Dear Tom ,

I have been into the hobby of aquarium for several years and have just started a planted set up. I am very impresed vwith your site . It has helped me a lot.

My Aquarium detalis :
size:- 48"x21"x24"LBH,

substrate :-a mixture of ada, boiled peatmoss ,laterite ,2mm grade quartz sand and 4 tbsp of dolomite powder all mixed for the base .

Lighting :- 36 wts PL 865k 15 nos for 11 hours

plants :-Ludwigia arucata ,hygrophilla polysperma,difformisa , temple ,ambulia ,
Gayi, Rotala Macaranda, Roundifolia, Aromatica, Nuphor Japonica, Java Fern, Java moss, Needle Grass, Himenthius, Sword Amazon, etc.

co2:- 3bps

fertilization :- following your estimative index . i dose

alternatively :- 20 ml KNO3 and 10 ml KHPO4 on day 1 ,3 and 5
micro nutrients on days 2,4,6
day7 20% water change

problems :- for past 3 weeks the results have been fantastic the new growth in my plants have been larger than the plants acquired

Recently I noted the leaves on my indicator plants ie: Temple and polysperma turing crispy like wafers and the new leaves of Polysperma cupping up. I added a small amount of Argonte sand for extra calcium. Still the problem persists. Kindly help.

Hi,

You may want to try any or all of the following:

1. Slowly and carefully increase your c02. C02 and nutrients need to be INCREASED as plant bio-mass increases. Have you done this as the plants have grown in?

2. Up your weekly water change to 50%. Is there a reason for you limiting to 20%?

3. Decrease light duration from 15 to 10 hours. No need for that much. 8-12 is plenty for most plants.

I think your issues are more c02 related....... How are you introducing c02 and measuring it?

Have you tried the Barr GH booster at all? Used at each water change..rather than adding calcium specifically........

Do you use Excel at all?

Don't forget your filter maintenance as this can have a detrimental effect as well.

Hope this helps.

That seems to be a 100 gallon tank, so I doubt that 3 bbs is enough CO2 for it. But, do you have only a single 36 watt light? If so, you have a low light (very low light) tank, and any CO2 at all will be good for the plants.
