    Brine shrimp shells

    TLA has reminded me their main question is how much of a problem. It would be if the empty shells weren't separated out. In a moderately planted, well populated, good sized tank, would they get eaten by inverts or would their decay provide any nutrients for plants?

    Brine shrimp shells

    Not even an air atone?

    Brine shrimp shells

    I believe their intention is to cobble together some heath-robinson affair with a coke bottle and bits like an air pump that have been cluttering up the place for years. (TLA is also a complete cheap-@r$e. 🤣)

    Brine shrimp shells

    Posting for "a friend" who only wishes to be identified as The Lazy Aquarist ...😅 TLA has found an unopened bottle of brine shrimp eggs at the back of their cupboard. They're only planning of feeding them to their fish maybe once or twice a week, and not with the aim.of raising fry, and...

    Old Akadama

    Maybe I shouldn't have mentioned CEC. :D

    Old Akadama

    It's been in the tank for 10+ years. IIRC It's "hard" Akadama. As much as anything, I was wondering about it's ability to facilitate (... oh jeeze ... what was the phrase I kept reading at the time I chose it ...) cationic exchange (I think that was it?) or whether it becomes (I'm guessing here)...

    Old Akadama

    Bump (... because I still don't know the answer. :) )

    Light colour & algae

    So more PAR is good for plant growth. As I can't justify a PAR meter for purchase of a single light, is there any way to find low PAR lighting? (I can build an LED dimmer far more cheaply.) Every light I've seen advertised that mentions PAR seems to be sold on the basis of being good for plant...

    Leaf size

    (I'm sure the answers to this are going to get very technical very quickly :D :D :D but here goes ...) Is there any significant correlation between leaf size and how efficient a plant is at consuming nutrients in a tank?

    incase a hose pops off and floods your house.....

    27 possible failure points because I have two canister filters that each have their own intakes and spray bars. Then there's a system of (4) taps and (2) T-pieces that means I can use one of the filters to pump water out of, and back into the tank through barbed & threaded hose tails. (The top...

    incase a hose pops off and floods your house.....

    I used to worry about leaks. I don't now. I have something like 27 possible failure points in my cabinet, with just standard barbed fittings. The only precautions I've taken are to heat the hoses in boiling water when fitting them, put 2mm cable ties around them. No jubilee clips or anything...

    Light colour & algae

    Are cheap, domestic/ ebay (green / RGB) IP65 LED strips relatively "intense" compared to aquarium specific LEDs. My gut says they ought to be less "intense". But I've no idea how 1hr with something like that would compare with an hour of my iQuatics T5s. (Throw in a PWM driver from something...

    Light colour & algae

    Is there any colour light that is less prone to helping algae? Without working things out scientifically, I'm wondering about purely green light (as I think that what's reflected from green leaves... right?) As much as anything I'm hoping to extend the time I can watch my tank without it...

    Deep Tank Light Recommendations

    I have a tank of similar depth. For the first couple of years I had a pair of circa 36" T8 tubes. By anyone's standard it was low light and low tech. But it did ok. Then I neglected the tank for a very long while. About 6 months ago I put in a pair of Juwel length T5 tubes (I cant remember the...

    Ambient temperature

    Just in case anyone has a similar question, I think I've come up with a cheap, simple genius solution: Put a 2L bottle of water in the freezer. Once its frozen, move the bottle to the tank. (Adjust size of bottle for your tank size.) Repeat every day or two. I'll try to remember to report back...
