Hard to get camera to focus but the Algae's growing all over the glass and on the Lava rocks and Coral
bought a piece of 3mm clear Perspex and cut it to a flush internal tank size using a 4.5" angle grinder and diamond cut off wheel then x2 - 2mm x 15 mm notches on opposite sides to allow for x4 Light clips. Drilled a 20mm hole in the centre for taking water samples, water changes, feeding and as a finger hole to remove and fit. Works a treat no condensation above and below it pools and drips back in the tank.
My next fettle was to tidy up the lighting wire Rats nest, down to the 'it'll come in handy one day' scrap pile in the 'Shed' - the columne from my black + white enlarger, a piece of chromed copper pipe from fitting the shower gave :-
Bare bulbs hanging looked a bit naff so light shades ???? Eureka !
I used Energizer 5 watt 6500k GU10 bulbs and GU10 to bayonet addapters
The x2 small tanks (12 ltr) were in Home Bargains at £12 each with an internal (mains) carbon sponge filter, small net, plastic plants and a tank back drop. One's set up for the Marimo with x2 Zebra Danioes to cycle it then some Fresh water Shrimp, the other's going to be set up as a Brackish SG 1.005 half way house for Nerite Snails etc.
I was getting lots of condensation which then ran down the outside of the tank leaving a salt crust when it evaporated,
