So here's what I've done:
1. Got Tropica Nutrition for 7ml dosing each week, with 50% weekly water changes, and leaving the biological media alone as much as possible (!)
2. Changed the substrate for Aqua Soil Amazonia II
3a. A temporary CO2 system of TetraPlant CO2 Optimat Kit - diffused into the water through an upturned Innocent drink bottle, just to get started with
3b. A drop checker (in the post from ebay...) so I know what's going on
3c. A proper pressurised system using a FE with inline diffuser, non-return valve, bubble counter, etc, once the various parts arrive from ebay
4. Lighting replaced with LED Grobeam 500 - seeing if I can replicate George's success with LEDs - I love the shimmer - on for 8 hours on a timer
5. A Hydor inline heater, keeping it at 24C
6. Cleaned about a year's algae from the Eheim 2032 filter pipes, which has increased the flow by a factor of about 10
and replaced the green bits with and perspex clear tubes for the filter return from the tank (much cheaper than glass ones). Flow around the tank now looks pretty good.
7. Various bogwood pieces from the fish shop, which I've drilled and mounted with suckers, so I can attach them to the sides of the tank
8. Cut down on the food, and introduced starvation day once a week
9. Got rid of the two worst fish. (The shadow lurking on the far right of the picture below is one of two Hypostomus plecostomus. I have now realised they were responsible for most of the floating plants, and so they've gone back to the shop, for a tidy profit
).
All the pipes are hidden through the ceiling above, into the cupboard under the stairs, which now looks like this:
The girlfriend thinks I'm mad. The immediate result probably doesn't help that:
😳
Just hoping fish survive the dramatic changes... Is there anything obvious I've missed?
