Algea Problems
First of all ill start with the tank specs.
27G Long 100W of NO lighting PH between 7.2-6.9 DIY CO2 injected into my filter GH 14 KH 7 PMDD dosed daily NO3 dosed every 3 days because it is depleted quickly in about 2 days about 5ppm dosed PO4 dosed when I remember which usually ends up being once a week dose about 1 little bead of triple super phosphate mixed with water...not quite sure how much it adds...probally should but I cant imagine it very much KCL dosed when I remember which usually is about twice a week at about 2-3ppm Very heavy planted it my opinion but see alt.binaries.aquaria for the pic if you want to see. Mostly with water wisteria and jungle val. I started out stupid and didnt have the money to fill it with plants so i planted the cuttings when they grew..and from this i developed an algae problem..BBA and such. The plant has been planted heavy for at least 2 months but I cant seem to keep the algae at bay..I trim all the algae off the leaves at least twice a week. I want to get some slower growing plants but im afriad they will be coated in algae in no time if i trim back and plant them.. Should i be leting the NO3 drop to zero or should i keep it at a stable 5ppm or so...should i dose more PO4? or is that my problem?..i dont think it is excess PO4 that is my problem..maybe not enough? Or maybe im just impatient and i should give it more time? Any suggestions would be great. Thanks Ryan Wilson |

Algea Problems
27G Long
100W of NO lighting PH between 7.2-6.9 DIY CO2 injected into my filter I'm sure quite a few people will disagree with me, but 100W on a 27G long is a good amount of light; I would be using a compressed system. DIY is great for lower light tanks but I was personally very unsuccessful maintaing CO2 levels near 25-30ppm with DIY and high light. Should i be leting the NO3 drop to zero or should i keep it at a stable 5ppm or so...should i dose more PO4? or is that my problem?..i dont think it is excess PO4 that is my problem..maybe not enough? Or maybe im just impatient and i should give it more time? Here's my technique for dosing, which is mostly inspired from Tom Barr's method with a few changes that make sense to me... I think it's important to develop a "hybrid" technique that suites you the best, this isn't the only way to do it. I add NO3 and PO4 three times a week, traces three times a week, K at water change... remember you need ~20ppm K+ I would prolly bump up your dosing... anyhow it goes something like this: day 1. Water change, traces, K, PO4 day 2. NO3 dosed day 3. day 4. traces, NO3, PO4 day 5. day 6. traces, NO3, PO4 day 7. I start with enough NO3 and PO4 per dose to bring the tank to 5ppm and 0.2ppm... I test before the water change, I like to see zero levels of NO3 and PO4 before the change... if they are zero I start upping the N and P dosing but don't exceed 10ppm N and 1ppm PO4... so assuming a zero-order nutrient uptake, you get a saw-t0oth pattern 3 times a week. You could keep N levels a bit higher I'm keeping them low trying to trigger good color in r. wallichii. Cheers, Jeff Ludwig |
