3 ft Moss Tank set up...

[VTan]

Hi all,

I am considering to change my current tank set to less maintenance tank.
Current:
3 ft tank with 90 watts FL(about 350l)

Tonina SP
Taiwan moss
Tiger lotus

About 90fishes inside,
30 cardinal, emperor
15 pencils, golden and single line pencil
10 sparkling gourami
10 cory, pleco, whiptail
5 apistos
20 platy, rainbow

converting to a
All moss tank(Taiwan, christmas, etc...)

Please advise if the bioload is too heavy for an all moss setup,
causing high algae growth, as now I am seeing spot algae with weekly 10% WC.

My objective is to reduce the water change to monthly, and reducing lightning
if possible... Please advise...

+ CO2 and lightning from 5~9am and 6~11pm
CO2 about 2 BPS...

Filter: 2026 and a internal juwel filter.

Please advise...

Hi Vtan,
Your bioload is too high for a 3 feet tank. Way too high, doesn't matter moss or any other tank..best to reduce.

if bioload too high what will happen??? i got a 3 footer at workplace with 300 tetras. that time cheap so buy alot. now all grown up the whole tank look like tetra.

Thanks, where can I find the calculation for freshwater fish to water ratio?
Please advise... thanks...

can consider replacing shrimps for your fishes.

Not sure about you. But I would drop the light to perhaps 2 x 30 FL lighting for 10 hours. 1 x 30 if tank is near the window where sunlight gets to it. Water change may not be required but you might need to add PO4 to your tank unless you are sure that you overfeed your fishes. Water change can be do away with if you lower your fish load to less than 50% of your current load while having a good filter.

Reduce your fish bioload like many others have said. I'd reduce it to half minimum personally. 30 cardinals by themselves will be good.

If you want to reduce water change frequency or completely, consider changing to non-CO2. Non-CO2 will allow you to do no water changes, only top ups of water evaporated. Bioload becomes a important factor though, too much ammonia = trouble.

The moss has to be in very large amount though, otherwise algae will just visit.

Moss grows best when the bioload is low. Considering your high bioload and infrequent water change, your moss may still grow albeit not as nicely. If you look at the tanks in Bioplast, you will notice the bioload is low and all the mosses are growing very well. Of course, the temp of the tank plays a part as well.

Mine is also a 3 footer with slightly less than 50 fishes and I am finding the tank too crowded. Do give it some thought.

Cheers!

Thanks for the all your kind input.

I guess I will reduce my bioload gradually then reduce my plants.

May add a chiller... for the moss.

Can any one advise if Resun CL300 sufficient for a 3 ft tank??? Thanks...

Hi,

personally i'm not too sure abt plants management but
for ur bioload is too high..

here's 3 options for u to choose

-Reduce bioload then can Do less water change
-Remain same bioload and Do more water change..
-Remain same bioload and upgrade tank to 4x2x2 and can Do less water change

from my experience..
high bioload + overcrowding + small tank = disaster waiting to happen

Cheers

Thanks, reducing gradually by giving away species by species...
