Bro, You have to accept that there is no perfect world out there... if you are not willing to wait or cannot tahan for the life cycle of the GDA... then use the algae cleaner to scrap off the dust or you take out your fish and watch in other tank....

saw two small nurse sharks selling at SengSong supermart.... :fear: last Sunday...

Yes.... I even found (in Taiwan) one LED system that interface with software that can tell you the total output (power) you used for the day for each track (assuming one track is about 6 LED) ... of coz the intensity and colour temperture of each track is configurable for different simulations...

Frankly spreaking... the major difference is the UNKOWN and UNTESTED product quality and your luck!!!

What if I tell you the less expensive one also has these above features now plus wireless control..??.. .. I am doing a product review in my thread soon when I received the new toy...

I was surprised too.. ... given that I used to have 3x250W MH + 8x39W T5 (6 footer) and 2x150W MH + 2 x 52W T5 (4.5 footer) ... I am still keeping all the T5 but replaced all MHs with Main LED... I think the chillers have less heat to cool down...which contribute to additional power saving... Mike, you are welcome to visit me (PM me when you want to swing over)... best would be end of this month ...as I have a New LED toy arriving with latest technology with at least half or 1/3 of the price of some latest branded LED.. .. with the new toy, I hope to totally replace all the T5 with LED lighting to further cut down the $$$.. It's also my hope not just to save the running cost but also a flexible means for me to improve on the colouration of the SPS with the latest technology...

think around S$487 for the AquaZonic LED+T5 light set (4 feet)..

The main concern I think you should consider would be: 1) whether the water in the Arowana tank is good and stable enough for your FOWLR tank particularly the soft water KH in which you might need to adjust when mixing with salf. 2) the spreading of diseases from your Arowana tank (assuming your Arowana is sick) to your marine fishes. :excl: I am not a hardcore reefer myself although I keep SPS/LPS and many fishes (marines and fresh water discus)... For marine tank, I use NSW to save the trouble and keeping my maintenance cost down. Sometime out of the blue I do DI with salt-mixed and if lazyness strike me.. I just use tap water with anti chlorine... .. For FOWLR tank, I think you can opt for the following: 1) reduce your water change to bi-monthly and do 10-15% water change - if you decided to use the Arowana tank water (the impact might be lesser and you save half effort and $$$) 2) do without DI water but use tap water with anti chlorine (left it over-night after salf mixed) - actually the main cost is the replacement DI of resin NOT the water bills!! 3) buy NSW from the nearest LFS and change water every 2 weeks - minimise trips to LFS and time/efforts to change water... Last but not least...make sure you have a good skimmer....

no problem...you are welcome...

Go to Nanyang Aquaurim in Seletar Farm way...They got LED(blue and white) + 2x T5 light set with remote control (can control the blue/white intensity)... I think AM also selling but not sure if the price are good... expected < $500 for 4 feet... > $500 for 5 feet .. I am using one for my 4.5 feet planted tank.. (just for LPS + fish + rocks should be ok..). but if you want to go for SPS in the future.. you got to replace the whole set as the light set is in full lenght x width.. and lighting is not strong enough to go to the "dark side"..

What are you intend to keep? LPS? SPS? Fish only? or just Rocks??? What is affordable to you?? For my case, I am able to save S$200/month of ultility bill after converting from MHs to LED..

...you too... think is the best approach...

Thank you ... no need to feel jealous.. . I am sure everybody can do that... if they have the passion and strong will to achieve that...

me too.... can I order the chicken rice without the chicken??

ha..haa...as a matter of preferrence, I like that.... do your 3 monkeys including the big female one??

:thumbsup: :bow:

it is not possible to have worms if your reactor is in good circulation mode... mm...something is not right...

Bro, Great deisgn... can you tell me how you come out with the number of LED used and the ratio?

I was thinking on the same line...but since you already have the T5 blue and Purple plus...so, you might want to think of "what if " in the future if you decide to change the T5 to white like bro sunny03... If you want the flexibility of changing the T5 lightings...it would be good to include 2 x violet or/and 2 x Turquoise... :idea:

I would think 25% Warm White and 75% Neutral White would be a better choice...the purple plus actually doesn't cover much of the red specturm ...so you might want to keep the red as is...

I would recommend the following testers if you want more accurate readings... 1) Alkalinity Checker 2) Calcium Checker 3) Nitrite Checker 4) Phosphorus Checker

Thank you very very much...

Wash your zoas clean with fresh water and dig in the fresh water for 10 minutes... expected recovery time is around 2-3 weeks.. depending on your luck some of the zoas might not make it... hope this will help... good luck..

Sure...just PM me your contact and your intended visit time...
