the species or let it be as is. I plan to give away the L129 pleco for sure.
Any suggestions? Do you notice any problems and how to fix them. Stunted amania nasea gold I try to bring back, which was good until I moved her a bit. Or was in shadow for some time. I had cryptocoryne pink flamingo, and it grew great until it got shaded and from then it went bad and died. AR mini was most of the time stunted. Especially if I replanted it. Limnophila aromatica, which i love, just crawls and bends on the bottom and wont grow up (to much light?!).
Sorry for the grammar in advance. xD
Here are some pic of the tank before the soil change.
