32W for 1.5ft tank?

[wenwei]

it depend on your surounding temperature. Fan can only reduce temperature by 2 or 3 degree.

okay. think it wont help much even if i add another fan. Have to live with it.

[wenwei]

It mainly depend on your plant. What plant are you having? 36W should be enough for most of the plants

i am still in the planning stage. Tentatively, i guess i will be growing some green leaves and red leaves stem plant in the background. As for the foreground, wan to look for some plants the creeps along the ground.

Any suggestions for the forground plants? Saw some guy plant some plants thats creeps but dunnoe whats its name. Its not glosso and its leaves are bigger than HC. sorry that i cant find the photo to show.

[wenwei]

i understand that red leaves plants generally need more light so i am kind of worried if 36W is not enough as i also wan my forground plants to creep.

Hi wenwei, sorry for the late reply, was playing Gears of War 2 over the weekend! (off topic!!)

Anyway, I am injecting 2 bubbles per second.

My tank information so that you may compare better:
- 25L
- 2FT X 0.65FT X 0.68 - (Length X Width X Height)
- Nano Tank Setup: Riccia, Fisseden, HC and some creepers.
- X2 T5 24W/10K.

I cannot correct you on flow, as this is a personal preference and is something that all of us can debate on forever.

I personally believe that the flow-rate in the tank has too be good. It spreads the nutrients, kicks up all the "dust" as I call it so that the filter can suck it up. For me I put the rain-bar UNDER the surface of the water and face it up for the surface water agitation

I do not dose it with fertilisers (not regularly that is). Like twice a month and probably does not help that much as I change 10%~20% of the water 2 days. I leave the few fish to be the nutrients.

One more thing, it took me 6 months to get it right with the plant tank at work. The one at home is going thru numerous trial and errors.

I never think that there is one sure fire way. There are just too many variables.

My last Algae-stand with my tank was to change 10% of the water everyday for 5 days. The next week I did it 3 times, and the following 2 times.

Hope all this information and random thoughts help you.

very interesting... may i ask how much Co2 are u injecting into your tank?... by doing so, will ur Co2 level rise during the night? you surface agitation is created by a fan?

dont think I will be using a reactor also.. i have this idea that good flow rate will bring about better growth. Not sure how true is it, please correct me if I am wrong.

HAHA.. no problems. thanks for all your feedback.

Anyway, went to NA today. the only choice and stock available is a 24W bulbs. So i decided to go with 2 X 24W. Will see how things go from there. Hopefully its enough. Crossing my fingers~~

I guess I will follow the drop checker colour when dosing CO2, hope it works.

Interesting way of creating fow in the tank. Read about it, and many say good flowrate will improve plants growth. Will be increasing my flowrate. Thanks.

Hmm, something i always wanted to know. What is the purpose of frequent changing of tank water? How do we know if the amount of water we change is enough.

water change help to reset water parameter, inchase you are over dose you fert dossing. typically change 30% to 50% weekly. If you follow estimate index (EI) dossing, then it is necessary to do weekly water change.

Ooo..I see. am I right to say that normally the plants wun be able to take in most of the liquid fertiliser, so a water change is needed. if water change is not done, excess nutrients in water will cause algae bloom?

[Shadow]

It depend how much you dose the fertelizer. If you follow EI dossing regime, then you will end up with excess nutrient at the end of the week. The idea of EI is to dose as much as nutrient without cuasing problem to the fauna. Once you make sure that the plants have enough nutrient, the only possible problem would be because of CO2 level. Excess nutrient will not cause algae bloom (according to Tom Barr, he did research on this) unless you dose Amonia. However excess nutrient will kill your fauna

Okay.. thanks. Will do water change weekly. going to start my tank next week... cant wait.. haha

hehe... have fun with your tank

- 2~3 bubbles are second.
- Rainbar below the surface of the water facing up
- Plant tank in the office is mostly cold cause I sit under the aircon
- I don't worry about the weekends as my lighting drops to 3 hours a day
- Flow rate is a personal preference, the rule of thumb is, "What I do today, I will see in 7 days" So you just have to see what works for you
- As I now say, everything is a guideline and there are exceptions to the rules.

Thanks alot for sharing.. will take note of what you said during my setup...
