Aye, that's what I thought, thanks for confirming. I will avoid. I have also been very pleased with Tropical 1-2 grow. I've also has success with aquasabi's unbranded in vitros. Not sure who the source of these are, but you get a lot of healthy plantlets - maybe four times what yiu get from...

After my first tank suffered from my inexperienced eye for feeding and some rogue snails from tgm's 'value' range, I rescaped with only in vitro plants. Snail free tanks made such a difference to my enjoyment of the hobby. Since I still have a propensity for over feeding, I am reluctant to...

Bargain!

Magic Will. It is easy - glad my ramble didn't put you off!

Hi Will Sorry it has taken me so long to get back to you. It is all based round this MOSFET. It is currently unavailable but I reckon this guy is exactly the same. I used this site for guidance. The following is how I used both with the Twinstar 900s. This first shot is an overview of...

Hi Will Apologies, weekend has been too hectic. I'll get you sorted out with photos and notes during the week. Cheers David

Thanks for your comments folks

I have absolutely fallen for Scarlet Badis. Great wee fish. I had a single male in my 60p and was desperately trying to source some females. I tried a reputable apistogramma breeder on the off chance, and he thought he might have some. So I paid for three to get posted up to Scotland. They...

Hi Will I'll try and upload some photos over the weekend, which will hopefully help.

I agree with zozo. The jack size for the Twinstar 900 was 2.5/5mm. The retailer Maplin was very helpful for me, and might be for you too if you are in the UK and have one close by. Ebay would be much cheaper though.

I found this on the Green Aqua site: LED Source : RGB-W Color temperature : 6500K Operating voltage and current : DC 24V / 2.5A Input voltage : AC 110 – 240V, 50/60Hz Lumens : 3100lm Input voltage : AC100~240V 50/60Hz Power consumption : 45W LED Life Span : 30,000hrs (Subject to the operating...

Hello aquacoen You might be in luck. From my previous research, I am pretty sure that the Twinstar 600 draw is less than 4 amps. This means that you should be able to use the TC420 or TC421 (for wireless configuration) without modding it. Have a look at the back of the power brick and...

Update. Just thought I would do a quick fact check. It seems that the ADA aquasky does not work with the TC420. Here is some more info: https://www.flowgrow.de/beleuchtung/ada-aquasky-601-tc420-t43117.html Sorry, should have checked before original post.

I am pretty sure they are saying not to use their dimmer with the 90. I don't think it's rated for the amp draw of the light. You could get the 90 and try an aftermarket dimmer rated for higher amperage, or hack a tc420 as described here.

Hi Danny, I recommend this: https://www.amazon.co.uk/Tc421-controller-programmable-intelligent-lighting/dp/B071V6LRCB/ref=sr_1_1?ie=UTF8&qid=1515944054&sr=8-1&keywords=tc420 I use it with the Chihiros AquaSky and it is great. I am sure it will also work with the ADA fine. The TC420 and...

Just to update this for completeness. I finally got round to modding the TC420 with this mosfet, for use with the Twinstar 900S. I bought some 6 amp cable from Maplin and a couple of DC jacks (2.5/5mm). This means that I didn't have to mod the Twinstar cables in any way. The power from the...

Just a quick follow up. My order arrived in two parts within a week (all dry stock). Very well packed and no damage. Thanks Green Aqua.

Great Black Friday deal with 20% off today only. I just placed a biggish order. Hopefully their service for international customers is as good as Aquasabi's. Judging by the quality of the store, I am confident! I was looking to include 25kg of rock but the delivery would have been 135 euros...

Thanks so much for that reply. I actually had the same sitting it in my Amazon shipping basket. https://www.amazon.co.uk/gp/aw/d/B01J7H2WCK/ref=ox_sc_saved_image_1?smid=AONS7HEF348I5&psc=1 A lot pricier but that's the privilege of paying 90 quid a year for Prime. You get humped twice...

Yeah, scratch that. I need to connect the twinstar to a 6 amp driver soldered to the pwm gate of the tc420. Yurgh.

Hey Zozo. Just a thought. Could you drive the one light from two channels? Obviously both channels would have the same dimming schedule. Sounds too easy so it probably won't work!

Thanks Zozo. I shall look for another solution.

Thanks Zozo. Would the risk be limited to the tc420 or do you think it could extend to the light and/transformer? Also, I'm guessing not having a fuse increases the risk of fire if abused. Not sure if I want to risk a fire, even if there is 200 litres directly above it. Would limiting the...

Hi folks. I have a tc420 running a Chihiros 60 fine and dandy. I have a twinstar 90 on the way for the larger tank. I've established that this is a 5 amp light. What are the risks of running through a tc420 given that it has max 4 amp per channel? Any thoughts would be much appreciated.
