Light output is around 20 umol/s for five hours. Thats on a 20% setting. So could be increased. CO2 is around 15 ppm.

Hello all, The tank is doing ok, most plants are growing despite the fact the tank is unheated. The cryptocoryne nurii is growing really slow, the eleocharis acicularis is hardly growing at all. I did not expect that.. any thoughts on making it grow better? The moss I want to replace by a...

nice tank, the rocks on the left look great. on the right it looks like multiple rocks are lined up front to back? it lacks a bit of interest and that makes the tank look less balanced in my opinion. I also think the scape would benefit from a midground plant around the rocks, making a more...

I prefer the frosted background, the plants will grow and make it feel less empty. But it looks more elegant and bigger in my opinion.

cool, what plants did you use?

in the front ADA la plata sand. In the planted area filter bags filled with ADA Amazonia version 2 and ADA aquagravel on top. Under the main rock there is also a bag of pumice, raising it a little and keeping it stable. The bags are there to keep the fish from digging into it, not that...

impressive plant collection!:cool::cool:

thank you both, for those who care to know: dimensions: 51cm x35 cm x 40 cm DIY lamp with 6500K 2700K en 660nm red LED's, the last two are only on during sunrise/sunset. for 5 hours a day at the moment. filtration is a hydor professional 250, and a hydor koralia 1600 for extra flow. Fish...

Hello all, After being without aquariums for some time after changing jobs and moving a couple of times, I found a place to stay for a couple of years and could not resist to set up my small tank again. My main inspiration was a song, called "de steen" (the stone) part of the lyrics go like...

I think you gave the answer yourself. to be efficient in harvesting as much energy as possible from the light that hits them, plants(and algae) also need to absorb the light that is the hardest to adsorb. Because the intelligence of nature(evolution), they have found ways to do so. So like...

I did not say you need full spectrum. I only said it seems to be preferable compared to only blue and red. RGB is by no means full spectrum and still grows very nice plants. For me any ordinary white LED is full spectrum enough (although they usually have very little violets, deep blues, cyan...

yes you are right. But there are some remarks to be made, (note I'm just a hobbyist so by no means an expert) Firstly plant growth is often looked at as the result of photosynthesis and therefor there is a focus on the absorption spectra of chlorophyll a and b. That does not take carotenoids in...

no one?

looks nice! Hydrocotyle tripartita (sp japan) should work very well, there is a dwarf variant if you want even smaller leaves. Mosses would look nice to I think. Carpeting aquarium plants would work to. Micranthemum tweediei (monte carlo) for instance. Or Bolbitis heteroclita "difformis"...

Hello all. For a new tank I ordered a pot of giant hairgrass and I wondered if I should trim back te leaves before planting it? Like I would do for E. vivipara or E accicularis..
