Hi, been lurking on here for a while...here's my attempt

Welcome from UK.

Nice start. Might want to put a light-blocker over the drains.

2 x drains



slot



Pic below is the growth after one week, very brown...



Lighting is with a 20 watt cfl each side with Stainless mixing bowls for reflectors, currently half way through second week and growing well but still a dark brown colour, any advice welcome.

Cheers

Yeah I've noticed some brown growth on the acrylic at the bottom, what do you suggest as a light blocker?

A piece of black acrylic with little legs, to stand over the drains.

Cheers, I'll give that a try

Getting a build up of algae on the slot which is slowing down the flow...any tips to prevent this?

Hang a light-blocker over it. There are many versions here if you search for them.

The feed pipe is 25mm, I'm gonna try cutting a slot in a piece of 50mm pipe and hanging that over the feed pipe, this will hopefully block the light from the top of the screen. I'll pop a pic on when installed.

Looking for a couple of LEDs to light this with, preferably off the shelf and available in the UK...anyone got any suggestions for a suitable unit?

Cheers
