After about 40 weeks, I had to remove one type of plant from this tank but everything else is growing well in this nano Iwagumi tank.
Nice Background Gone
With much pain, I had to remove the Eleocharis plants that had served as a nice background for this tank. There are two reasons for this decision that I made.
Firstly, it had been covered with algae that don’t seem to go away.
Secondly, these plants won’t grow back tall once you’ve have trimmed it all the way down to the substrate level. The only ones that do, are the newer ones that come from new runners.
I pulled all of it out of the tank and subsequently the rest that remains.
Return Of The Gratiola Plants
They never left but it’s nice to finally see what the Gratiola plants look like when they’re able to grow undisturbed. Previously, the carpeting plants (and algae) had overtaken them.
The Gratiola viscidula are stem plants that don’t grow very tall and I think you could use nicely as a foreground and middleground plant. They don’t grow very big too and should be right at home in a nano tank.
I learned to set aside my fear about trimming plants all the way to the substrate level because of this Gratiola plant. Plants can grow back and nicer than ever after a hard trim. It really can.
Moved The Shrimps
I know I shouldn’t resort to chemical treatments to get rid of algae unless as a last resort. Plants might be able to withstand the chemical treatment but your livestock might not.
That’s why I had the shrimps moved to another tank before treatment began.
I overdosed the tank a little with Seachem Flourish Excel for a couple of days to a week and it did reduce the number of algae visible in this tank. There are some still visible on the stones but it gave the stones a nice aged look.
I may or may not want to completely remove those algae on the stones.
Algae Under Control For Now
Having said that, using chemicals to kill algae is just a quick fix. You’d really need to find the cause of it and in my case, it was too much light. As in, the intensity was too high.
Even since I modified my LED lights with inline dimmers, and reduced the intensity by half, the algae problem is under control. So, reducing the light intensity to kill algae works. You should try it.
Some algae are just very hard to kill with lesser light alone.
Frequent Trimming Required
It isn’t much maintenance but a tank that is almost fully covered with carpeting plants like this one need frequent trimming. Care to share your tips about carpeting plants?
