Mike K. Posted February 17, 2022 Share Posted February 17, 2022 (edited) Hey people, greetings. ✌️👍 Anyone Maybe can help? What cause and what kind of algae is that? Tip; when shakin plant by hand it Fall off. Plants seems healthy. It's combined with green dust algae on the Glass which I have problem too. Parameters: 112l, fluval 207 with sponges and Matrix, pressured Co2, RO mineralized to GH 7,.Kh 1-2, Ca 35, Mg 9, K 15. No3 10, PO4 (active substrate) so not present in water column. 0.3ppm Daily. Fe 0.1 or less (micro profito Daily 1.5ml) CO2 30 (spreading by circulator) , 8h light, chihiros A II 801 30W 8000k (dimmed to 20% for fight algae) DIY power led 39W (dimmed 50% for fight algae) (white full spectrum , pink full spectrum, Deep red, Royal blue, 4000k, 6000k,8000k) Not overcrowded tank, 15, cardinal tetras, 6x otocinclus, 7x amano shrimp, 6x Behleri. (barbs at Photo are in other tank) I have other fertilizers like tropica specialized, tropica premium, seachem trace, Fe, some salts to can add separately... Edited February 17, 2022 by Mike K.

DEFREESE AQUARIUMS Posted February 17, 2022 Share Posted February 17, 2022 (edited) On the one java pictures it appears to be hair/fuzz algae or BBA. Hard to tell at the angle, below are some videos that should help you out.

Beardedbillygoat1975 Posted February 17, 2022 Share Posted February 17, 2022 @Mike K.I think it is black beard algae. How is the circulation around the tank? I think you need more fast growing stems to soak up what you are putting in and out-compete the algae. 2 Link to comment Share on other sites More sharing options...

Mmiller2001 Posted February 18, 2022 Share Posted February 18, 2022 How old is the tank? How much turnover do you have? How much are you dosing all together (in ppm per week). Link to comment Share on other sites More sharing options...

How much are you dosing all together (in ppm per week). 2 years Old, 900l/h declared around 500l/h real turnover. Now I changed some fert rates up and back to light 100% and 30% chihiros and situation gets better but not yet fixed. Currert fertilizing Daily: 3ml profito, 3ppm No3, 2ppm K, 0.5ppm Po4. Weekly (0.25 Fe from Profito, 21ppm No3, 14ppm K, 3.5ppm Po4.) When situation was worst there was 1.5ml profito, 1.5ppm No3, 1ppm K, 0.2ppm Po4.

Now I changed some fert rates up and back to light 100% and 30% chihiros and situation gets better but not yet fixed. How long ago did you make this change? What percent water changes are you doing and how often? With the information I have now it seems like the circulation in the tank is a bit low. You mention if you shake the plants it falls off. Try to increase flow around the plants so the filters can pick up the debris. Now everything I say, below, is based off a 50% water change (assumed). If you are doing a 50% change then your accumulation totals are 42ppm NO3, 28ppm K, 7ppm PO4. The GDA could be from the heavy NO3. Now, if you are doing less than 50% water changes, then these numbers are higher. When I'm a bit too high on NO3, I will begin seeing GDA. I would dose around 10 to 12ppm per week, so my accumulation total is 20-24ppm NO3. I'm not familiar with Profito, is it a Micro mix? Are you dosing Micros such as Boron, Copper and so on? .25ppm Fe might be too low for a weekly dose, I'd be tempted to move that to .4ppm Fe a week. The other numbers look good (from EI perspective).

I try 1.5ppm No3 instead of 3ppm Daily to lower the dosage. You May be right. Im doing like 40% w. Change. Profito (micro ingridients) ; it's somthing like trace (tropica premium, seachem trace) but in addition got some extra things as you can check down: Fe(2+): 0,12% K: 0,7% Mg: 0,09% Mn: 0,04% I: 0,02% B: 0,008% Cu, Mo, Zn, Li: 0,002% Ni, Co, Al, Sn, F: 0,001% V, Se: 0,0005% Link to comment Share on other sites More sharing options...

Numbers wise, everything else looks in range after lowering NO3. See if you can boost flow a bit to grab up the settling particulates. I'd also do some mild gravel vacuuming just to tidy up a bit.

Yep I can add more Fe, got some "Fe hybrid" stand alone Fe fert. I bought today inline co2 diffuser (ProGrow even Flow) so now external filter spreading ultra Tiny bubbles around the tank it should help also with Co2 distribution. Tomorrow Glass cleaning and some vaccuming, plants shakin'. We'll See. I put Photo of the New diffuser. 1 Link to comment Share on other sites More sharing options...
