  1. How many different weld or solvent that require for joining?

    Sent from my GT-N7105 using Tapatalk

    Hi bro,

    There are many brands and type of acrylic solvents in the market. People usually use Weldon 3/4 and 16 for acrylic project. Weldon 3 is water thin, very fast set, solvent type adhesive for acrylics joint whereas, Weldon #16 is gel type having stronger bond than 3. It is especially useful where fast cure and high strength are desired for applications such as large housings, signs and industrial fabrications. Beside the above, people also use it to seal leaks for the acrylic tank and it works well.

    For me, I use mainly MTC-90 liquid solvent and Acrifix IR0192(gel type)purchased from DAMA for all my acrylic projects. Quality wise is comparable but price is much cheaper than Weldon brand.

  2. I do not agree with the test result.

    I have being using LED aquarium light since solaris time.

    During that time there is very little choice and is expensive.

    The leds are all running near to peak allowable and the

    life is short

    Today with the price of LED dropping and performance greatly

    improve .Choices are many.

    The prices you paid some come is in relation to the component

    quality ,design ,material quality and service quality.

    LED as we know come in many different bin.

    The more tolerance tight bin is going to cost you more.

    And I mean a drastic different in cost

    That is where the price different fall .

    But on the whole most of the led Light set today have rather

    acceptable quality.

    So the drastic drop off from original spectrum in a short time

    is not possible.Although there are drop off.

    Today the weakest link in any LED light is the power supply.

    Most of the time they are the culpit and upon changing a new unit

    every thing is back to normal.

    Hope this explain why I do not believe in the test result publish

    +1. you got my vote... :cheers:!

  3. If u want cheapest one & dun mind the brand and quality, fish street has a nano doser,

    Taobao one is better than fish-street nano dosing pump with built in digital display and control. I bought it last month round S$71.00 included shipping and agent fee, good and cheap but reliable wise still unknown so let the time tell..lol!

    On the other thread, bro RockyBoy mentioned that in his personnel experience ,higher KH reduce diatom so not bad having high KH meh..hehehe.

    Yeah, it might helps...I was on dosing regime for sometime where my kH is about 7, diatom blooms non-stop, then after getting back to CR, with higher kH, totally no more diatoms. Probably with pH lower and kH higher makes the diatom disappear. My personal experience anyway
