    I seens this dark spot for sometime now... but thought that it is normal. But seems to be getting out of hand, they are found on the Java fern, Alternanthera reineckii 'roseafolia' and the unkown plant.

    This is Crappy! First I got BGA, now I got BBA... Hope I can get my BSc soon!

    How come I always get the good stuff!

    PeterGwee must be your fault lah! [] Time to add Nitro!

    Does it look at yours?

    Taken from Aquabotanic Forum.
    Classic BBA ...You have low CO2 level like what I told you last time!!!..Get it up to 20-30ppm during the lighting period. Next, prune heavily on those affected areas and do a 50% water change after that...blackout is pretty useless for this bugger.

    Seems like it... Xcept for the clarity of the pics... My tank need some Nitro to BURN! Any brand of NOS to recommend??

    According to the url ref... Need to removed affected leaves after controlling phosphates... Like that no leave left liao totally Botak!!

    Erhmmm...I wrote you have Low CO2 level...not high PO4! Get your CO2 level right..from what I can see from your last posting on your tank parameters, your KH is 1? Did you add baking soda? Get it to 3-5 but do it slowly..add max of 2dKH per 24hrs..Then inject CO2 to bring down the pH to obtain 20-30ppm of CO2 during lighting period.

    PeterGwee:
    Yesterday tested my KH to be 3. Ph seems to be more basic instead of acidic ~7.5. Added 1/2 teaspoon of "Bicarbonate of soda" aka "Baking Soda" to the tank.

    This morning, Tested PH solution become dark green out of the colour code table. water PH is suspected to be about 8. Tested the KH to 7... [] 1/2 teaspoon FLAT mean so much!

    Now pumping CO2 at 3-4bbs (planning 24hrs) hopeful to bring down the PH by Monday. IF KH 7 and PH 7.3 then will be in the correct region! "refering to above table".

    ??? Is it advisable to use PH modifier to reduce PH? Also a PH pen would defintely more convenient!

    Never ever use other stuff to lower your pH other than CO2! Get yourself a test pen lah...Much easier. Your KH is fine for now...just lower your pH to 20-30ppm range with respect to your KH value for the entire lighting period.

    Use the following to set your CO2

    Peter, I am not good with Chemistry...never study before.

    Currently I have a PH Test kit, KH and FE test kits. As you can see I do not have a CO2 test kit yet. From your expertise, whats my best bet? Just monitor the PH will do Or...get a CO2 test kit?

    KnightStriker...get a KH and pH test kit will do..no need the so called CO2 test kit. If money is no problem, I would prefer you get a pH test pen but make sure you calibrate it properly first. Get the CO2 level from pH/KH readings.

    Yee arr...wa lao...chim table. added to my bookmarks. thanks!

    Neat Calculator!...Moderators...cut and paste the javascripts...heh heh..

    I am using a PH Indicator Solution that comes with a Charting table measurment 6 to 7.6, its from Aquarium Pharmeceuticals Inc. In fact I was abt to check out local pharmecies to see if there is paper type one...just in case when the solution runs out.

    Currently close monitoring on water conditions to avoid a change of ±0.4 diff.

    wow...after re-calibrating the FE and the CO2 level, I get to see lovely little bubbles within 1 hour. BTW, the CO2 was adjusted according to Peter's recommendation to PH/KH table.

    Peter, you are right, I dun need a CO2 test kit after all. Ha Ha!

    Limsteel, from the picture, your plant seemed to be stunted. You may want to look at your fertilisation. If possible, you can share your fertilisation regime with us.

    Reducing the KH will reduce the pH. To reduce KH, just make a water change. The KH of our tap water is pretty low.

    Stunt... yah the growth stop for a while already... felt something wrong... last 2 week went on a weekend trip and never change water and add fert.

    last week again was BBQing at a Chalet So no change water & add Fert again. Think that why the BBA came in.

    Sunday night just added FE, KSO4, MgSO4 and PNK...

    Make sure you correct your CO2 level which is critical to proper uptake of nutrients...if not you would have more problems!

    No water change. That's bad. If you are adding macros N, P, K, etc., water change is essential.

    This is because macros are added in relatively large quantities. Water change will regulate the level of these nutrients. If you do not make water change, you may get big accumulation of the nutrients.

    BTW, the plant in the picture looks like it is lacking in Ca.

    I started off planted tank, reading Articles from the net. along the way learnt more and more.

    Now going toward water chemistry... Tao Tia lah (headaches)!Aquascaping, Dead fish, poor lighting, Algae, plant stunt... what else can come?

    Yo BC, anywhere to get CA-NO3, was looking for KNO3 whole day cannot find.
