Delapool's 150 gallon tank

I should mention that was Australian dollars. You could probably halve that at least.

I thought about it as a club buy perhaps but it's not quite as simple as the apogee mq200 par meter.

Into winter here. After today's water change on had both heaters click on for a bit. Good to know they still work.

I think the tetras have more colour to them but not sure if the photos agree? They are way more active - stealing food from the angelfish and getting around the tank quite a bit.








A meeting of minds -

Great pictures, love the color of the tetras that's the first time I've seen them look so good, usually at the lfs they look seriously washed out. And love the bristlenose 😊

Thanks! I think I'm lucky that I got them through a local member here. Good size to them which I think helps. I thought I might as well try full-grown large tetras.

As a fyi, the Seneye on a popular website is 199. web server and wifi are 250.!!! American $. (I thought the tag in the store said 50% off!)

Wowsie.

Anyway. Yes agree with shellyX. That is a gorgeous pic and group of Tetras. Makes me happy to see the fish which normally never see with color, looking so beautiful.

Yikes, that is a bit. Thought it would be much less

A test slide for the ammonia and ph meter lasts a month so an ongoing cost as well but I got it for the par meter so not too worried.

I'll have to pass the compliments back to the previous owner too.

In other news I managed to get a bit of BBA that had to be hit with peroxide. And more green algae on the glass than normal.

Red alt looks to be growing, val is taking over centre so fingers crossed on the pogo on the left.

The new bulbs went into the quad-t5ho and wow, are they making a difference. The old bulbs were 8 months old. Swapped to the same set of bubs (2 x grolux & 2 x 12000K).

The Seneye light meter needs an algae clean but both readings of the old and new bulbs were taken tonight with everything else the same. New lights have a much higher PAR output. Also my impression is that yes, there is a spectrum shift but it looks to me like the largest loss in PAR output is in the reds and blues, while the greens don't seem to show as much shift.

Old lights (For reference, the grey/white line is the lights; thick coloured line is I assume plant preference and I also assume the thin, coloured dashed line is what the human eye can see)


New Lights


Last thought is I'm going to need to find a source of cheap, good quality bulbs

This is interesting but also worrying. I read that old bulbs can encourage cyano (which I'm still dealing with) there was no evidence to bring any truth to the claim but still.

At the moment, more par is probably not what my tank needs.

I thought that was really amazing. I know people have looked at this before but the change in light intensity was very 'visible'.

Also I had assumed spectrum shift was blues becoming more like reds which I thought would be great but it's more like a decay of reds/blues spectrum perhaps.

I see what you mean in the BGA. It's possible I guess. The guy at the lfs did say to only change half the bulbs at a time so I guess this is quite a problem.

Wish I had tested if the blues or red bulbs were fading more but clean forgot and old bulbs in bin now.

Before I forget.

I'm going back to looking at LEDs but I will confess there is so little algae in this tank it is just about worth the cost of buying bulbs. Just doing it every 6 months is a little painful...
