I can't advice on TDS and I studied accounts, no chemistry. But obvious the lighting not enough.
After changing 10% of distilled water the tds reading went down to 300ppm
The Algae that grows on surfaces is a different strain from Green Water Algae, which is suspended in the water, making it green. When this Green Water Algae dies, it lands on the top surfaces and turns brown.

Oasis, that TDS level is fine. Adding Old Sea Mud should increase TDS. I believe it's basically montmorillonite or something close. Brown algae growing on your rocks is normal. You should start worrying it if was BBA or something else. 68 is quite low and I think you should cut back on the distilled water now. You might want to read up in the Planted tanks section, so you understand better on what is going on in your tank.

@Ted,
Green water is a suspension of both animal and plant matter, in the form of protists and free-floating algae. In most green water cultures you will encounter Euglena, a type of zooplankton that can photosynthesize by itself. If you want to encourage green water, purchase a starter culture from the GC shopkeeper, keep a vat or tank close to source of sunlight and keep one or two goldfish, or guppies/platies in there along with snails. Over time, the green water will bloom to insane levels, then you can feed it to your fry with a dropper or turkey baster.

Hi stormhawk, my tap water tds is measure at about 77ppm currently. Last measure of my tank water last night is ph7.5 and tds 280ppm. Do i still need to cut back on distilled water? can i check what is BBA?
This is stressful man trying to get water parameters right. On the verge of giving up
Is it advisable le for me to start all over again?
Ah, thanks for the tip. Actually I prefer my green tank to be my main fish tank, as I am doing now, but I don't know what strain it is, just that it's green. It may be odd, but somehow, I relish green water very much, and I am convinced my fish also feel comfortable in it than in clear water, lol.
By green water, of course I mean nice and balanced clean green water and not murky and unhealthy cloudy water.
But I will go to GC to get the algae when I want to cultivate a pure culture later.

I think you can start to cut back on your distilled water. What is the current pH of your tap water? Mine is 7.2 and 120+ TDS out of the tap. You can probably do 50/50 mix of tap water and distilled water for the next few water changes. The pH should be dropping by now, but if it stays the same then it's probably your rocks that is keeping it alkaline.
For a pic of BBA, the cause and remedy, see this blog:

Scroll down and you will see BBA pictures. It's one of the hardest to eradicate.

Hi stormhawk, the water straight from my tap ph is 7.5 and tds 90. I'm using biohome plus in my ehiem canister filter. Heard that there is a batch that fluctuate ph is that true?
On a side note my plants have some web like substance. Looks like cob webs any idea what is that?
i have remove all the rocks yesterday afternoon and water change 10%. Which mean the tank has only soil and plants in it.
this am when i measure my ph is about 7.5 . sigh
Looks like your soil is not able to buffer the ph down. Think you might want to consider changing the substance.
