    Hi all, You can get accurate figures from your water supplier for nitrate (NO3), but most people in the S. and E. of England will have elevated levels of nitrate and phosphate from their tap water.

    Can't Seem To Shift This!

    Hi all, Congratulations, plant growth looks pretty good in your tank, I'd be really pleased with that. It looks like it is probably Staghorn Algae <"(Compsopogon)">, so another <"Red Algae, like BBA">. Have a look through the <"linked thread"> for some suggestions. We don't know what triggers...

    Algae problem.

    Hi all, @Pinkmummy79 , I remembered they were from Weston-Super-Mare, and found them that way. This thread? <"Leaving Hobby or moving to .....">. cheers Darrel

    Algae affecting plants

    Hi all, I wouldn't go any shorter than five hours in the main block. You need to make sure that your plants <"have sufficient light"> (above light compensation point (LCP)). I've never kept a high tech. tank and I understand about carbon limitation, but I don't understand how 19 hours below LCP...

    Any Ideas?

    Any Ideas?

    Hi all, I've never kept Rabbit Snails, but I've always associated that sort of leaf damage with plecs, even Hypancistrus will eat Echinodorus. Ramshorn snails will eat BBA, but they only graze the sporelings, they don't eat mature tufts. cheers Darrel

    Full disclosure

    Hi all, The tank with the backing just needs a bit maintenance and a filter clean etc. The other two are much worse and my guess is that there won't be a lot worth saving, other than some of the moss and the Anubias plants. One tank has a cat litter moler clay substrate and that is now...

    Full disclosure

    Hi all, I haven't maintained any of the tanks in the lab. since the middle of March, the only thing I've done is topped the water up, but it was about 1/2 way down the tanks at that point. They don't have any fish, and a limited amount of snails etc. but were heavily planted with easy plants...

    Possible BBA and a host of questions

    Hi all, Last one for a while. <"Silica Storage, Fluxes, and Nutrient Stoichiometry in Different Benthic Primary Producer Communities in the Littoral Zone of a Deep Subalpine Lake (Lake Iseo, Italy)"> says Which I think is suggesting that silicon travels from submerged vegetation to diatoms in...
