Low Lightning With Your Osaka Series!

[s007]

Here is what i have asked their suport service:

Subject : Low lightning with your osaka series!

Request : Hello ive recently purchased yout Fluval Osaka 260 with cabinet and light filter and so on.. (all in one kit). As i have presurized co2 and planted tank the thing is as the light you provided with it is 2x 24W T5HO but obviously for this size of the tank its not even 1WPG its aproximatly 0.7 WPG where planted tanks with co2 require at least 2WPG, strange as by looking at your picture of Osaka series they are all heavily planted tanks - how come? I dont plan t limit myself with just low light plants so as you can see i have a problem here. Any suggestion or help?
Thank you.
Sergey

Dear Mr Fedak.
Thank you for your e-mail.
Firstly, the Osaka 260 is supplied with 2x39w lights
The volume of water in the Osaka 260,after displacement is around 45 Gallons,so the lighting system is correct at over 1 WPG ( watt per gallon ) .
For the aquarium to hold its capacity of 260 Litres,you would have to fill it to overflowing and with no substrate of decor.

Hope this helps.

Kind Regards.

So does it mean as i dose co2 with 30/31 bubles per minute i shuld be fine?
Cheers

for this size of the tank its not even 1WPG its aproximatly 0.7 WPG, where planted tanks with co2 require at least 2WPG

do they? I think you are getting confused, what we say is generally tanks with 2WPG+ require CO2 injection due to the faster growth and higher nutrient demand. CO2 injection can be used at any level of lighting.

Besides, 0.7wpg is enough to grow quite a few species of tanks. Here is Andy's tank @ 0.9WPG: http/www.fishforums.net/index.php?showtopic=244998

As said by Aaron above.

You have 2WPG on the WPG scale because you have T5HO lighting which mashes the T12 WPG rule into the ground!!! 39W of T5HO will pentrate further than 80W of T12 as well!!!

Therefore you have now gone public on 'criticising' a large manufacturer when the facts are virtually the opposite.

A planted tank with pressurised CO2 does not 'need' a level of light. It can have 0.1WPG. I used pressurised CO2 on 0.6WPG, 2.5WPG, 0.9WPG and my current 1.1WPG.

However a tank over 2WPG (or 1-1.5WPG T5HO) will most definately need pressurised. CO2 addition does not mean you need more light but more light may mean you need pressurised CO2.

You really should have got the lighting W right too


The next thing you should have seen is that although the advert suggests a planted tank it has only got 'low light' plants in it. that is the Swords along the back and the creeping jenny along the left. All the others are not aquatic plants I guess you didn't feel like pointing this out to them

Anyway the setup in itself is pretty good. It has enough light for you to grow any plant you want as it is in the 2WPG region when allowing for the better lighting. An added bonus is that you can alter the height of the lights. Therefore you can raise them to have a lower light tank or lower them to have a higher light tank.

Oh and there is no such thing as a 'low light' plant. Try to think more of low and high CO2 than light. People have gone on about low and high light plants for far too long and always ignore the fact that with low and high light they also increase CO2 and nutrient. No idea why. It seems people have ignored this for a long long time and only now are a few starting to think 'Hang on a minute. Is it really true?'

Once you reach 'good light' then pushing the CO2 up will make your tank succesful at virtually any species. If it doesn't then the user has something else wrong.

Next time you want to publically moan at a manufacturer then you have to consider that they are not aiming at aquascapers!! They are aiming at the average person and using plants as a nice way to make their tank look nice. These tanks are designed to look great and of course Fluval want to sell as many as possible.

Most aquascapers do not expect to buy a one piece package. they buy a tank and then buy lighting and then buy other equipment etc. You really do need to get into the real world on this one.

BTW nice aquarium

So does it mean as i dose co2 with 30/31 bubles per minute i shuld be fine?

How would the chap at Fluval know the answer to this? Your 30/31bpm may be 200bpm for me. different bubble counters and different diffusion efficiencies mean different bpm for each user to get to the same level.

I would suggest 30/31bpm is incredibly low and well under 30ppm. This puts you into the 'low CO2' bracket and therefore what is the complaint about in the first place?

Thanks for reply AC, first of all i DID NOT MOAN all i done is ASKED them about lightning that they provide as accoung to THIS FORUM people replied to me that my light is way too low 0.7 and according to the place where i bought light it stated 2x 24W not 39W each!

Secondly when i asked "So does it mean as i dose co2 with 30/31 bubles per minute i shuld be fine?" i asked people here i did not include this in email to them please read before saying what kind of question i ask "im new to co2" and better to be safe then sorry i dont want to underdose or overdose as my drop checker did not arrice yer and ive just placed pressure for 30 bpm AS I STILL DONT UNDERSTAND COUNTINGS OF ppm.

No offence mate just curious.

For the latter part then I am sorry. It looked like you were asking the question in the e-mail

As for bpm. It would be a good place to start at 1bps (60bpm) For the lighting that you have with the aquarium and the size of the aquarium allied with good diffusion/circulation then I would expect you to end up in the region of 3-4bps!!! (180-240bpm) Poorer diffusion and/or circulation will mean more. More plants means more CO2.

However I would not push it up that high until you get your drop checker arrives. When it arrives move it around the tank every couple of days and see what the levels are like all the way around. Also watch your fish for signs of it being too high.

As a guide my 125Ltr tank with 0.9WPG T5HO was at 3nps with low flow and when I got it sorted out went down to 2bps.

I currently have 1.1WPG of LED but raised pretty high up from the tank due to the increased PAR compared to fluorescent (Assume 1WPG = 3WPG!!!!) and am still running at 1bps because I have less plants in this scape

Actually, if you were to read my replies to your posts (which you evidently skipped over), you would have found that you were advised otherwise...

I also also advised you that counting BPM and calculating ppm via KH and pH are not accurate methods of estimating CO2 levels...
