The 5050 led chipset will not give you the correct light penetration for a tank that is as deep as yours is. A cheaper/better alternative might have been a few single 50 watt chipset floodlights. They make floodlights with 4 x 50 watt chips.Well, i put in new lights... I'm running about 20, 15ft 300LED 5050 light strips. I'm running these off two 600watt solid state power supplies, and one 100watt one for a single strip that is the primary light. The other strips only get turned on when I'm actively tank watching. These replaced 3 regular shop light fixtures that had aquarium bulbs in them as the primary light and a 600watt HI sodium light as the backup. These old fixtures created a lot of heat in the tank that I found out was responsible for all the humidity in the upper part of the tank. Everything was always wet because of it and mold was an issue. With out this extra heat everything stays dry now. And they look much better too.
I'm also in the process of setting up more fry refuges in the tank. If you watch any little tight spot in the tank long enough you can see tiny fish everywhere like plankton. But none of them ever reach adulthood in the tank except live bearers like mollies and platies. So I'm making more places that give them a chance. What I'm working on now is to use those square grass mats and form them together into boxes and attach several of these together and them wrap them in more loose types of plastic plants.. all held together with zip ties. The finished deal is a hollow structure that only tiny fish can get in and out of and floats around the tank. I'm hoping a couple of these will make a difference.
That's about it really as far as anything new.
I'll get some pictures this weekend and maybe a video. I have to clean the windows first.
